The JT Sprockets JTA798.52BLK sprocket is a part dedicated to motocross riders seeking lightweight and durability for their transmission. Machined from aerospace-grade 7075-T6 aluminum (Ergal), this ultra-light sprocket is designed to reduce unsprung weight without compromising strength. Its "mud-resistant" finish facilitates the removal of particles and limits mud accumulation between the chain and the wheel, an advantage on muddy or sandy terrains.
Designed for motocross bikes, this sprocket is compatible with YAMAHA YZ 85 models (references CB09, CB10) and other machines compatible with the 428 pitch. Its machining reduces mass without adding weight to the transmission, making it easier to handle the machine and perform regular chain maintenance. Ideal for riders who spend time on loose terrain and want a reliable part that is easy to install and maintain.
