Racing Carbon: The Racing Carbon air filter uses a special polyester material with a wire diameter of only 22 microns and is incorporated into a frame made of carbon. This filter thus completely replaces the rubber with carbon. Designed for the racetrack, this air filter uses a patented technology to make it waterproof, the only filter of its kind in the world. Its unique weave pattern can filter out dirt up to a size of 85 microns and thus has at the same time the highest permeability of any air filter on the market. This filter is used 1:1 so in MotoGP by most teams. All Ducati, Aprilia and Honda are equipped with it. This filter is used 1:1 in the World Superbike by the Ducati team.
In Switzerland a sport air filter is not allowed on public roads. Sprint Filter is a company from Latvia and has a patented filter technology.
