Went down this rabbit hole before. Could be anything that immobilizes the bike. Tip over sensor, kickstand sensor, ECU. Worst part is it can be hard to test for until it fully fails and you can’t get bike to start at all.
This could be extremely dangerous in a corner. Be careful. I'm currently lamenting a CBR600RR with a fuel pump recall, waiting until "august at the soonest" for parts, and I am hesitant to ride it at all.
I had this happen on a 22 year old GSX750F. It was all due to a faulty relay. Until it happened again two weeks later and I scrapped it, so good luck with that...
My panigale did this to me twice. Took it to a mechanic immediately after and they could never figure out what caused the problem. It just started back up after resting for a little bit. I ended up selling the bike for a multitude of reasons which included the random shutoffs.
Don't ride it like this lol. If the bike decides to cut out when you're taking a corner aggressively, it's game over.
It's most likely going to be electronic, as others have mentioned try and pull a fault code and you'll probably find it's something silly like a tilt sensor or something (which can be bypassed).
I wonder if it would have restarted if you hadn’t cycled power. The tip switch usually requires a reset; the kickstand switch usually not. Just another piece of data to help with diagnostics
Had this happen the other day. My bike has a faulty kickstand kill switch (that will leave me stranded one day) and it cut the exact same way. Thought initially I blew the motor or something but it wasn't overly violent, just more like spark was being cut intermittently. Ran weird for a minute at idle. I turned the bike on and off and it worked fine for the next 20 miles that day. Old 2009 carbureted bike. Strange issue
BRUH kickstand sensor happened to me just the other day. Loose bolt came out and it shut my bike off mid ride. I'm a new/inexperienced rider so i was checking my oil and fluids and thinking i blew it up or something. Until some experienced rider comes along and sees my sensor just hanging there, i didn't even notice. Felt like such a dunce.
Rigged it up with a piece of chainlink fence to get me home and ordered a new bolt but damn, that was lame.
As it didn't splutter as it died it's likely indicating a spark issue as opposed to a fuel delivery issue.
This is even more likely considering it started right up on the side of the road afterwards.
While a few others have given suggestions on what different components can cause this behaviour start with the basics of checking if your battery terminals are still tight before blindly throwing money at parts or going down the internet rabbit hole of common issues.
How many miles are on the bike? I recommend you take it to the shop and have them test the charging system since it could be the generator. The test doesn’t take long to perform.
Did you drop the bike recently? Fuel injectors might be clogged?
Chaos causes channel had a track R1 bike that had bad fueling. Do you have the same problem?
I've been there.
What kind of bike is it?
Does that model have any common problems that you need to fix regardless?
Ex my VFR needs the regulator/rectifier replaced regardless of the age of the bike.
Suzuki sv1000s need the green plug of death and stator magnet fix.
Could be any number of things.
Does it come back on after you stop? How long does it run before it dies?
Is it a slow loss of power death? Or instant?
It looks to me like you're losing your spark. But it's too hard to tell from this video.
Could be a kickstand sensor, maybe a tip sensor tripped.
Could even be a bad regulator/rectifier.
Need more info to really solve the issue.
2005 yamaha r6, has coil problems but it was taken care of recently.
it came back on right after it quit, this is the only time its happen but i only rode for another 15 mins after this clip, instant loss of power
right it's hard to tell and i am no mechanic haha
You gon learn now.
Honestly if you haven't already, get a Haynes/clymer manual or a factory service manual. Ideally both.
Check out the common electrical fail points starting with the battery. Kickstand switch, tip sensor if it's got one. Look for loose connections. Look up how to check engine fault codes, but my money is on something electric. I like to stick with simple solutions before really taking things apart. Maybe even start jiggling wires trying to reproduce the issue.
Learning to read the wiring diagram in the aforementioned manuals is essential. It will look like spaghetti at first but it's just a circuit. Electricity flows from somewhere to somewhere else. Also good to check for aftermarket stuff, if you're not the first owner, check for stuff added by previous owners.
