Description

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
  • available with 57mm (std) and 60mm stroke
  • trunnion: 20mm (except PX200, 57mm stroke: 22mm)

The width of the sealing surface on the rotary vane cheek is 15.8mm wide as on the original PX125/150 shaft.The PX200 version has here 16,8mm

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.
