Malossi RHQ High Compression Crank shaft for SR50 Ditech (Factory, Sport)

Description Malossi RHQ High Compression Crank shaft for SR50 Ditech (Factory, Sport) 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. The RHQ crank for the SR50 Factory/Sport Ditch has the oval shaped wheel for the compressor on the right hand side of the shaft. This is necessary to run the compressor unit on all inject Morini motors. This crankshaft will also fit the April Scarabeo 50 Ditech.   The Malossi RHQ Crankshaft offers a high compression, mid-race solution that can take a whole lot more punishment than the standard Aprilia crankshaft.

For optimum performance benefit this crank should be installed with a new set of C4 Clearance SKF Bearings and seals. 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. R.H.Q. CRANKSHAFTS – The crankshaft is the heart of the endothermic engine. – All aspects of engine performances start from the crankshaft. – It is not possible to obtain good engine performance and reliability unless a top-quality crankshaft is fitted. – This is why Malossi produces only the very best in crankshafts.
