2Fast Passion 100cc Minarelli Crankcase

The 2Fast Passion 100cc crankcase is a high-end engine base developed for very high-performance Minarelli Horizontal setups.

Made from cast aluminum alloy and then re-machined by CNC, this crankcase features enlarged sections for the intake, crankshaft, and variator to allow the use of large displacement engine configurations.

It is specially designed for FL (Flanged Mount) cylinders with external mounting, notably the compatible 2Fast FL R and Malossi Testa Rossa.
