Malossi MHR gearbox cover for Yamaha Aerox/ Minarelli engines.
This is a great upgrade for racing bikes and for standard production mopeds.
This cover is a completely revised assembly which has been machined to have increased strength and reduced weight and able to withstand very high workloads.
It incorporates proper needle and ball bearings which is a vast improvement over the standard casing where the shafts run in the casing without bearings.
An increase in bike performance comes from significantly reduced frictional forces. Clutch shaft oil seal included.
