Product details :

Features

The EK/JT 520MRD7 14/50 chain kit is designed for demanding motocross riders: a 520 MRD7 chain paired with a 14-tooth sprocket and an ultra-light 50-tooth aluminum rear sprocket. Engineered to minimize friction while providing high resistance to traction and abrasion, this kit is suitable for transmissions subjected to the severe conditions of competitive terrains.

Brand: EK CHAIN
Manufacturer Reference: Not provided
Composition: 520 MRD7 chain + 14-tooth sprocket / 50 aluminum sprocket (ultra-light)
Number of Links: 114
Pitch: 520
Color: gold finish (chain & sprocket)
Weight: 1.47 kg for 100 links
Relative Lifespan: 450 (index for 100 links)

Ideal for strong traction in off-road conditions, this kit is suitable for motocross machines requiring a reliable and lightweight transmission. Compatible with models such as the YAMAHA YZ 250 (1998 - 250 cc), it easily integrates into a competition-oriented drivetrain. Be sure to check the installation and recommended tension for your machine before the first ride.