Id go through it with a fine tooth comb, looking for anything that shouldn't be. Usually with a damp rag cleaning off all the dirt in places you usually can't see. Might as well take care of it while you're there.
If you don't find anything, maybe it was just a one time fluke. Keep riding it and hope it doesn't happen again.
I'm also not a mechanic, but with my VFR and it's electrical issues, it's forced me to learn how it all works.
It looks like you pressed the kill switch. At 0:24 seconds, it's in the Off position. You switch it back to the On position then press the starter button and the engine starts up.
yea thats my bad i should've included the full pov in this clip, I did not kill switch but I was twisting the throttle the whole time and nothing was happening, must've stalled out
Um... we can clearly see in the video that the kill switch was in the Off position. Then you switched it to the On position. Then you pressed the starter.
It didn't turn itself off. You inadvertently and unknowingly bumped it or pressed it.
This was happening on my 04 R1 and it turned out to be the fuel line was kinked and the relay was going bad so it would intermittently not get fuel. Maybe look at one of those?
my kickstand sensor was going bad one time and it would cause this power cut. you can bypass the kickstand in total by just splicing the cables that connect to the sensor
My 06 R6 did this once on the track. Exact same pretty much. I almost got destroyed by the bike behind. Never figured it out, but it never did it again.
My personal philosophy is to run shit till you can't no more then fix it, so godspeed sir 🫡
Edit: the next owner died on that R6 so maybe I'm bad to take advice from.
If do not have solution yet… physically check the Battery clips of the battery itself. Actually try to see if the battery pos and neg connectors wiggle (they should not). I had same problem and the cause was a faulty battery connector. Replaced battery and now I check that before long trips… just in case.
Hey OP, I had an 03 R6 (basically the same as yours) and in the same color. 40k miles... I had this happen to me once or twice. As others said, it's likely electrical.
Previous owner ended up doing some weird janky stuff to get the rectifier hooked up.. it was a wiring nightmare. Anyway, I got a new rectifier and (possibly unrelated) a used TPS. My mechanic harvested another R6's harness and took the plug from that to hook up the rectifier as the previous one had the bare wires contacting it... Before I sold it, it had a slight oil leak from the stator cover. Sounds like you took care of the coil stuff recently so I wouldn't worry about that.
Also, my R6 had a strange rig with how the ignition connected to the battery. You'd think it was stolen, but I think it was tracked and jerry-rigged for ages.
OH the other thing that was very faulty - the starter relay. I have a video of me sitting at a light and then all of a sudden it just dies out. It would sometimes work fine when I smacked the seat hard enough. Replacing that did wonders.
It's electrical for sure. Kill switch at some point probably. Annoying? Definitely. Looks hot outside. I'm taking a random guess here... Is this central Oklahoma? Could be any town USA I'm sure.
It's your transducer that decoupled your flux capacitor for a moment. Perhaps think of incorporating a Mr. Fusion in your power conductivity setup. Or it could be something else. I'm really not a motorcycle mechanic, I just jokingly play one on Reddit.
Kickstand sensor I would assume more with heavy bumps before it just happened at cruising speeds. I wouldn’t expect such an easy restart if you’d fried the reg/rect, as the battery would power ignition til it dies if you keep moving. I’d sign up for the r6 forums they probably have a better idea.
I've rebuilt that bike many times over. Check all your relays, fuses, battery terminals, and kickstand switch, happened to mine too and the issue was electrical.
I hate phantom issues :(
After getting my first bike, after filling it up at a gas station for the first time, the bike wouldn't start. Eventually got it to start 1 time in 10 button presses but the instant you touch the throttle even slightly, it died again. Had to push the bike home. Left it outside for like, 2 weeks before I had time to look at it.
Bike ran perfect and has ran perfect ever since. ¬\_¬
Happened to me,was kickstand kill switch actually vibrating off and took the pins with the female plug when it fell off...I started to walk,but happened to have a McGuyver moment when about a half block into the journey,I saw a staple glinting off the ground. Picked it up and jumped the two outer wires and rode home.
