JT SPROCKETS ultra-light mud-resistant aluminum sprocket 822 - 520 (Manufacturer part number: JTA822.50BLK): a rear sprocket designed for demanding riders who seek lightweight and grip in muddy or road conditions. Made from aerospace-grade 7075-T6 aluminum (Ergal), it combines low weight and good mechanical strength, while maintaining a profile suitable for quad, motocross, and roadster uses.
The "mud-resistant" finish facilitates the ejection of particles and limits accumulation on the teeth, making it practical for enduro and off-road outings. Its ultra-light design reduces unsprung weight for a more responsive feel at the handlebars without compromising compatibility with your 520 drivetrain. Direct mount as a standard replacement.
Compatible with machines such as GAS GAS EC 200 RACING (2020), BETA RR 480 4T ENDURO EFI (2019), or HM CRE 125 COMP SIX (2015) depending on gearing and installation. Check the bolt pattern and mounting before purchase to ensure fitment on your motorcycle/quad.
