ProTaper 49-Tooth Rear Blue Sprocket, Model RS, Part Number 033219

Race Spec (RS) Rear Sprockets feature our revolutionary Angled Mud Groove. This exclusive design creates a self-cleaning effect during operation, shedding away mud that would otherwise lead to horsepower loss and sprocket wear. With their precise CNC machining and unique layout, these grooves also allow an increase in tooth surface area of up to 40% over competing sprockets. As a result, contact with the chain is significantly improved, leading to a marked increase in sprocket life over other brands. That's the ProTaper difference.

• Countersinks automatically center sprocket to hub during installation, no hub center guide needed
• Deep penetrating anodized finish protects from corrosion and improves wear resistance
• Exclusive mud-groove design on both sides of every tooth
• Precision CNC-machined to the strictest tolerances
• 7075-T6 heat-treated billet aluminum
• Made in USA

The ProTaper Race Spec (RS) rear sprocket is a 49-tooth blue sprocket designed for select Honda and Yamaha powersports applications. Its Angled Mud Groove design creates a self-cleaning effect during operation, helping shed mud that can contribute to horsepower loss and sprocket wear. The groove layout also increases tooth surface area by up to 40% over competing sprockets, improving chain contact and promoting extended sprocket life.

Countersinks automatically center the sprocket to the hub during installation, eliminating the need for a hub center guide. Precision CNC machining delivers tight tolerances, while the deep penetrating anodized finish helps protect against corrosion and improves wear resistance. The sprocket is made from 7075-T6 heat-treated billet aluminum and is made in the USA.
