Polini For Race ø12 CrankshaftRef : POL00249A / 1126050

Polini For Race ø12 — reinforced crankshaft for Minarelli scooters (CY, MY, CW). Designed for urban riders looking for a robust and reliable base when upgrading their engine, this Polini crankshaft incorporates essential elements to support piston/conrod setups suitable for 50cc/70cc preparations.

• Manufacturer reference: 210.0049/12
• Engine compatibility: Minarelli CY / MY / CW
• Piston pin: 12 mm (allows the use of specific pistons, replaces the original 10 mm pin)
• Recommended use: 50cc/70cc cast iron engine groups, up to 14 hp

The conrod is made from a single block, and the crankshaft is heat-treated to increase its wear resistance. The parts are balanced in the workshop to minimize vibrations and power losses, resulting in a smoother operation of the crankcase. Built to withstand the pressures of urban preparations, it provides a solid foundation for those looking to enhance a tuned setup.
