Stage6 CNC drive face/ front pulley for Piaggio 50cc 2-stroke scooters.

Drive face with optimised drive face angle. In order to keep costs down, original racing drives are usually cast or - even worse - pressed steel. When these parts are cooling down after casting, the metal is still molten and the drive face angles can often vary. Due to the fact that racing engines have a very narrow power band, these tolerances have direct consequences on the power output. 

In contrast to those standard versions; the Stage6 racing drive is precisely CNC cut out of solid material. All in all, more than twelve different versions were tested to find the optimal angle.The high quality alloys and the special surface coating used in this drive face make cooling fins unnecessary. The reduced mass has of course positive results for the power at the rear wheel.

NOTE: Due to its lightweight construction, the Racing Drive Face has no external teeth. This makes it impossible to use the electric starter!
