AFAM offers the reinforced 520XRR3 14/49 chain kit with an ultra-light mud-resistant sprocket for the BETA RR 200cc and BETA RR 250cc—a complete solution designed for enduro and motocross motorcycles subjected to high stress. This kit combines a reinforced chain featuring X-Ring technology, a standard 14-tooth steel sprocket, and a 49-tooth aluminum chainring specially developed to facilitate the removal of mud, sand, and debris. The sprocket’s lightweight design reduces rotating mass, thereby improving drivetrain responsiveness and the feel of acceleration. The X-Ring seals help minimize chain wear and stretch, ensuring reliable operation and an extended service life even under heavy use. Its reinforced design ensures precise power transfer while maintaining excellent resistance to off-road stresses. Thanks to its balance of lightness, durability, and efficiency, this kit is an ideal choice for riders seeking long-lasting performance on the most demanding terrain.
