Xpeschon and myself have rode many miles together and today he was working on his bike and when he shut it off it went to beeping. I ask him what that was and he said it was warning him the park brake was not set. Maybe this is a feature only on the SE models since mine is SM. Needless to say we were both surprised, me that his beeped and him that mine did not beep. The beeper would make a good back up alarm.
