EK CHAIN 520M3 chain kit in 14/48 configuration, specially sized for motocross bikes. This kit includes a 520 pitch chain with 112 links and an ultra-light aluminum sprocket (48 teeth) paired with a 14-tooth pinion — all presented in a Gold/Gold finish for a sleek look on the drivetrain.
Designed for the motocross environment, this kit is aimed at riders looking for a complete pinion/sprocket/chain setup ready to install. The aluminum sprocket lightens the rolling stock and facilitates gear ratio tuning, while the 520 format remains a reliable standard for many off-road displacements. Suitable particularly for YAMAHA YZ 450 F (CJ03/CJ05) models.
Check the number of links and the 14/48 ratio before installation for a precise fit on your motorcycle, and ensure proper tension and lubrication according to the terrain being used.
