I used to ride with a guy who had one a looooong time ago. It was a lot of fun to ride (of course I was a wee bit younger also). I remember it would do wheelies for miles. You didn't have to worry about balance or any of that crap. Just throttle and rear brake
. Being behind it on a ride was no fun though
. Handguards, chest protector, googles and a visor were a MUST.
