Description
High quality Malossi MHR crankshaft for Minarelli Vertical 12mm pin engine.
HPC stands for High Primary Compression, which means that it is a compact wall crankshaft. The high pre-compression results in a better cylinder filling and a better displacement of the rev band. The result is a slightly looser start and much more power. This version has a special connecting rod for all cylinders with 12mm piston pin.
Features:
- Crankshaft material: 18 NiCr Mo5.
- Forged monolithic crankshaft and rotating mass.
- Machined and tooled to the highest precision.
- Five heat treatments on all components.
- High surface precision for improved reliability.
- Dynamic balancing up to 16.000 rpm.
- Connecting rod forged from 18 Ni Cr Mo 5 with copper plating, coupled to the crankshaft with precision needle cage for high speed.