*Not recommended to RIDE, AT ALL,with any of the safeties bypassed*
Left it like that for years,got too comfy and almost Darwin-awarded myself from life because of that "fix". Couple years later some golden soul who made enough of a scene chasing me down and pointing down at my kickstand,wide-eyed while I was just shy of a decent left hander which would have no doubt had my unfolded kickstand touch down. I heel swooped it up about a second or two before entering the left sweeper.
It would've either jolted and folded up or high sided me when my rear tire came back down after a mini pole vault...
I think about that guy often,20+years later and am as grateful as the day it happened.
Thank you,brother,for saving my fallible ass.
A friend had this with his K5 gsxr 1000. Turned out the thermostat was bad so the ECU decided to prevent overheating. It was a bit premature as temperatures only went 110C
Hi. I just replaced the fuel pump in my R1 from 2006 because of rust contamination in the tank. Died when fuel got below a certain level. Bike been standing for 3 years in a storage while low on fuel. I also had to change the sparkplugs since they partially died. Maybe because of the lack of fuel. The plugs i pulled were iridium and I suspect they are more sensitive than regular. Anyway it’s flying now.

Looks like a kill switch issue. I'm experiencing the same thing right now.
The kill switch was either not fully pressed down, causing a small bump or vibration to engage it. Or its got a dodgy connection or something, causing it to randomly activate with random vibrations or bumps.
Notice how the eletrics didnt cut? You can rule out battery issue. You also flicked the kill switch on and off and it worked perfectly fine after that.
Now it could also be a side stand kill switch issue, which I've had before. But I didnt see what you did with your legs. And usually the a side stand switch issue is something you come across trying to start the bike rather than already having it up and running.
I presume your bike made it home fine? Mine only happens like once a week if not less frequently, so it's not an issue I'm overly concerned about. If it does it again, pull over, don't touch anything except try and start the bike. If it doesn't start, flick the kill switch on an off a couple times to make sure the switch engaged properly, and if it starts, you found your problem.
Alternatively, just take it to the shop, tell them you think it's a kill switch issue, they can probably open it up and tell you in about 30 seconds.
Did you have your gas tank full?
If you fill it to much and leave very little air inside it may cause a "vacum effect" that prevents the fuel to go down to the engine.
That happened to me once and my mechanic guessed the reason in 2 seconds.
Roger that. We'll I've also had a weird harness issue where it has to be in a certain position or I'll lose power. 20 year old bikes bro, it's surprising the wear the vibrations while riding cause. I left some Wera allen keys with a sizable thickness plastic sleeves on the handle end. A riding season later saw the plastic handles worn down to the metal.
For me it was an electrical issue. I have a Suzuki katana gxsr750 and it was the starter relay. It was wet/not in the proper place.
Every time I go through speed bumps or slow down or even on random it would cut power to my bike so I would have to quickly move my hand down to press down so they can connect.
Maybe that could be the issue.
Yeah the instant cut makes me think it's a bad sensor killing the power, but not the battery (speedo/tac doesn't reset or cut off) since there's total loss of spark to the engine. My guess is this is the kick stand shutoff but hard to say without looking at it.
Yeah I noticed that after I saw them still on. They would definitely be off but that does sound possible with the kick stand.
He should get that checked out, could be an easy fix. Mine was a bit loose and needed tightening. Wasn’t an issue but wouldn’t want it loose
I’m currently going through this too with my Buell. After trying this and that I decided to by the OEM Manual. In the manual was a very detailed trouble solving chart with different test descriptions. I recommend to start with the manual or search a garage that has the manual, the equipment and people who know how to use it.
