Features

EK/JT 520MRD7 Chain Kit 14/49 - Ultra-Light Sprocket

Specifically designed for motocross, this chain kit combines a high-performance EK chain with an ultra-light aluminum sprocket from JT. Engineered to withstand the demands of challenging terrains, it aims to minimize friction while providing good resistance to traction and abrasion. Gold/gold finish for a racing look that matches off-road motorcycles.

Compatibility: suitable for trail/cross, examples: YAMAHA YZ 250 (1987–1989).
Manufacturer reference: Not provided.
Sprocket configuration: 14/49 (front sprocket 14 teeth / rear sprocket 49 teeth).
Chain type: pitch 520, 114 links.
Color: Gold/Gold (chain and sprocket).
Sprocket: ultra-light aluminum — reduction of unsprung mass.
Indicative weight: 1.47 kg for 100 links.
Relative lifespan: 450 (value provided for 100 links).

Ideal for riders looking for a chain/sprocket set suited to the demands of motocross — regular maintenance and correct tension remain essential to ensure longevity and safety on track or off-road outings.
