Pro Taper – Race Spec MX Aluminum Rear Sprocket (KTM)

The Pro Taper Race Spec MX Aluminum Rear Sprocket (KTM) uses 7075-T6 heat-treated billet aluminum, precision CNC machining, and Pro Taper’s angled mud-groove design. The result is a lightweight rear sprocket built to shed debris and maintain strong chain contact in off-road conditions.

Why We Like It

The combination of lightweight 7075-T6 aluminum, precise machining, and mud-shedding tooth-area design makes sense for riders who want performance without giving up durability.

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 rear sprockets by motorcycle or ATV fitment and tooth count.
