Crankcase Malossi MHR RC-One PiaggioMalossi 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.Malossi RC-One - state-of-the-art racing crankcaseTo date, tuners were forced to equip their tuned racing scooters with original or OEM quality crankcases that were designed for limited power and performance. These OEM cases often limit machining options and restrict the installation of high-performance parts. They had to modify these crankcases so they were capable of dealing with the requirements and strain of 70cc and more powerful engines.Malossi tackled this issue head-on, discarding traditional design constraints and developing the C-One case from scratch. The transfer and intake areas were completely reengineered, and the structural rigidity was significantly improved. 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. The shock mount has been repositioned and reinforced for better stability.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.Technical specifications Malossi RC-One CaseMaterial: die-cast aluminium silicon alloyWeight: 5.25kgSpacing crankshaft - primary shaft: 270mmStud bolt spacing: 48x48mmCrankshaft bearing: 20x47x14mmWheel axle bearing: 20x47x14mmNeedle bearing for transmission cover: 16x22x12mm360° manifold for VHST and PWK carburetorsReed valve: VL18Cylinder base seat: 61mmPump case bore: 78mmStud bolts: 8.8 tempered steelSuitable for: Piaggio short and long
