AFAM offers this 520XRR3 chain kit in a 14-50 configuration designed for BETA RR 400cc motorcycles. It combines a reinforced X-Ring chain, a steel sprocket, and an Ultra-Light aluminum mud-resistant rear sprocket to optimize both mechanical strength and transmission responsiveness. X-Ring technology effectively retains internal lubrication, reducing friction and minimizing wear even during intensive use on abrasive terrain. The lightweight sprocket improves engine responsiveness by reducing rotating mass, which promotes sharper acceleration and greater handling precision. Its mud-resistant design facilitates the removal of debris to maintain consistent performance in wet, sandy, or muddy conditions. This kit offers a well-balanced solution for riders seeking performance, endurance, and consistency on all types of terrain.
