Technical description

Gear-box cover for scooters and Minarelli Yamaha 50 cc engines, designed for racing and for a sport upgrade of standard production scooters.

Malossi, after revisiting the gear box assembly, has reduced friction drastically by replacing the original cover with the gravity cast cover, assembled with special bearings.

This cover, machined with high precision machines, has increased strength and reduced weight and able to withstand very high workloads, typical in racing.

Perfectly interchangeable with the original cover and complete with all necessary bearings and seal, the Roller Crankcase helps reduce friction by 4%.

Technical Characteristics and Components

• Reinforced gear-box cover, gravity-fed permanent mould casted with aluminium-silicon alloy, heat treated.
• Increased secondary shaft bores for two bearings - Two (2) special needle roller bearings - One (1) ball bearing with increased load capacity - One (1) oil seal.
