Vespa PX200 P200E Rally 200 Bell Shape Race Crankshaft Reed Valve 60mm Stroke 110mm Conrod

Bell Shaped

Reed Valve Engines Only - 60mm Stroke.

"This new Mazzucchelli bell shaped 60mm stroke crank for reed valve induction Vespa 200cc engines offers great benefits over conventional crankshaft designs.

The design of this crank lowers the primary compression of the engine, allowing a greater volume of fuel mixture to enter the crankcase. When combined with a powerful expansion chamber exhausts reverse pulse, it enables more fuel mixture to be available during combustion. Furthermore, the symmetrically arranged, bell shaped design allows an unhindered flow of fuel mixture and also helps prevent the crankshaft twisting due to the equal weight of the webs.

In addition the crankshaft is exactly weighted to counterbalance the Malossi CVF piston and has a manufacturing tolerance of just 2% at the bearing.壽_�▔踎��br>
