AFAM offers the standard 520MR2 11/42 chain kit with a hard-anodized ultra-light sprocket—a complete solution designed to ensure smooth and reliable power transfer. Consisting of a high-quality chain, a steel sprocket, and a lightweight aluminum chainring, this kit allows you to replace all transmission components in a single installation. The sprocket’s ultra-light design helps reduce rotating mass, thereby improving the motorcycle’s responsiveness during acceleration and changes in pace. Its hard-anodized finish enhances resistance to wear and the mechanical stresses encountered during intensive use. The assembly ensures smooth drivetrain operation while contributing to the longevity of the components. This kit is an ideal choice for riders seeking a high-performance, durable drivetrain suited to the demands of motocross or enduro riding.
