Righetti Active NEW (Gen2) Noise Filter D.30mm Red/Black (KZ-KZ2) (2021 Homologation)
The filter cartridge used for the Active noise filter is made of polyester and it can be cleaned with solvents, gasoline and compressed air.
This cartridge has a filtering of particles of more than 10µm (10 thousandths of a millimeter) and it is evaluated as the best compromise between air flow and air cleaning.
10µm value allows also the filtering of the impurities produced from the front brake system: it is usually between 15µm and 30µm and it is know these impurities are very aggressive with the inside parts of the engine.
The new cartridge has a reed barrier to modify the air flow and reduce the turbulence inside the airbox.
The new inlet pipes have a better Venturi effect with a better performance.
