High-end racing crankshaft suitable for your Puch Maxi S, N and Supermaxi LG1 moped with a 1-speed E50 engine.
This special crankshaft has 1 mm more stroke, the additional stroke gives your engine more torque and compression and thus tickles the last horsepower out of the cylinder.
The high-quality, precision-fit, 975 gram full cheek crankshaft, which has proven itself in various load tests, impresses with its excellent balance ratio and good speed stability. It was designed for use in engines with a large increase in power. All balancing bores in the cheeks have been sealed with aluminum inserts for maximum pre-compression. The solid connecting rod is fitted with a more stable 16 mm connecting rod bolt. In addition, the connecting rod bearings are silver bearings, which have excellent emergency running properties.
