Vortex 249ZB-43 520 Aluminum Rear Sprocket 43 Tooth Black Hardcoat

The Vortex 249ZB-43 is a high-performance 520-pitch aluminum rear sprocket designed for serious motorcycle enthusiasts who demand both light weight and exceptional durability. Featuring 43 teeth and Vortex's advanced F5 Black Hardcoat PTFE finish, this sprocket delivers significant weight reduction over stock steel sprockets while maintaining impressive longevity.

Key Features:

• 100% CNC machined in the USA from 7075-T6 billet aluminum for maximum strength and minimal weight
• F5 PTFE (Polytetrafluoroethylene) black hardcoat finish applied after machining for superior wear resistance
• Proven to last up to 30% longer than standard aluminum sprockets
• Vortex patented saber tooth groove design reduces friction and extends sprocket life
• Lower coefficient of friction than raw aluminum for reduced drivetrain power loss
• Unique self-cleaning tooth profile helps prevent mud and debris buildup
• 520 chain pitch with 43 teeth for precise gearing options
• Heat-resistant coating withstands high-performance riding conditions

The PTFE coating is applied after the sprocket is cut, allowing the coating to bond directly to the teeth for enhanced lubricity and wear resistance. This manufacturing process results in a sprocket that stays cleaner, runs cooler, and outlasts traditional anodized aluminum sprockets. Ideal for street, track, and racing applications where every ounce of rotating mass matters.
