JT 520HDS 13/49 Super Reinforced Chain Kit — the transmission pack designed for off-road use. Developed by JT Drive Chain for motocross, this kit combines a reinforced HDS chain in black/steel and an ultra-light aluminum sprocket with a mud-repellent profile. Ideal for riders seeking durability and weight savings without compromising reliability.
- Chain Type: JT HDS, pitch 520, black/steel finish
- Seals: XS-Ring for improved sealing and better lubricant retention
- Sprocket: Ultra-light aluminum with a mud-repellent profile
- Quality: Super reinforced, suitable for off-road demands
- Tooth Count: 13/49 (sprocket/sprocket)
The combination of the HDS chain and XS-Ring seals minimizes premature wear by keeping grease between the links, while the aluminum sprocket reduces unsprung mass for a livelier machine behavior. The mud-repellent profile facilitates dirt evacuation during muddy and sandy outings.
Main compatibilities: FANTIC XXF 450 (2026), YAMAHA YZ 450 F (CJ23) 2021, YAMAHA YZ 450 FX (2020). Always check the recommended sprocket/sprocket ratio for your model before installation.
