You have a very valid point. I'm 5'11" so getting my foot down at stop lights has never been an issue; unless I'm dealing with a 450cc dirt bike.

My GF is about 5'2 and stopping a motorcycle in traffic is actually a pretty big deal. She isn't tall enough to put her foot down, without awkwardly angling the bike. The only bike should could ride of mine is a 250cc ninja. The 400cc+ supermoto was way to awkward/tall for her to comfortably ride.

I'm totally open to the self-balancing idea now.
