Features

EK/PBR 520MRD7 13/49 Chain Kit - Ultra-Light Sprocket

Designed for motocross riders seeking a complete, reliable, and lightweight chain kit, this setup combines the EK 520MRD7 chain with a 13-tooth sprocket and a 49-tooth ultra-light aluminum rear sprocket. The gold/gold visual finish complements racing machines and facilitates identification during maintenance checks.

Configuration: 520MRD7 chain – 116 links, 13-tooth sprocket, 49-tooth sprocket (ultra-light)
Color: Gold / Gold
Pitch: 520
Weight: 1.47 kg for 100 links (manufacturer reference)
Relative lifespan: 450 (reference for 100 links)
Sprocket material: aluminum to reduce unsprung mass

Ideal for amateur motocross/competition use, this kit prioritizes friction reduction and the lightweight nature of the sprocket to enhance transmission responsiveness without claiming unverified performance. Standard installation and adjustment: check alignment, tension, and lubricate regularly to maintain longevity.

Compatibility types: possible mounting examples — GAS GAS ENDUCROSS 250 (1996 - 250 cc).
