Renthal Ultralight sprockets are a popular choice among professional and amateur racers who demand maximum performance and reliability. The advanced design significantly reduces rotational inertia, allowing the engine to rev more freely and the suspension to respond more effectively to terrain changes. Compatible with 520-pitch chains and designed as a direct replacement for stock sprockets on 2005-2022 KTM 250SXF models.
