ProTaper 033191 Race Spec Aluminum Rear Sprocket Black Sprockets - 50T

The ProTaper 033191 Race Spec (RS) Aluminum Rear Sprocket is a precision-engineered motocross sprocket built from 7075-T6 heat-treated aluminum for the ultimate combination of lightweight performance and durability. Manufactured in the USA, this 50-tooth black anodized sprocket is designed to meet the demands of serious off-road and motocross riding.

Key Features:

• 7075-T6 heat-treated billet aluminum construction delivers exceptional strength with minimal weight
• Exclusive Angled Mud Groove design on every tooth allows the sprocket to self-clean during operation, preventing dirt buildup that leads to horsepower loss and accelerated wear
• 44% more tooth surface area compared to competing sprockets, dramatically extending sprocket life and improving chain contact
• Deep-penetrating hard anodized finish on black sprockets provides superior corrosion resistance and improved wear resistance
• Engineer-designed lightening window pattern achieves optimum balance of weight savings and structural strength, reducing unsprung rotating mass
• CNC machined edge chamfers eliminate sharp edges, reduce weight, and give a clean finished appearance
• Countersinks automatically center the sprocket to the hub during installation — no hub center guide needed
• Laser-etched tooth count for quick and easy identification
• Machined inlay for subsurface sticker location
• Made in the USA

The ProTaper Race Spec rear sprocket line is engineered to outlast the competition by combining advanced materials, precision manufacturing, and innovative self-cleaning geometry — making MPN 033191 the go-to choice for Kawasaki and Suzuki motocross and off-road riders who demand the best from their drivetrain components.
