High-quality Crankshaft from the manufacturer Malossi from the high-performance MHR line.
HPC stands for High Primary Compression, which means it is a compact wall crankshaft.
Thanks to high pre-compression, better cylinder filling and better shifting of the rev band are achieved.

The result is a slightly weaker start and much more power. This version has a special 80mm connecting rod for all cylinders with a 12mm pin.
