The Polini CNC machined impeller for Vespa is made of aluminium, machined from a single block.

It is fully designed to support the very rapid revving of powerful engines!

Perfectly balanced for less vibration, it increases engine rpm by approximately 300 rpm.

The aluminum it is made of helps dissipate heat, maintaining optimal cooling of the thermal group.

You will notice micro-machining which actually helps to cool the part and the air projected into the engine.
