Here is a good webpage from webbikeworld about a stalling problem that occurs in the new BMW scooters. Here is the link:

I just wanted to let you know that I took it to the dealer where I bought it, Honda/BMW of Hollywood, and they fixed the problem the first time.
It was happening frequently and I could easily duplicate the problem for them. The mechanic said that the adaptation for the stepper motor was off or out of adjustment. I don't know what the means, but he said he reset or re-installed the software for it and that fixed the problem. It does not stall any longer.
I tried many times to make it stall and it runs great now. They also did a software update for the instrument display, which was a recall item. I thought maybe this information would help some of the others who are having problem getting theirs fixed. Thanks again for all of the great information."
