Description
High Quality Crankshaft from Malossi MHR. HPC stands for High Primary Compression, which means that it is a compact wall crankshaft.
High pre-compression results in better cylinder filling and better displacement of the rev band.
The result is a slightly weaker start but much more power .
TECHNICAL CHARACTERISTICS
Forged monolithic half-shaft 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 in 18 Ni Cr Mo 5 with copper bath, coupled to the crankshaft with precision needle cage for high speed.
This is why Malossi only produces crankshafts of absolute top quality.
