AIR NUMBER 12 on Vespatronic, Parmakit and Overrev ignitions.
12 fan blades
made by injection moulding from fibre reinforced plastic in black
also suitable for M200, Smallframe like Largeframe
At 10.000 rpm 50% more air performance than a Vespatronic fan without costing more power.
The plastic fan wheels of the many suppliers were too expensive for us and freely after the motto something is always we did not like many fans. The Parmakit fans consume too much engine power, Vespatronic fans made us a little too little draft, the color does not fit to every scooter and the available milled fan wheels cost much more than the plastic fan wheels.
A very serious disadvantage of the milled fans on the race track is their stability. If the rider crashes, the blades on aluminium do not break off, they bend and unfortunately the crankshaft is often damaged by the torque applied.
The air number 12 is lighter than the aluminum alternatives, which allows the engine to rev faster and be more aggressive on the throttle.
The air number 12 is intended to be an inexpensive replacement for the available fans, an alternative to Vespatronic and Parmakit, and most importantly, CNC fan wheels. Air number 12 will also fit Polinitronic ignitions with modifications (holes must be re-drilled offset).
Also fits on Vespatronic pole wheels for Smallframe as well as Vespatronic pole wheels without shrunk on additional flywheel mass. Therefore not plug & play suitable for Vespatronic Largeframe (PX, T5, Rally, Sprint, VBB etc.).AI-translation
