Optimized and lightened full cheek racing crankshaft suitable for Puch Maxi S / N, as well as Supermaxi LG1 mopeds / mopeds with a 1-speed E50 engine.
This special crankshaft has 1 mm more stroke and gives your engine more torque and compression to tease the last power reserves out of the cylinder.
The precisely fitting 939 gram full cheek crankshaft has proven itself in our latest test series and delivered uncompromising power.
All balancing holes in the cheeks were sealed with aluminum inserts for maximum pre-compression. The solid connecting rod is fitted with a more stable 16 mm connecting rod bolt and is also sealed with an aluminum insert. In addition, the polished connecting rod ensures optimum flow behavior of the air-fuel mixture and the additional lubrication slots guarantee clean running even at high engine speeds.
The lightened cheeks on the inside ensure even better balancing and smooth running.
