RENTHAL 520R3 Reinforced Chain Kit 13/52 - Ultra-Light Mud-Resistant Sprocket (ref. 485386)
Specifically designed for motocross, this RENTHAL chain kit combines a reinforced 520 R3 chain with O-Ring seals and an ultra-light aluminum sprocket with a mud-resistant profile. Ideal for muddy terrains and the demands of off-road riding, it combines strength and lightness to maintain reliable transmission on challenging courses.
The O-Ring seals protect the links and retain lubrication, while the aluminum sprocket reduces unsprung weight and limits mud accumulation thanks to its specific design. With a sleek aesthetic featuring a gold/black finish, this kit gives your transmission a race-ready look.
