ProTaper 033219 Race Spec Rear Sprocket Blue 49 Teeth Honda Yamaha

The ProTaper 033219 Race Spec (RS) Rear Sprocket is a premium 49-tooth blue anodized rear sprocket engineered for Honda and Yamaha motocross and off-road applications. Built from heat-treated 7075-T6 billet aluminum and precision CNC machined to the strictest tolerances, this sprocket delivers the ideal balance of lightweight performance and exceptional durability.

Key Features:

• 7075-T6 Heat-Treated Billet Aluminum construction for maximum strength at minimal weight
• Exclusive Angled Mud Groove design on both sides of every tooth creates a self-cleaning effect during operation, preventing dirt and mud buildup that leads to horsepower loss and accelerated wear
• Up to 40% more tooth surface area over competing sprockets thanks to precision CNC-machined groove layout, resulting in significantly improved chain contact and longer sprocket life
• Deep-penetrating anodized finish in blue provides corrosion protection and improved wear resistance
• Engineered window pattern reduces unsprung rotating mass without sacrificing structural integrity
• Machined edge chamfers eliminate sharp edges, reduce weight, and deliver a clean race-ready appearance
• Countersink bolt holes automatically center the sprocket to the hub during installation — no hub center guide required
• Laser-etched tooth count for easy field identification
• Made in USA

The ProTaper Race Spec RS series is the choice of serious motocross and off-road racers who demand a sprocket that outperforms and outlasts the competition. With 49 teeth and a blue anodized finish, this sprocket is a direct-fit replacement for compatible Honda and Yamaha models.
