Dave, I came off the back of the even larger C90 once getting a lift home. The road home was a 1 in 4 hill and my lift giver was probably about 17st (plus my lesser weight on top of that for the poor old bike). He was a little clumsy in kicking it into first on the steepest part and the front wheel went up in the air and off I went... I'd had a few too many and all I could do was laugh.
