Just this am my friend on his Triumph triple dropped it in the parking lot- but not for the common mistake of forgetting to put down the kick stand- but for leaving the bike in neutral on a slightly downward angle. It doesn't take much for the bike to begin moving and the kickstand to move and whammo-
The only damage we could find was a broken clutch handle- that he says was designed to break on a tip over...
Do not leave in neutral at a stop- whether that being parked or at a stoplight- you never know when you are going to want to pop it into gear quick to get out of the way of a car that doesn't see you.
No neutral! I have this argument with my riding buddies all the time; and today one of them lost that argument
