RENTHAL 520R1 Chain Kit 13/49 - ultra-light mud-resistant sprocket: a drivetrain designed for motocross, combining lightweight and clearance to tackle muddy terrains. This kit includes an R1 chain with a 520 pitch in gold/black and an aluminum sprocket with an "ultra-light" profile specially machined to limit mud accumulation between the teeth.
Designed for motocross riders who want a reliable and easy-to-maintain setup: the aluminum sprocket reduces unsprung mass, and its machining facilitates the removal of dirt and mud on slippery tracks. The R1 chain without links is suitable for configurations where simplicity and compatibility with a wide range of 520 transmissions are desired.
Common compatibilities: particularly suitable for Kawasaki KX 250 (KX250R 2005, KX250M 2004, KX250L 2002) — check the ratio and pitch before installation.
