Countershaft Front Sprocket

Durable gearing starts at the countershaft. The JT Sprockets Countershaft Front Sprocket is designed to deliver consistent drive and dependable wear life in demanding riding conditions. Manufactured from SCM420 chromoly steel alloy, it’s built to handle repeated load cycles while keeping your drivetrain running smoothly.

If your current front sprocket is hooked, noisy, or causing accelerated chain wear, replacing it restores clean engagement and helps protect the rest of your final drive components. This model is configured for a 520 chain and features a 12-tooth count—ideal when you need the correct fitment and gearing for your setup.
