EK/PBR 520M3 Chain Kit 13/48 - Ultra-light Sprocket by EK CHAIN, designed for motocross practices. This kit combines a high-quality 520 chain with an ultra-lightweight aluminum rear sprocket, reducing unsprung mass and maintaining optimal responsiveness during acceleration and gear changes on trails or in competition.
Designed to withstand the demands of off-road riding — jumps, landings, mud, and rocks — this kit prioritizes abrasion resistance while minimizing friction for precise power transfer. The gold finish adds an aesthetic touch and facilitates visual wear monitoring. Ideal for motocross riders seeking lightweight and reliable performance during starts and accelerations.
Exemplary compatibility with models such as the HONDA CRF 150 F (KE01) 2003-2005; check the adjustment and tension of the final drive during installation to ensure safety and longevity.
