EK/PBR 520MRD7 Chain Kit 13/51 - ultra-light sprocket: a drive system designed for motocross, where every gram and every link matters. This transmission combines a high-performance treated chain with an ultra-light aluminum sprocket to reduce inertia while maintaining good traction and abrasion resistance, suitable for the demanding conditions of competition.
Designed to minimize friction and wear in off-road conditions, this transmission line is aimed at riders seeking a balance between lightness and robustness: reinforced links, controlled slip, and a lightweight sprocket for increased responsiveness of the chassis. Ideal for 125 cc machines intended for motocross.
Compatible motorcycles (examples): KTM 125 XC (2026), GAS GAS MC 125 (2025), HUSQVARNA TC 125 (2024).
