Cylinder Kit, Polini - VSX (207cc)

One of the highest-output cylinders available. This cast-iron kit shines in the lower end and midrange, and can have you pulling wheelies regularly. While it may not last quite as long as the nikasil Malossi or Pinasco kits, it's the most "bang" for the buck! Perfect when mated with a Prima pipe ! The 26/26 carbs are very popular with this cylinder too.
