Features

EK/PBR 520MRD7 12/50 Chain Kit - Standard Sprocket
Specifically designed for off-road practices, this EK CHAIN kit includes a 520 chain and a sprocket/crown pair in a standard 12/50 configuration. Designed for motocross bikes, it offers a complete solution to restore the transmission after a season on hard or muddy terrain.

Model Reference: 520MRD7
Configuration: 12-tooth sprocket / 50-tooth crown (standard)
Number of Links: 114
Pitch: 520
Color: gold / gold
Crown Material: steel
Weight: 1.47 kg for 100 links
Relative Lifespan: 450 (for 100 links, manufacturer data)

This kit is aimed at motocross riders looking for a transmission ready to withstand terrain stresses while facilitating maintenance and adjustments. The steel crown provides strength and wear resistance, and the 520MRD7 chain offers compatibility suitable for cross models, particularly on GAS GAS EC 125 RACING (2013–2015). Installation, tension adjustment, and regular lubrication remain essential to get the best performance from this kit.
