After mounting a lighter fan wheel or a tuning ignition, the fan wheel may drag on the fan cover. In order to avoid this problem, it is very common to mount washers as spacers to raise the fan cover. However this may lead to a gap between the fan cover and the crankcase which in turn, due to the decreasing airflow, reduces the cooling capacity.

With the Polini fan crankcase spacer for Vespa small frame this problem is completely avoided. The Polini spacer lifts the fan cover, closing the gap completely. This way the complete air flow is guaranteed and the cooling is maintained.

The Polini fan crankcase spacer is made of stainless steel to better resist to wear and comes with 3 bolts longer than the original ones to compensate washer addition and to grant the best thread grip.
