AFAM offers the reinforced 520XRR3 15/48 chain kit with an ultra-light, mud-resistant sprocket for the BETA XTRAINER 300cc—a complete solution designed for enduro and motocross motorcycles operating in particularly demanding environments. This kit combines a reinforced chain featuring X-Ring technology, a steel sprocket, and a lightweight aluminum chainring designed to minimize mud buildup and improve debris clearance. X-Ring technology reduces internal friction while maintaining optimal lubrication, which helps extend the drivetrain’s service life even under heavy use. The ultra-light sprocket reduces rotating mass, improving engine responsiveness and acceleration on technical terrain. The system ensures smooth and efficient power transfer, which is essential for maintaining control and traction in the most challenging conditions. This kit offers a balanced combination of performance, durability, and ease of maintenance for demanding drivers.
