Optimized and lightened full cheek racing crankshaft.
Due to the two splines, this crankshaft is suitable for manual Puch X30 NS and NL, Velux, MV50, MKII, Maxi HP2 and custom mopeds / mopeds with Z50 engines.
In the new 2023 version, in addition to the balancing holes in the cheeks, the lower connecting rod bolt has also been sealed with an aluminum insert for maximum pre-compression. The solid connecting rod with the stable 16 mm connecting rod bolt has also been 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 therefore smoother running.
