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 40-tooth replacement sprocket designed for select KTM and Husqvarna powersports applications. Manufacturer part number: 033290. Vendor part number: 651264. It fits 2014–2019 KTM 50 SX models and 2017–2020 Husqvarna TC50 models.

Constructed from 7075-T6 heat-treated billet aluminum, this black sprocket is precision CNC-machined to strict tolerances. Its exclusive angled mud-groove design on both sides of every tooth 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 contributing to extended sprocket life.

Countersinks automatically center the sprocket to the hub during installation, eliminating the need for a hub center guide. A deep-penetrating anodized finish helps protect against corrosion and improves wear resistance. The ProTaper Race Spec rear sprocket is made in the USA.
