Product details :

Features

EK/JT 520MRD7 14/48 Chain Kit - ultra-light sprocket by EK CHAIN: a set designed for motocross riders looking for a lightweight and precise replacement for their bike's transmission. Composed of the 520 chain and a 14-tooth sprocket paired with a 48-tooth "ultra-light" aluminum sprocket, this kit combines performance and aesthetics with a gold finish on the chain.

Usage: Motocross / competition
Pitch: 520
Number of links: 112 (to be adjusted during installation)
Color: Gold / Gold
Sprocket: Ultra-light aluminum
Weight: 1.47 kg for 100 links (reference)
Relative durability index: 450 (for 100 links, manufacturer data)

Designed to withstand the specific demands of off-road riding, this kit facilitates acceleration while reducing unsprung mass thanks to the aluminum sprocket. The gold finish adds a racing visual touch to your swingarm. Suitable for motocross models such as the YAMAHA WR 250 Z (1998 - 250 cc); check the exact compatibility with your machine before installation.

Biker tip: check the chain tension and perform regular lubrication/checks after muddy rides to preserve the lifespan of the entire set.
