RENTHAL 520R1 Chain Kit 13/49 - Ultra-light Mud-resistant Sprocket (Manufacturer part number: 487521): a kit designed for motocross riders who want a lightweight and easy-to-maintain setup. This kit combines the RENTHAL R1 chain with a 520 pitch and an ultra-light aluminum sprocket with a mud-resistant profile, optimized to limit mud accumulation between the teeth during off-road rides.
The kit is aimed at riders on soft and muddy terrains looking for a lightweight solution without compromising the original assembly. The gold/black finish of the chain adds a striking aesthetic touch to the rear wheel, while the aluminum sprocket reduces unsprung weight. Standard mounting with 13 teeth on the pinion / 49 teeth on the sprocket, adaptable to many off-road machines.
Notable compatibility: HONDA CRF 250 R (ME12) 2018 - 250 cc. Please check the pitch and mounting before installation to confirm compatibility with your model.
