The DNA motorcycle air filter for the Piaggio Beverly 400 uses multiple layers of oil-impregnated cotton gauze supported by wire mesh. Its airflow is 200.4 CFM, compared with 91.6 CFM for the stock filter, while its filtration efficiency is 98–99%.
DNA FCd design technology shapes the pleated filter to fit the contours of the airbox and increases the filtration area. The frame is made of polyurethane and the seals are made of EVA, which is resistant to fuel, oil and high temperatures.
