Brand new crank and piston. The motor was blown up when I bought it and fixed it up and runs like a champ. Fast for a 125. Wisco piston and hotrods crank. No scams please and face to face sells only please. 6203935855. Just got back from dunes and has a paddle on it that would go with it. Great bike to learn on. I have extra rear sprocket for it since the original is getting wore out
