Polini PX200 Race Crankshaft
57mm Stroke
110mm Conrod

The Polini crankshafts are very cleanly finished and convince with their well thought-out details:

• flow-optimized control cheek
• well balanced
• stable connecting rod
• extended inlet control angle
• trunnion: 20mm

The width of the sealing surface on the rotary vane cheek is 16.8mm wide as on the original PX200 shaft.

The extended inlet control angle results in a larger time cross section and allows a significant increase in power over the whole speed band.
Very nice stable shaft which provides more bandwidth in every engine.