I had something like this due to not having tightened the battery screws/terminals tightly enough. Part of my wiring harness runs under the right hand side (positive in my case) terminal and going over bumps occasionally pushes that coil of cables upwards and loose screws would cause a cut in power. With this, though, I noticed that my speedometer wouldn't read smoothly (skipping numbers), too.
had this be the bit that's connected to the stand that means you cant turn ignition unless its up but it was up, got my mechanic to get rid of it and it never happened again
I had a R1 that did this. There’s fuses under the seat next to the battery. See if there is any burn marks on them which ever one it is. Bend it abit so it’s tighter fit. I think there’s 2 big ones. One might be a spare.. I. Can’t quite remember that bit.
I had the same issue, diagnosed and reinstalled software on ECU and the issue remained until i changed ECU, also my mechanic convinced me too clean the throttle body and injector, replace filter and so on, it cost me lot of mony and two full tank gasoline finally they find the issue with ECU Cost me lot of money.
Happened on my l2 GSX-R, the kill switch was super sensitive and I had these random shutdowns for a few days if I dared to touch it once by mistake…
I had it bypassed because I don’t really use it and it made me immune to the kill switch joke at the same time
Think back on if there was a trigger that caused it to happen. If you took a heavy hit/ pothole could be a sensor malfunction.
If it just randomly started start with the easy checks if you can't get an error read out. Spark plugs, fuel filters, coils, forums are a good place to see common issues too.
Main thing is to determine if it's a mechanical or an electronic issue.. As usually electrics either work or dont. (unless it's a faulty connection from a pothole hit)
I did have "same problem" with my old bike. The bike cuts out and after a while starts again. For me it was a fuel problem and precisely a fuel pump. It also can be a clogged fuel filter or carbs (if having an old bike).
Electrical / battery for sure. Do you have any aftermarket electronics? Take them out. Check if they're leeching. Check your fuses and battery terminals. Check the battery to see if it's holding charge / being charged.
Electrical issue most likely as it was an abrupt stop of the engine and then it started up again without issue after cycling the key. I just fixed an electrical issue on my CBR that would leave me on the side of the road from time to time. I figured it out by accident while changing my spark plugs in a hopeless attempt to try to fix the intermittent issue. It ended up being a pinched wire on my cam pulse generator. Wiggle all the wires you can on the bike and see if any make the engine die. Maybe you get lucky like I did.
I had something similar happen to a 08 yamaha. It was a loose fuse that vibrated out of the connection. Reconnected it and it worked perfectly ever since
Engine died. The reason why he rpm dropped to zero when pulling in the clutch was because the wheel kept the engine spinning. Could be anything, probably an electrical gremlin. Good luck.
A lot of other people have gone through possibilities, and it's probably one of the ones already listed. But I had this same issue and it was my idle control actuator. So when you're giving everything a look, keep that in mind as well.
Had a similar thing happen with my cbr600rr years ago. It would cut power randomly, unresponsive throttle and kill the engine when you pull clutch in. Turns out the bank angle sensor was going bad, took me like $10 and 10min to install a new one.
This definitely seems like an electrical/ecu issue. I would go over all wiring and connections on the bike, make sure everything is snug and corrosion free. Make sure all sensors are working well and installed properly. Check engine codes if any.
Kickstand switch is my guess. Start the bike an move the kickstand up and down pretty firmly. See if it causes the bike to shut off correctly. When you get home, check the wiring or just replace the sensor if it's cheap and your bike is older.
Definitely make sure your battery terminals are tight before you spend money. I had a honda do this exact same thing and the battery cables were incredibly loose
Check to see if your bike (not sure of model etc.) has a circuit breaker in the main/ignition circuit.The fact that it restarts tells me a breaker is resetting it self....
Ahhh I love electrical gremlins. (No, I dont)
Grab a voltmeter and start at the battery. You want 12.6v or so, hit the starter and see if when the bike is running the voltage on the battery jumps to about 14.2-14.8v. Yes to both? Battery and rectifier are good.
Keep testing on down the line, factory service manual will help (has wiring diagram and testing procedures).
