SuperProx RFE-990-42-BLK Rear Steel Sprocket 42 Tooth for Husqvarna and KTM

The SuperProx RFE-990-42-BLK rear sprocket is designed to deliver exceptional durability and performance for both street and off-road motorcycling. Crafted from high-quality materials, this 42-tooth sprocket features a unique dual-material construction that optimizes longevity and efficiency. The steel teeth are engineered to last up to three times longer than traditional aluminum sprockets, providing increased wear resistance and reduced maintenance over time. The CNC-machined aluminum core, specifically made from 7075-T651 aluminum, ensures a lightweight design without compromising strength, making it ideal for demanding riding conditions. Larger tooth radius design reduces chain friction during operation, which helps extend chain life and improve overall drivetrain performance. This sprocket is U.S. and European patented, guaranteeing a precise fit and reliable operation for compatible Husqvarna and KTM models.
