Crankshaft Polini For Race Minarelli AM6

Polini Crankshaft For Race for Minarelli AM6.

Upgrading the crankshaft is essential when seeking maximum reliability and performance in high-level setups. The Polini For Race has been designed to push Minarelli AM6 engines to the limit.

With a 39 mm stroke, this reinforced crankshaft optimises engine inertia and improves efficiency. Its forged connecting rod withstands extreme mechanical demands, making it ideal for operating at high revolutions without compromising durability. In addition, its specific balancing reduces vibrations and ensures a smooth and continuous power delivery.

For complete performance, the kit includes two high-speed C4 bearings, with the flywheel side bearing reinforced thanks to an increased inner diameter of 20 mm. This technical improvement increases resistance under extreme usage conditions.
