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.\n\u003cul\u003e\n  \u003cli\u003eCountersinks automatically center sprocket to hub during installation, no hub center guide needed\u003c\/li\u003e\n  \u003cli\u003eDeep penetrating anodized finish protects from corrosion and improves wear resistance\u003c\/li\u003e\n  \u003cli\u003eExclusive mud-groove design on both sides of every tooth\u003c\/li\u003e\n  \u003cli\u003ePrecision CNC-machined to the strictest tolerances\u003c\/li\u003e\n  \u003cli\u003e7075-T6 heat-treated billet aluminum\u003c\/li\u003e\n  \u003cli\u003eMade in USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe ProTaper Race Spec rear sprocket is a 42-tooth black sprocket designed for KTM 50 SX applications from 2009 through 2013.
