Malossi 61mm, 166cc kit, fits Sprint, Super, GTR 125, TS 125, P125E, PX125E, P150X, PX150E, Stella and COSA 125 (can also be modified to fit on some old 125 and 150's). Extra 2 stroke power, larger transfer ports, and a larger exhaust port.
Includes BIG bore cylinder, high compression head, CVF flow piston, rings, wrist pin, pin clips, gasket set, carb jets, Malossi stickers, and instructions. This will bump up your old Vespa in horsepower, and with a pipe and carb you can increase it much more. (This kit needs the ports chamfered. We can do this for you)
*UPDATE 11/13/12* Malossi has updated and improved this kit with different porting for more low RPM torque!
