Manufacturer's ref: JTA210.48BLK — JT SPROCKETS ultra-light mud-resistant aluminum sprocket 210 - 520.
Designed for demanding motocross and roadster riders, this JT Sprockets rear sprocket combines lightness and strength. Machined from high-strength 7075‑T6 aluminum (Ergal), it features 48 teeth and is compatible with 520 pitch transmissions. Its lightweight construction reduces peripheral mass without compromising durability, making gear ratio changes easier.
The mud-resistant finish minimizes dirt buildup between the sprocket and chain, helping to keep the drivetrain cleaner during muddy outings. Ideal for replacement or modifying the gear ratio, it is particularly suitable for models such as BETA RR 480 4T (2024), HONDA CRF 450 X (2024), and HM MOTARD 450 (2013).
For optimal installation, check the spacing and mounting of your swingarm before installation and replace the chain if necessary to ensure even wear.
