The DNA air filter for the KTM 125 Duke features four layers of oil-impregnated cotton gauze between two layers of wire mesh. The cotton material provides 98–99% filtration efficiency, while the oil resists moisture and high temperatures. DNA FCd design technology can increase the filtration area by 20–80% by making use of the airbox’s contours.
