Crankshaft -QUATTRINI (for Quattrini engine casing C1 and Pinasco) – full circle web, 53mm stroke, 105mm conrod- (Ø=24mm cone) di tendenza adesso!

Quattrini solid cheek shaft for the Quattrini engine case C1.

Compared to a conventional crankshaft the shaft is much wider and therefore fits only the Quattrini engine case C1.

This version has a 53mm stroke and a 105mm conrod.

A corresponding cylinder (Polini EVO diaphragm) is therefore necessary or alternatively, with spacers and/or turning, the height of the cylinder must be adapted to the desired timing angles.
