Sharpen the response of your KTM 125 SMC R with the DNA Performance Air Filter
developed to improve intake flow and support more consistent engine behaviour. By reducing the restriction caused by the standard paper filter, this upgrade helps the engine breathe more freely and operate more efficiently during everyday riding and aggressive use alike.
Using DNA’s Full Contour Design to maximise the working surface of the filter, airflow is guided evenly across the element rather than being concentrated in limited areas. This leads to steadier throttle feel, improved control at low speeds and a more responsive ride when opening the throttle. The reusable cotton construction also means this filter is designed to last rather than be replaced.

FAQ
Can I fit the filter without oiling it?
No. DNA filters must always be oiled before use. The oil is essential to trap fine particles and protect the engine. Reapply oil after each clean.
