Complete engine casing 8.1 “Fireblade” 100cc for shaft Ø 25mm Piaggio version (long arm for 10"-12 ”-13” wheel).

In aluminum, machined entirely from solid and CNC machined, of supreme quality. Compared to the 8.1 100cc engine casing, it has enlarged diameters in the thermal part in order to accommodate the increased shaft 8.1 / R-18, C47 B100 Ø84. In this way, thanks to a higher inertia and a different balance, additional power is added to the engine. The only scooter crankcase in the world with water and air cooling system for the crank chamber. Always fluid dynamics inside the top and all the flexibility of the modularity of three separate parts. It can accommodate the 10 "and 12" -13” (rear) wheel. Road use prohibited. Made in Italy product.
