Features

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

Specifically developed for motocross, this chain kit combines a high-performance chain and an ultra-light aluminum sprocket. The 520MRD7 construction targets friction reduction while maintaining good tensile strength and abrasion resistance, suitable for the repeated stresses of rough terrains and competition sessions.

Color: Gold/Gold for chain and seals
Pitch: 520
Gear/Sprocket Configuration: 14/50
Number of Links: 114
Sprocket Material: Ultra-light Aluminum
Declared Weight: 1.47 kg / 100 links
Relative Lifespan (for 100 links): 450

Ideal for riders looking for a lightweight setup without sacrificing mechanical strength. The gold finish facilitates visual inspection and wear prevention. Regular maintenance (cleaning and lubrication) is required to ensure longevity and reliability on the track.

Common compatibilities: YAMAHA YZ 250 (2021), YAMAHA YZ 250 X (2020), and YAMAHA WR 250 F (2020) — will fit many 250cc models requiring a 14/50 ratio in 520.