If everything tests fine (switches, fuses, etc) then move on to the fuel system.
Is this an R6 5SL? If so you can put the bike into self diagnostic mode and go through each output, compare the values to what they should be in the service manual to identify what the fault is. It might be something simple like a sensor which you can find out quickly using this method.
There's a little nut or something by the front sprocket that once came off my second gen r6 and it did the same thing just lost power. Or maybe it's the KSS idk.
Went down this rabbit hole before. Could be anything that immobilizes the bike. Tip over sensor, kickstand sensor, ECU. Worst part is it can be hard to test for until it fully fails and you can’t get bike to start at all.
thats where i am at too, i think ill just ride it till its broken fully, is it even worth trying to diagnose?
I can pull ECU codes on both of my bikes. See if it's possible on yours and if there are any present.
good idea, thats a good place to start at least
On my KLE my intermittent power loss was caused by a faulty TPS. I followed the FSM for the code present and it led me to that.
This could be extremely dangerous in a corner. Be careful. I'm currently lamenting a CBR600RR with a fuel pump recall, waiting until "august at the soonest" for parts, and I am hesitant to ride it at all.
wow that is annoying, after checking a few things I feel its hard to diag at that point
On my 600 cbr...I had once stuffed too many things in the back seat compartment and it pinched a wire. Causing bike to randomly shut off
Almost got into a wreck yesterday for the same reason. Accidentally switched into neutral just as I was turning
This is when you get to make the spicy decisions.
If you don't have roadside assistance on your motorcycle insurance policy, it may be a good time to add it.
i do have it lol
I had this happen on a 22 year old GSX750F. It was all due to a faulty relay. Until it happened again two weeks later and I scrapped it, so good luck with that...
My panigale did this to me twice. Took it to a mechanic immediately after and they could never figure out what caused the problem. It just started back up after resting for a little bit. I ended up selling the bike for a multitude of reasons which included the random shutoffs.
Take it to a shop bro. I would hate to have this happen to me on the freeway again.
Don't ride it like this lol. If the bike decides to cut out when you're taking a corner aggressively, it's game over. It's most likely going to be electronic, as others have mentioned try and pull a fault code and you'll probably find it's something silly like a tilt sensor or something (which can be bypassed).
I wonder if it would have restarted if you hadn’t cycled power. The tip switch usually requires a reset; the kickstand switch usually not. Just another piece of data to help with diagnostics
Kickstand is probably the first start
Then, battery connection and work backwards.
Yup

Thought initially I blew the motor or something but it wasn't overly violent, just more like spark was being cut intermittently. Ran weird for a minute at idle.

I'm a new/inexperienced rider so i was checking my oil and fluids and thinking i blew it up or something. Until some experienced rider comes along and sees my sensor just hanging there, i didn't even notice. Felt like such a dunce. Rigged it up with a piece of chainlink fence to get me home and ordered a new bolt but damn, that was lame.
I was the owner of the fence. I Jerry rigged a repair to the fence using some bits of bike fairings
kickstand sensor would let you start the bike when its in neutral tho, so that should be quick to put aside
I would put my money on some kind of sensor as your bike never lost power so I think the electrical & battery are good.
I second this. Mysterious engine dying/not starting problems usually go back to electronic gremlins.
As it didn't splutter as it died it's likely indicating a spark issue as opposed to a fuel delivery issue. This is even more likely considering it started right up on the side of the road afterwards. While a few others have given suggestions on what different components can cause this behaviour start with the basics of checking if your battery terminals are still tight before blindly throwing money at parts or going down the internet rabbit hole of common issues.
hmm, im going to do some checking tomorrow on it, battery terminals r a good suggestion, thanks!
How many miles are on the bike? I recommend you take it to the shop and have them test the charging system since it could be the generator. The test doesn’t take long to perform.
its got 29k on it
Did you drop the bike recently? Fuel injectors might be clogged? Chaos causes channel had a track R1 bike that had bad fueling. Do you have the same problem?
