Complete engine casing 8.1 “Fireblade” 70cc for shaft Ø increased by 25mm Minarelli version.

Made of aluminum, machined entirely from solid and CNC machined, of supreme quality, excellent rigidity and a first-class design. The internal fluid dynamics has been studied in parallel with the reed valve for the maximum possible thermal efficiency. The only scooter crankcase in the world with water and air cooling system for the crank chamber. The modularity of the assembly allows: _a reduction of the propagation of heat between the thermal part and the transmission _more versatility for a possible change of displacement. _a reduction in spare parts costs (it is possible to independently replace each of the three parts that make up the crankcase). The crankcase has a Minarelli application, but Piaggio transmission and gears. It can accommodate the 12”-13” wheel. Road use prohibited. Made in Italy product.
