Features

EK/JT 520H 12/50 Chain Kit - Ultra-Light Sprocket
Designed for off-road, this chain kit combines EK's renowned quality with an ultra-light aluminum sprocket. Ideal for motocross riders seeking a reliable and lightweight transmission solution, it features the standard pitch 520 and a length of 112 links to fit common off-road setups.

Sprocket / Sprocket: 12/50 (ratio suitable for motocross)
Pitch: 520
Number of links: 112
Sprocket material: aluminum (ultra-light)
Chain color: steel / steel
Weight: 1.66 kg for 100 links
Relative lifespan: 150 (reference given for 100 links)

This kit offers a good compromise between reduced weight and robustness to tackle muddy paddocks and repeated jumps. It is particularly suitable for lightweight motocross and enduro setups — compatible motorcycles include the Yamaha YZ 125 (1984 and 1985 models) when the pitch and length match. Be sure to check the length and tension adjustment during installation and regularly maintain the chain and sprocket to maximize lifespan.
