Reinforced gear box output Top performances Minarelli am6 (415, 420 & 428 + gearing choices)

Pinions Top Performances are machined in ultra strong materials, which is why we recommend to the competition and runs. In addition, they are in different teeth and different sizes of channels which can enable certain to pose a chain and a broad crown size: 428 often used on more powerful motorcycles. This allows much more strength and accuracy on large configurations.
