I was thinking over winter to build my own. I would use a bigger CRF50 china copy alumnium frame with 12″ wheels F+R. (32″ seat height)

160cc GPX Crate engine, with a 30mm carb(not included), 18front 30rear sprockets.
Swap the handlebars for universal clip ons
Cut and reupholster the seat, then weld up a rear section that looks like a GSX’Rs. Weld up a tank cover and bolt in on the plastic one. Bondo, shape & paint it all flat black or metallic blue
12″ Dunlop race supermoto tires
Buy LED lighting for rear, acerbis diamond headlight assembly for the front
Buy a two brothers exhaust and chop it so it’s aligned in the center (duals?$)
Universal speedometer kit, mirrors, LED turn signals
front fender, welded bondoed and painted
turn damper

but is it worth it? and Who knows if it’s heavy enough to stick to the road..how much it would co
