Product details :

Features

The EK/JT 520MRD7 13/48 chain kit with ultra-light sprocket is designed for motocross riders seeking lightweight and reliability on demanding terrains. The gold chain (Gold/Gold) with a pitch of 520 combines a low weight with a construction aimed at minimizing friction without sacrificing tensile strength and abrasion resistance — essential qualities in motocross competition.

Configuration: 13 teeth front / 48 teeth rear (ultra-light aluminum sprocket)
Chain: 112 links, pitch 520, color Gold/Gold
Weight: 1.47 kg for 100 links
Relative lifespan: index 450 (for 100 links)
Sprocket material: ultra-light aluminum — mass reduction without compromising structural rigidity
Brand: EK CHAIN
Manufacturer reference: Not provided

Ideal for training and racing, this kit enhances acceleration and maneuverability by reducing unsprung mass. Lightweight and durable, the chain + aluminum sprocket combination is suitable for off-road demands, provided it is installed carefully and maintained regularly (tension checks, cleaning, and lubrication). Particularly suitable for both vintage and modern motocross machines.
