Its a frame from a 70 Yamaha R5 with a 420cc side shaft motor and a snowmobile clutch. Thats right no gears just throttle and go! It gets about 60 mpg and will go about 70mph. It gets up to speed very quickly and smoothly. The back end was lowered 2.5inches and the frame itself was stretched 7inches. I love it, its fun to ride and handles well. Whether you guys like it or not is up to you. But i built it so im riding it!
