Crankshaft for scooters with Peugeot horizontal engine. Suitable for 50ccm and 70ccm sport cylinders. Application range up to 13000 rpm. The lower connecting rod bearing is equipped with a copper thrust washer. The delivery includes piston pin bearing. Designed for alternator rotor mounting with pin.

Our recommendation: The crankshaft bearings and shaft sealing rings can also be replaced (available separately). A good 2-stroke oil extends the life of the crankshaft. A crankshaft should be changed under normal use after 20000km at the latest. An engine damage due to a defective or worn crankshaft causes further problems on the engine.
