Longer outer tubes increasing bushing overlap. A greater overlap reduces the radial force on the bushing resulting in lower level of friction under load. Öhlins RXF 48 S takes your ride to another level, and with the 2021 & 2022 updates you'll achieve faster lap times with smoother landings. With a refined micro finishing process applied to the TiN coating (Titanium-nitride) on the inner fork tuber, we've managed to reduce friction against both bushings and seals. Together with a new flex honing process of the inner tubes, the 2021 & 2022 version of the RXF 48 S gives you a better contact area on the main spring. No matter what track you're racing, our updated RXF 48 S fork will help you conquer your toughest ride yet.
