zaz,
BUY ONE AND DON’T LOOK BACK! much easier than a 2-stroke to install.... That bike looks like it will do just fine... but if you have the money.... the GT1 is the way to go for the bike.... looks insane, and it is designed to be motorized.... got my setup through broped... they call it the “gnarly davidson”.... pretty funny, but legit!... either way, you are going to be pleased with this motor... have fun, and post some pics
