Crankcase 8.1 Fireblade 100cc for shaft Ø increased by 25mm Piaggio Version (Short Arm 10 ”wheel)

Complete 8.1 "Fireblade" 100cc engine crankcase for Piaggio version with a 25mm larger diameter shaft (short swingarm for 10-inch wheel).

Made entirely from solid aluminum using CNC machining, this crankcase is of exceptional quality. Compared to the 8.1 100cc engine crankcase, it features enlarged diameters in the thermal section to accommodate the longer drive shaft (8.1 / R-18, C47 B100 Ø84). This increased inertia results in a more powerful engine. Unique in the world, this crankcase features a water/air cooling system for the crankshaft. Its upper section ensures optimal fluid dynamics, and its modular design allows for complete flexibility thanks to its three separate parts. It can accommodate a 10-inch rear wheel. Not for road use. Made in Italy.
