Polini Evolution Driven Pulley for Piaggio based 2t 70 - 94cc engines.
The larger 134mm diameter face allows the belt to be in a a much higher gear from initial set off when using the Polini over sized drive belt. This gives greater acceleration and much more consistent RPM characteristics right through until the belt reaches the lowest point of the pulley which also gives more top speed. An absolute must for any racer who is serious about being competitive.