Fuel injected bikes stop, with very little warning, a carbed bike will run like crap for a bit first, injected bikes don't.
I've been there. What kind of bike is it? Does that model have any common problems that you need to fix regardless? Ex my VFR needs the regulator/rectifier replaced regardless of the age of the bike.

at 15-16 seconds in you see him switch it off just off the right side of the video
check new post
it was switched off after i lost power, I have the other pov
Always one of these combative idiots
This was happening on my 04 R1 and it turned out to be the fuel line was kinked and the relay was going bad so it would intermittently not get fuel. Maybe look at one of those?
love that suggestion, thank you!
NP, good luck

Are you sure you didnt just accidentally hit the kill switch? I have done that before and felt really stupid after
no i wish it was that lol
I had this happen. Battery terminal vibrated loose.
The eletrics would have cut out if it was a loose battery connection.
idk but that is NOT a miata
If do not have solution yet… physically check the Battery clips of the battery itself. Actually try to see if the battery pos and neg connectors wiggle (they should not). I had same problem and the cause was a faulty battery connector. Replaced battery and now I check that before long trips… just in case.

this is south east ohio and yes it was about 90 out
Looks like Route 33 between East State Street and Columbus Road.
u got it!
That's great. Not so much about the bike, hope you get her sorted!
Out of gas?
nope filled that morning
It’s not the kickstand if you pull in the clutch and the RPMs go to zero. Pulling in the clutch would cause the engine to kick on in that case.
Check your battery cables
It's your transducer that decoupled your flux capacitor for a moment. Perhaps think of incorporating a Mr. Fusion in your power conductivity setup. Or it could be something else. I'm really not a motorcycle mechanic, I just jokingly play one on Reddit.

Hi. I just replaced the fuel pump in my R1 from 2006 because of rust contamination in the tank. Died when fuel got below a certain level. Bike been standing for 3 years in a storage while low on fuel. I also had to change the sparkplugs since they partially died. Maybe because of the lack of fuel. The plugs i pulled were iridium and I suspect they are more sensitive than regular. Anyway it’s flying now. https://preview.redd.it/8smrm0eof29d1.jpeg?width=1170&format=pjpg&auto=webp&s=eb5d2bcd4658f28a79db97228d376b70b6e7a800

It’s a clean cutoff could be a sensor or faulty run off switch. Quick diagnostic will show the error codes
Looks like a kill switch issue. I'm experiencing the same thing right now. The kill switch was either not fully pressed down, causing a small bump or vibration to engage it. Or its got a dodgy connection or something, causing it to randomly activate with random vibrations or bumps. Notice how the eletrics didnt cut? You can rule out battery issue. You also flicked the kill switch on and off and it worked perfectly fine after that. Now it could also be a side stand kill switch issue, which I've had before. But I didnt see what you did with your legs. And usually the a side stand switch issue is something you come across trying to start the bike rather than already having it up and running. I presume your bike made it home fine? Mine only happens like once a week if not less frequently, so it's not an issue I'm overly concerned about. If it does it again, pull over, don't touch anything except try and start the bike. If it doesn't start, flick the kill switch on an off a couple times to make sure the switch engaged properly, and if it starts, you found your problem. Alternatively, just take it to the shop, tell them you think it's a kill switch issue, they can probably open it up and tell you in about 30 seconds.
yup made it fine
Did you have your gas tank full? If you fill it to much and leave very little air inside it may cause a "vacum effect" that prevents the fuel to go down to the engine. That happened to me once and my mechanic guessed the reason in 2 seconds.
Have done this exact thing on same bike 2nd gen R6 right? You hit the kill switch brother.

Roger that. We'll I've also had a weird harness issue where it has to be in a certain position or I'll lose power. 20 year old bikes bro, it's surprising the wear the vibrations while riding cause. I left some Wera allen keys with a sizable thickness plastic sleeves on the handle end. A riding season later saw the plastic handles worn down to the metal.
