JT 520HDS 13/50 super-reinforced chain kit - ultra-light mud-resistant sprocket by JT DRIVE CHAIN (manufacturer reference: 485047). Designed for motocross use, this kit combines a reinforced HDS chain and an aluminum sprocket with a mud-resistant profile to meet the demands of muddy and rocky terrains.
- Chain: pitch 520, black/steel finish, type HDS reinforced with XS-Ring seals for better link sealing and extended lubrication.
- Sprocket: ultra-light aluminum, mud-resistant profile that facilitates dirt evacuation and limits accumulation on the sprocket.
- Configuration: 13-tooth sprocket / 50-tooth sprocket, suitable for gear ratio adjustments in all terrains.
- Usage: designed for load-bearing climbs and typical motocross stresses thanks to its reinforced construction.
Ideal for riders looking for a robust transmission without unnecessarily weighing down the rear of the motorcycle. The combination of reinforced chain + XS-Ring seals helps preserve link integrity and reduces frequent maintenance, especially in off-road conditions. Common compatibilities: YAMAHA YZ 250 F (CG40) 2021, YAMAHA YZ 250 FX (2020), and YAMAHA YZ 250 F (CG39) 2018.
