The JT Sprockets JTA1793.45BLK sprocket is a transmission part designed for roadsters seeking a reliable replacement or a new gear ratio. Made from high-strength 7075-T6 aluminum (Ergal), this "ultra-light" sprocket reduces the mass of the transmission compared to steel parts while maintaining a standard tooth geometry.
Designed for easy integration with the final drive (sprocket + chain), this sprocket offers a lightweight solution to adjust the gear ratio and engine behavior without modifying the sprocket. Its tooth profile is machined for precise engagement with 520 chains, allowing for simple installation on compatible hubs.