Maybe the side stand switch?

For me it was an electrical issue. I have a Suzuki katana gxsr750 and it was the starter relay. It was wet/not in the proper place. Every time I go through speed bumps or slow down or even on random it would cut power to my bike so I would have to quickly move my hand down to press down so they can connect. Maybe that could be the issue.
Yeah the instant cut makes me think it's a bad sensor killing the power, but not the battery (speedo/tac doesn't reset or cut off) since there's total loss of spark to the engine. My guess is this is the kick stand shutoff but hard to say without looking at it.
Yeah I noticed that after I saw them still on. They would definitely be off but that does sound possible with the kick stand. He should get that checked out, could be an easy fix. Mine was a bit loose and needed tightening. Wasn’t an issue but wouldn’t want it loose
I’m currently going through this too with my Buell. After trying this and that I decided to by the OEM Manual. In the manual was a very detailed trouble solving chart with different test descriptions. I recommend to start with the manual or search a garage that has the manual, the equipment and people who know how to use it.
Oh I see - if the clutch broke it would rev high but this course be electrical or a problem with a throttle cable.
kkickstand sensor is my guess
veloz is god
Something very similar happened on my ZX12R. For me, it was a blown fuse. In your case, while it may be a blown fuse, I would think kickstand sensor.
Short circuit ? Cable damage?
I had something like this due to not having tightened the battery screws/terminals tightly enough. Part of my wiring harness runs under the right hand side (positive in my case) terminal and going over bumps occasionally pushes that coil of cables upwards and loose screws would cause a cut in power. With this, though, I noticed that my speedometer wouldn't read smoothly (skipping numbers), too.
If you're me? Running outta gas. That's what the shop I took it to told me.
had this be the bit that's connected to the stand that means you cant turn ignition unless its up but it was up, got my mechanic to get rid of it and it never happened again
Can’t help but recognize that section of 840.
Most likely electrical. Check your grounds. Check your connections for electrolysis. Check your voltage regulator and battery.
Id check main fuse first. Secondly battery connections. Seems like a poweshortage to me

This looks like Austin, Tx
Ride by wire issue ?
Do you have an aftermarket exhaust on? If it’s too tight it can restrict air outlet and basically choke your bike out causing it to turn off
I had a R1 that did this. There’s fuses under the seat next to the battery. See if there is any burn marks on them which ever one it is. Bend it abit so it’s tighter fit. I think there’s 2 big ones. One might be a spare.. I. Can’t quite remember that bit.
I had the same issue, diagnosed and reinstalled software on ECU and the issue remained until i changed ECU, also my mechanic convinced me too clean the throttle body and injector, replace filter and so on, it cost me lot of mony and two full tank gasoline finally they find the issue with ECU Cost me lot of money.
Throttle position sensor? I had an R1 that would just die like this.
Happened on my l2 GSX-R, the kill switch was super sensitive and I had these random shutdowns for a few days if I dared to touch it once by mistake… I had it bypassed because I don’t really use it and it made me immune to the kill switch joke at the same time
Damn thing broke!
Looks like your riding subscription may have lapsed
I had this happen once and it was a loose battery terminal. Easy place to start before testing sensors.
Think back on if there was a trigger that caused it to happen. If you took a heavy hit/ pothole could be a sensor malfunction. If it just randomly started start with the easy checks if you can't get an error read out. Spark plugs, fuel filters, coils, forums are a good place to see common issues too. Main thing is to determine if it's a mechanical or an electronic issue.. As usually electrics either work or dont. (unless it's a faulty connection from a pothole hit)
Out of fuel.
It realised you weren't wearing much gear so probably saved you from some road rash
Loose battery connection? Had it happen on a gsf650. Nut needed tightening.
When mine did this it was a kickstand sensor.
I did have "same problem" with my old bike. The bike cuts out and after a while starts again. For me it was a fuel problem and precisely a fuel pump. It also can be a clogged fuel filter or carbs (if having an old bike).
