Hello,
I can help you : I didn't modify my 250 ETZ as a supermoto but to get a super look, in modfying many things like the rear wheel (wider and in 17'), the tank, the seat, the top-cylinder, the rear fender, and the exhaust. To get a seventies motorbike look, like the beautiful italian trial motorcycle...
