Description
This 51-tooth rear sprocket in Black carries ProTaper’s Race Spec tooth profile onto Honda bikes, aimed at riders who want gearing precision without sacrificing chain life.
This is ProTaper’s Race Spec (RS) rear sprocket line, the same design philosophy that shows up across their pro-level drivetrain parts. The signature Angled Mud Groove cut into the tooth face throws off mud in real time, so the drivetrain keeps working even when the track turns to soup. CNC precision shapes each tooth for a contact patch that runs up to 40 percent larger than competing sprockets, cutting down on the wear that comes from a smaller footprint.
Features and Benefits
- Countersunk bolt holes self-center the sprocket to the hub on install, no separate hub center guide needed
- Each tooth clears itself of mud on the fly thanks to the Angled Mud Groove, protecting chain and sprocket life
- Tight CNC tolerances give this sprocket up to 40 percent more usable tooth surface than competing designs
- Cut to 51 teeth for Honda rear hubs, finished in Black, part of ProTaper’s Race Spec lineup
Why buy ProTaper from IPD Racing?
IPD Racing has been building and racing performance machines since 2005, and we only stock parts we would run on our own bikes. ProTaper sprockets are a mainstay in our shop for exactly this reason, and every order ships from a stocking warehouse so you are not waiting on a dropship supplier.
This 51-tooth sprocket is sized for Honda rear ends specifically, so double check your current gearing before ordering if you are stepping up or down from stock. Part number 033250.
