An ad on this site for minipocketrockets.com led me to their minature motorcycles. Some of them they claim to reach 70mph....sounds pretty good for a complete machine that only costs $600. These are 110cc 4 stroke engines, pushing around 15hp peak. Any have one of these bikes? I can't imagine the quality being very good. But for only $600, they'd be some cheap fast fun. They are about 35in tall, so they aren't as small as the typical 'pocket' bikes. Anyone have anything to say about them?