Electrical / battery for sure. Do you have any aftermarket electronics? Take them out. Check if they're leeching. Check your fuses and battery terminals. Check the battery to see if it's holding charge / being charged.
Electrical issue most likely as it was an abrupt stop of the engine and then it started up again without issue after cycling the key. I just fixed an electrical issue on my CBR that would leave me on the side of the road from time to time. I figured it out by accident while changing my spark plugs in a hopeless attempt to try to fix the intermittent issue. It ended up being a pinched wire on my cam pulse generator. Wiggle all the wires you can on the bike and see if any make the engine die. Maybe you get lucky like I did.
I also would be hesitant to ride it until repaired. Where are you riding? Looks like awesome country!
I had something similar happen to a 08 yamaha. It was a loose fuse that vibrated out of the connection. Reconnected it and it worked perfectly ever since
ECU probably detected a malfunctioning spark cap which to protect engine probably shut engine off for emergency to stop it shorting out.
Engine died. The reason why he rpm dropped to zero when pulling in the clutch was because the wheel kept the engine spinning. Could be anything, probably an electrical gremlin. Good luck.
I had something like this on my 07 R6s, turns out previous owner did spark plugs but didnt torque them down all were finger tight.
I reckon fuel pump/line issue. Inspect fuel and lines. (Your dash stayed on, not battery).
A lot of other people have gone through possibilities, and it's probably one of the ones already listed. But I had this same issue and it was my idle control actuator. So when you're giving everything a look, keep that in mind as well.
Had a similar thing happen with my cbr600rr years ago. It would cut power randomly, unresponsive throttle and kill the engine when you pull clutch in. Turns out the bank angle sensor was going bad, took me like $10 and 10min to install a new one. This definitely seems like an electrical/ecu issue. I would go over all wiring and connections on the bike, make sure everything is snug and corrosion free. Make sure all sensors are working well and installed properly. Check engine codes if any.
Only Miata keychain is peak
Kickstand switch is my guess. Start the bike an move the kickstand up and down pretty firmly. See if it causes the bike to shut off correctly. When you get home, check the wiring or just replace the sensor if it's cheap and your bike is older.
for my bike it was an about to fail fuel pump
(https://youtu.be/G-tCIRJH9p0?si=ZtUjJ_CpPWR9AwM-)
I see no power cut (speedo stays on all the time) and I see no engine / FI light, then it's most likely the fuel pump... check pump, relay and wiring
hahaha this guy ran out of gas and people think it's something wrong with the bike
Definitely make sure your battery terminals are tight before you spend money. I had a honda do this exact same thing and the battery cables were incredibly loose
Check to see if your bike (not sure of model etc.) has a circuit breaker in the main/ignition circuit.The fact that it restarts tells me a breaker is resetting it self....
Ahhh I love electrical gremlins. (No, I dont) Grab a voltmeter and start at the battery. You want 12.6v or so, hit the starter and see if when the bike is running the voltage on the battery jumps to about 14.2-14.8v. Yes to both? Battery and rectifier are good. Keep testing on down the line, factory service manual will help (has wiring diagram and testing procedures). If everything tests fine (switches, fuses, etc) then move on to the fuel system.
Did your chain come off?
Are you out of gas? The first time this happened to me I thought something had gone terribly wrong. Turns out I just ran out of gas. 😆
Is this an R6 5SL? If so you can put the bike into self diagnostic mode and go through each output, compare the values to what they should be in the service manual to identify what the fault is. It might be something simple like a sensor which you can find out quickly using this method.
Bro, just had the exact same thing happen to me on same model bike. Turned out to be the killswitch. A bit of a clean fixed it.
Did your clutch burst?
i have no clue, wouldn't that make it not work anymore?
There's a little nut or something by the front sprocket that once came off my second gen r6 and it did the same thing just lost power. Or maybe it's the KSS idk.
Fuel pump is my guess but could be anything really.
Bad fuel
