Suddenly Turns Off 馃毃

My 2021 Suzuki V Strom 1050xt bike turns off suddenly while I am riding it for long distances, especially when I want to stop or turn, so what is the reason and did you encounter such a situation?

What turns off? The engine, the whole bike and electrical system?
The whole bike turn off & I shall re-starting it
I havent heard of it but first thing to check it is the battery connections.

Many have reported the bike shutting down when standing on the pegs

They are moving the kick stand with their boot shutting it down

Ensure you are not doing the same thing and insect the stand switch to ensure all is good down there

You can join the 2 stand switch wires as a test of your boot and the switch

That's what I suspected, probably because I had a wide steel piece in the side stand馃浀馃憤馃徑 Thx.
Yeah, if that piece is too heavy it'll pull the sidestand down over bumps and such. Most foot enlargers are made of lighter materials, like carbon fibre or plastic, for this reason.

Do you have a centerstand as an alternative? You can zip-tie the sidestand to the frame so it can't move, and ride around for a bit. If the symptoms disappear you've found the cause.

Also, if you do a visual inspection, note that - at least on older stroms - the sidestand was held up by two springs, one inside the other. Both need to be there to supply enough force. It's incredibly hard to see though, unless you are specifically looking for it.

The OP reported that the whole bike shuts down, not the engine "The whole bike turn off ". The side stand switch will not turn off the bike, only the engine.

People describe the same situation differently, I offered the most likely one

The engine just turns off and restarts with the red button, even though the gearbox is in the first or second gear
From that description you must have pulled in the clutch. What happens if you leave the clutch out?
If it is a momentary sidestand switch disconnect, either from a soft spring over a bump, or an errant boot - the bike should restart by itself.
On the earlier bikes a bad clutch switch could cause the same problem but I don't have any experience with your bike.

You should try starting the bike while it is in gear without pulling in the clutch lever.

Be warned it may lurch forward during this test.

If the motor will crank the clutch switch is the likely cause.

Thank you all, On my last trip, and after I covered a distance of about 120 km, when I reached road intersection point, I had the same previous error, although I made sure that the side stand was tight and that I gripped the clutch will gear was on #1 (the engine turned off and I had to restart it again ). Can鈥檛 understand what is the reason yet!? It happened only when I ride for long period
I'm not that informed on the 2021 1050, but could it be the bank angle/fuel cutoff sensor? I had a similar issue with a GoldWing I use to own. It would cut off going down the road if I goi into a buffeting situation or if I turned at a sharp lean angle. I would have to stop cycle the key and it would start and go on its way. I figured it out by putting the bike on the side stand, starting it, putting it in gear then violently shaking the bike from side to side. I figured out how to bypass the sensor rode the bike for a couple months with no problem then finally changed the sensor. :unsure:

Thank you for more information Sami. "This only happens when I ride for a long period".
Could this mean that the vent in your fuel tank is blocked, causing fuel starvation? Try riding with the fuel cap partially open (but be careful not to spill fuel).

The more information you can give us the better our suggestions.
Do the electrics cut out?
Do you need to stop for a while before the motor will restart?
Does it always cut out at a similar length of riding time?
Does it ever cut out at cruising speed - or only when you are slowing for a turn?
Does it cut while on winding or bumpy roads?

I am sure that we can identify the problem with more detailed information. "The bike stops and I need to restart it" covers a whole lot of scenarios. I realise that you are posting from Saudi Arabia. My Farsi isn't that good. :) Cheers.

Thank you very much for asking such questions (and my answers are in brackets), thank you, I hope I can diagnose the reason
Best Regards 馃尯馃尯馃尯 (love you all over the world)
Has anyone with a DL1050 had anything like this?
All I can think of is fuel, but caused by what? Running too lean on a closed throttle.
Bad fuel, blocked fuel tank breather, blocked air filter, air box hoses not sealing on the throttle bodies.
I think it's related to the clutch safety switch (which may not be as simple as a mechanical switch on the lever since this machine will start without clutching in, unlike prior years).

The symptoms are substantially similar to the issues I experienced when I over-rode the clutch switch on my '07 .... I didn't realize that the switch sent a signal to the ECU to retard timing when the clutch was pulled, so the ECU thought the clutch was always in and I got retarded timing all the time and occasional stalling as I was clutching in to downshift.

So clutch switch or other retarded timing issue is my thought.

鈽 The problem still persists with me almost routinely

See the problem in this link (below) at 40 seconds
