Fixed front half-pulley -OEM QUALITY Airmax- CPI 50 cc

The fan wheel sits on the crankshaft in front of the variator. The pitch of the disc harmonizes with all current Tunig variators as well as with the original Vario. This thing is an absolute MUST for all tuned scooters! The larger fan blades provide better cooling of the variator, and the material used can build up a better grip to the V-belt.
