The Malossi MHR gearbox cover is engineered for racing and sport upgrades on Piaggio 50cc scooter engines. Gravity-cast from heat-treated aluminium-silicon alloy and precision machined, this reinforced crankcase provides exceptional structural rigidity while reducing overall weight to handle demanding race workloads.
By integrating dedicated needle roller and ball bearings, this transmission cover reduces friction by 4% compared to standard setups for smoother power delivery. It is completely interchangeable with the original factory cover and is fully compatible with both original and Malossi secondary gears.
