Suitable for internal nut type gear sets (no bearing on crankcase cover). Completely interchangeable with the original, it ensures greater torsional rigidity and the internal design guarantees a significant increase in power. The increase in horsepower and structural rigidity translate into a more precise and reliable driving experience. Increased intake duct and reed valve pack allow to accommodate carburetors with diffusers of Ø 35 to 39mm. The product comes from Team 8.1’s track experience. On these crankcases you can use all the original components, from the transmission, to the gears to the crankshaft. Made in Italy product.
