EK/PBR 520M3 13/51 chain kit with ultra-light sprocket, designed for motocross requirements. This kit combines the robustness of a high-performance 520 chain with a lightweight aluminum sprocket to reduce unsprung mass and promote a more responsive acceleration on rough terrains.
Designed for motocross and recreational competition use, this kit emphasizes resistance to tension and abrasion while minimizing friction. The gold finish adds a racing touch and facilitates visual wear monitoring. Compatible with 520 transmission models, it is particularly suitable for KTM 300 XC TPI (2020-2021).
Delivered in a ready-to-install configuration, it is aimed at riders looking for a lightweight, durable set suitable for the extreme demands of the terrain. Manufacturer reference: not provided.
