Features

EK/JT 520M3 Chain Kit 14/50 - Ultra-Light Sprocket

Designed for demanding motocross riders, this EK/JT 520M3 chain kit combines a high-performance chain with an ultra-lightweight aluminum rear sprocket. The construction aims to reduce friction while maintaining high resistance to tension and abrasion, to withstand the stresses of the terrain and competitive outings.

Type: Complete chain kit 14/50 (sprocket/sprocket + chain)
Pitch: 520
Number of links: 114
Color: Gold/Gold (finishes)
Sprocket Material: Ultra-light aluminum
Relative lifespan (100 links): 450
Stated weight: 1.36 kg / 100 links

The aluminum sprocket reduces unsprung weight for quicker inertia changes, while the treated chain minimizes wear in muddy and abrasive motocross conditions. Installation and maintenance remain accessible for those who master the adjustment of the tensioner and the correct tension.

Common compatibilities:

FANTIC XX 250 (2026 - 250 cm3)
YAMAHA YZ 250 (CG23) (2021 - 250 cm3)
YAMAHA YZ 250 X (2020 - 250 cm3)
