Features

EK/PBR 520MRD7 Chain Kit 14/50 - Ultra-Light Sprocket

This EK CHAIN 520MRD7 chain kit is designed for motocross riders looking for a lightweight and cohesive set for their transmission. The package includes a 14-tooth front sprocket and a 50-tooth rear sprocket made of "ultra-light" aluminum, paired with a 520 chain of 112 links with a double-sided gold coating (Gold/Gold).

Pitch: 520
Number of links: 112
Color: Gold / Gold (chain and rivets)
Sprocket material: Ultra-light aluminum
Weight: 1.47 kg / 100 links → ≈ 1.65 kg for 112 links
Relative lifespan: 450 (for 100 links)

The aluminum sprocket combination reduces unsprung mass, while the 520 chain is suitable for typical off-road demands. The gold treatment provides a neat finish and facilitates visual maintenance. This kit is suitable for motocross configurations, particularly for models like the KAWASAKI KX 250 (KX250D) 1985 - 250 cc.

Manufacturer reference: Not disclosed.
