Two of my favorite minibikes, Bonanza has A Robi 6.5 hp engine replacement front forks, seat is a Bonanza repro. I just added new LED headlight and new cat taillight.
Fugi Go Devil was bought as a bare frame that was re-welded to take a regular engine, has a 5 hp honda , with a modified front fork and the seat off a exercise machine. Both a cool ride...
