Malossi RHQ High Compression Crankshaft for Aprilia / Piaggio 50cc 2T Models

Compared to the standard crankshaft the Malossi RHQ is significantly stronger in its construction – particularly around high stress areas such as the little end, the big end bearing and the conrod itself. The RHQ also features a ‘high compression’ design, which in basic terms means that the webbing of the crank is completely filled in leaving no extra space for air. This makes the overall area inside the casing of the engine smaller, which increases the compression and power.

For optimum performance benefit this crank should be installed with a new set of Malossi C4 Clearance bearings.

This is an option that should be very seriously considered for any bikes with 70cc kits installed – particularly of a 9 port or bridge port map such as the Malossi MHR Replica or MHR Racing cylinders.
