At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket, 41-Tooth, 520 Pitch, Silver (Part #120A-41) — a race-bred aluminum sprocket built for Ducati riders who demand strength without the weight penalty of steel. Known throughout the paddock as the industry standard, this CAT5 sprocket is precision CNC machined from aerospace-grade 7075 aluminum, giving you a component that shaves rotating mass off your rear wheel while standing up to the abuse of hard riding and racing. The reduced rotating weight helps improve acceleration and handling response, letting your Ducati change direction and pick up speed with less effort from the drivetrain.

This particular sprocket is set up for a 520 chain conversion with 41 teeth, finished in a durable silver anodized coating that resists corrosion and keeps the sprocket looking sharp under track and street conditions alike. Vortex backs this design with a patented tooth geometry that isn't found on any other sprocket on the market, engineered specifically to extend service life while maintaining smooth, consistent chain engagement.

Features:

• CNC machined from 7075 aluminum for amazing strength and light weight
• Unique, patented Vortex tooth design increases sprocket longevity and is unlike any other sprocket on the market
