stock mb5 I picked up for 300 bucks. TITLED, needs a ton of work but the motor makes 150psi of compression cold and its got spark so it should be a ripper soon ;) EDIT: SHES A RIPPER!!! still needs a front brake caliper and tires and tubes but she runs, rides, and shifts fine. EDIT: finished the bike, still looks like a rat but its got lights and brakes and drives lol, 55mph bone stock. did 60mph down a large hill. fast for a little 50cc lol wish it were cleaner and the title was in check. :/
