2020 r1250rs side stand lurching - NormR - 10-30-2024
Good evening all,
Just for clarity, I bought my bike last year with 16,000kms and this season I happily put another 11,000kms. My issue started last week. I push the bike out of my garage and start it on the side stand to warm up for a few minutes. Obviously the bike is in neutral. Once i get on the bike I pull up the side stand and the bike lurches forward stalling. So far, its happened 4 times. The only way I can explain it, is that I am somehow knocking the shifter as my foot passes. It does surprise me though, as I am not "BIG" footed and this has never happened before. I'm going to re-adjust the shifter higher to try to keep the side stand away from the shifter but I'm worried there might be something more afoot. Has anyone here have a similar issue that didn't involve the "big foot" syndrome?
cheers
Norm

So just to clarify, you get in the bike which is in neutral and idling, you upright the bike off the side stand, you flip up / back the side stand, and the bike somehow lurches forward?
No can’t say this has ever happened to me. For the bike to lurch forward and stall it has to somehow be in gear so yes your left foot must somehow be bumping the gear lever as the foot is holding the side stand up and back. I can’t see any other explanation. That said I can’t see how the foot would reach inside that arc to bump the gear lever.

Exactly!
I adjusted the shifter upwards about 1/2inch tonight to see if it makes a difference and I'll experiment the next time I take her out. I'm even going to put it on the centerstand first to give me that extra security when it lurches........
If this somehow turns out to be an electrical gremlin I will really not be impressed with BMW

To keep things simple don't let the bike idle to warm up.
You don't need to warm it up before riding.

Only happened to me while deploying the side stand. Shifter and sidestand are pretty close when the stand is stowed. And I don't start it until I am aboard and ready to ride. Just take it easy for a little while.

Hmmmm ... shows how we're all different. I never start the bike after sitting on it. Always start before because when I sit it am ready to take off. Starting the bike up first - usually just before putting on the helmet and then gloves - allows instrumentation boot up and engine warm-up to happen before I ride off.

Thats what I do. It doesn't run for more then a couple minutes while I'm putting on my helmet and gloves. I took out the bike today after adjusting the shifter a bit higher and had no lurching while taking the bike off the side stand
I also discovered the higher shifter position to be much more comfortable, especially during downshifts. Unfortunately the weather here is taking a wintery turn so rides are going to be very rare if not impossible until spring..........

Glad you got it sorted.
