High-end racing crankshaft suitable for manual Puch X30 NS / NL Z50 engines (air cooling).
Attention: Not suitable for Puch X30 Velux engines (blower cooling)!
High-quality and precisely fitting, 942 gram full cheek crankshaft, which has proven itself in various load tests. This was designed for use in engines with a large increase in power.
All balancing holes 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 pin, which is hollow on the inside for better balancing.
In addition, the connecting rod bearings are silver bearings, which have excellent emergency running properties.
