AFAM offers this 520XRR3 chain kit in a 13-50 configuration for the BETA RR 350cc, specially developed for off-road motorcycles subjected to high mechanical stress. Thanks to its reinforced X-Ring chain, it ensures smooth power transmission while minimizing friction and premature wear. Its ultra-light aluminum sprocket, featuring a mud-resistant design, reduces rotating mass and helps shed debris to maintain performance under the toughest conditions. The steel sprocket ensures excellent resistance to repeated stress and contributes to the longevity of the entire drivetrain. The 13-50 gear ratio prioritizes traction and sharp acceleration, a feature particularly valued in motocross and enduro. This kit offers a reliable solution for riders seeking to combine performance, durability, and efficiency on all terrains.
