EK/PBR 520MRD7 13/48 Chain Kit – Ultra-Light Sprocket
Designed for the demands of motocross riding, this EK CHAIN kit combines a high-performance 520 chain with an ultra-light aluminum rear sprocket. Ideal for those seeking a compact, lightweight, and visually appealing transmission (Gold/Gold color), it is intended for motocross bikes and intensive use in competition or training.
The chain is designed to minimize friction while providing good resistance to tension and abrasion on various terrains (dirt, rock, mud). The aluminum sprocket reduces unsprung inertia for a more responsive throttle response, without compromising strength suitable for off-road conditions.
Common compatibilities: FANTIC XX 125 (2022), YAMAHA YZ 125 (CE16) (2021), FANTIC XE 125 (2022). Check the number of links and the sprocket/sprocket ratio for a precise fit on your machine.
