Looks like somebody found a way to do the impossible... Make a hayabusa uglier.

the extra seat really comes in handy!
if i were that guy, i wouldn't know either which one to pick up on my bike!

look at that guy, he is a monster ,creepy

I would be up for guessing.. That the extra wheel helps balance the bike for a quick take-off, without the front wheel leaving the ground. (Depending on how far back the driver pulls the throttle..)

-- That kicks ass.

wtf...
