Cylinder Kit Polini 66cc cast iron Racing D.43mm 10mm pin Piaggio Bravo / Grillo. Cast iron “Racing” cylinder in proven Polini quality.

The “Racing” version has even more power than the “Sport” version due to its optimized exhaust design with additional ports and should be used with a matching tuning exhaust to support the additional power output.

The kit includes a cast iron cylinder, piston with rings, 10mm piston pin and circlips, a high compression cylinder head (43mm) and a matching gasket set. The small end bearing must be purchased separately.
