Racing Carbon: The Racing Carbon air filter utilizes a specialized polyester material with a wire diameter of just 22 micrometers and is integrated into a carbon frame. In this filter, the rubber is thus completely replaced by carbon. This air filter was developed for the racetrack and uses patented technology to make it waterproof?the only filter of its kind in the world. Its unique weave pattern can filter out dirt particles up to 85 micrometers in size, giving it the highest airflow of any air filter on the market. This filter is used exactly as is in the MotoGP by most teams. All Ducati, Aprilia, and Honda bikes are equipped with it. This filter is used exactly as-is by the Ducati Team in the World Superbike Championship.
In Switzerland, sports air filters are not permitted on public roads. Sprint Filter is a company from Latvia and has patented filter technology.
