AFAM offers this 520XRR3 chain kit in a 13-50 configuration for the BETA RR 350cc, designed to meet the demands of motocross and enduro riders seeking a drivetrain that is both high-performance and durable. Comprising a reinforced X-Ring chain, a steel sprocket, and an ultra-light, mud-resistant aluminum rear sprocket, it ensures excellent power transmission while minimizing friction losses. The lightweight sprocket reduces rotating mass to improve the bike’s responsiveness, while its mud-shedding profile facilitates the removal of dirt, sand, and debris. The XRR3 chain ensures long-lasting lubrication of the pins and rollers, which helps reduce wear and extend the assembly’s service life. The 13-50 gear ratio promotes optimal traction and crisp acceleration, making it particularly well-suited for technical trails and rough terrain. This kit is an ideal solution for riders seeking to combine reliability, precise handling, and consistent performance in off-road riding.
