AFAM offers this 520XRR3 chain kit in a 13-50 configuration, specially developed for enduro and motocross motorcycles riding on demanding terrain. It combines a reinforced X-Ring chain, a steel sprocket, and an Ultra-Light mud-resistant aluminum rear sprocket to ensure reliable and consistent power transmission. X-Ring technology reduces internal friction while maintaining long-lasting lubrication, thereby limiting component wear. Thanks to its lightweight sprocket and mud-resistant profile, this kit enhances drivetrain responsiveness while effectively shedding mud, sand, and debris. The 13-50 gear ratio improves traction and low-RPM acceleration, a benefit particularly appreciated on technical sections. This kit is an ideal solution for riders seeking to combine performance, light weight, and durability during intensive off-road use.
