Product details :

Features

Designed for the demands of off-road riding, the EK/JT 520MRD7 13/49 Chain Kit - ultra-light sprocket provides a balance between strength and lightness. Intended for motocross, this kit combines a treated gold-colored chain and an ultra-light aluminum sprocket to minimize unsprung mass and optimize the motorcycle's responsiveness without making unproven technical claims.

Brand: EK CHAIN
Type: 520 Chain Kit (sprocket 13 / sprocket 49)
Number of links: 112
Pitch: 520
Color: Gold / Gold
Sprocket material: Aluminum (ultra-light)
Weight: 1.47 kg (for 100 links)
Relative lifespan: 450 (based on 100 links)

This kit meets the expectations of motocross riders who want a lightweight and high-performance transmission for acceleration and directional changes. The aluminum sprocket reduces unsprung mass while the 520 chain provides the necessary strength to withstand the traction and abrasion forces typical of off-road terrain. Compatible with motocross models such as the YAMAHA YZ 125 (1988), this kit is aimed at riders seeking reliability and stability during intensive sessions.
