AFAM offers the reinforced 520XRR3 14/49 chain kit with an ultra-light, mud-resistant sprocket—a complete solution designed for motocross and enduro motorcycles subjected to extreme conditions. This kit combines a reinforced chain featuring X-Ring technology, a standard steel sprocket, and a lightweight aluminum rear sprocket designed to reduce clogging by limiting the buildup of mud and debris. The X-Ring chain reduces internal friction while maintaining effective lubrication, which improves the assembly’s longevity even under intensive use. The ultra-light sprocket helps reduce rotating mass, resulting in better engine responsiveness and sharper acceleration on technical terrain. The system ensures smooth and reliable power delivery, which is essential for maintaining traction and control in challenging conditions. This kit offers a balanced combination of performance, durability, and ease of maintenance for demanding riders.
