CRANKSHAFT MALOSSI MHR ENGINE MINARELLI VERTICAL PIN 10MM
High quality crankshaft from Malossi MHR. HPC is the acronym for High Primary Compression (high precompression) , which means that it is a compact wall crankshaft.
Thanks to a high precompression, a better cylinder filling is obtained and a better displacement of the speed band.
The result is a slightly looser start but a lot more power.TECHNICAL CHARACTERISTICS
Semi-crankshaft and forged monolithic rotating mass.
Elaboration with machines and tools of the highest precision.
With five heat treatments on all components.
High surface precision to improve reliability.
Dynamic balancing up to 16,000 rpm.
18 Ni Cr Mo 5 forged connecting rod with copper bath, coupled to the crankshaft with precision needle cage for high speed.
This is why Malossi exclusively produces absolute 1st quality crankshafts.
