JT SPROCKETS Ultra-Light Aluminum Sprocket 853 - 520 (Manufacturer Ref: JTA853.49BLK)
Specifically designed for motocross, this JT Sprockets sprocket combines high-quality materials with precise machining. Made from 7075-T6 aluminum (Ergal), it features an ultra-light construction that remains resistant to the demands of the terrain while minimizing unsprung weight compared to a steel sprocket.
The careful finish helps to repel mud and dust, facilitating the removal of particles between the teeth and limiting clogging. Designed for easy installation as a direct replacement, this sprocket is aimed at riders looking to maintain the original gearing or slightly modify engine behavior by changing the number of teeth.
Common compatibilities: YAMAHA YZ 400 F (1998), YAMAHA WR 400 F (1998), YAMAHA YZ 250 (1998). Please check the chain pitch and fitment before ordering.
