Details

Malossi has taken the design of performance parts to the next level. The introduction of their Malossi Crankcase Kit RC-One has revolutionized scooter tuning by presenting innovative technology ready to house the latest and newest racing components.

To date, riders were forced to equip their tuned racing scooters with original or OEM quality crankcases that were designed for limited power and performance. They had to modify these crankcases so they were capable of dealing with the requirements and strain of 70cc and more powerful engines. But times are a-changing, and Malossi's RC-One crankcase, developed and manufactured in Malossi's Research & Development centre, represents a milestone in building the ultimate racing engine.

Malossi basically started from scratch, discarding traditional concepts in crankcase design, and came up with a completely redesigned transfer and inlet port area with short stud bolts while at the same time increasing structural rigidity.

Special attention was paid to the reed valve area - employing the newest CFD (Computational Fluid Dynamics) software, Malossi engineers were able to calculate and design optimum angles and dimensions for reed valve placement.

They got rid of auto-lubrication and traditional water pump technology in order to minimize power loss, a pre-drilled opening allows for the use of a vacuum fuel pump. The opening for the electric starter was closed. Shock absorber mounting was redesigned and reinforced.

The RC-One was designed for Malossi MHR 70cc / 94cc cylinders with special 'flange mount' system. The crankcase can be used with disc and drum brakes.

If you are into high-end equipment - this is it!
