Taper – Race Spec Front Countershaft Sprocket (Yamaha)
The Pro Taper Race Spec Front Countershaft Sprocket (Yamaha) is built for application-specific drivetrain fitment, using CNC machining and internal broaching in case-hardened, core-refined chromoly steel. The design focuses on precise countershaft fit, strength, reduced chain drag, and wear resistance.
Why We Like It
It keeps the important drivetrain details in focus: precise machining, strong steel construction, accurate chain engagement, and a compact rotating component.
Why It Works For You
With the correct application and tooth count, the sprocket can maintain proper chain alignment and dependable power transfer. Fitment must match the motorcycle or ATV. Compare more front countershaft sprockets by motorcycle fitment and tooth count.
Fitment Notes
