Description

14° Polini Evolution Air Speed fan wheel

As well as being exceptionally designed, this fan wheel from Polini is intended for tuned Piaggio engines that need extra cooling at the variator.

Made from an aluminum alloy for lightness and strength, with an outer diameter of 115mm and reverse-oriented cooling fins, it strives to increase airflow at the transmission up to 30% around 13,000-15.000 rpm and as if that in itself isn’t impressive, it turns out that this Polini Evolution Air Speed fan wheel absorbs 5% less of the power from the crank, which means more power actually goes to propulsion rather than being lost in the transmission.

Note: This fan wheel has a 14° inclination on the back.
