Crankshafts: The resilient heart of your moped engine

The crankshaft is the most stressed component in any tuning project. Higher engine speeds and increased mean pressure require solid cheeks and first-class bearings to minimize vibrations and ensure the service life of your engine. We stock a wide selection of standard and racing shafts for legendary classic mopeds from Piaggio, Peugeot, MBK and Simson.

In our range you will find the extremely durable RHQ shafts from Malossi, precisely balanced full cheek shafts from Polini and tried and tested classics from Mazzucchelli and Top Racing. Regardless of whether you opt for 10 mm or 12 mm piston pins or convert your housing to diaphragm control - our shafts ensure smooth running and maximum stability so that your engine does not break down even at maximum power.
