The ProTaper KTM 85 SX (17/14) Rear Aluminum Sprocket - 49 Teeth - Orange is a 49-tooth rear sprocket built from heat-treated 7075-T6 billet aluminum and CNC-machined in the USA for the KTM 85 SX and a range of other small-bore two-strokes. ProTaper's Race Spec series puts angled mud grooves on both sides of every tooth, which sheds mud during riding and increases tooth surface area by up to 40% compared to competing sprockets, extending sprocket life through better chain contact. Built-in countersinks self-center the sprocket on the hub at installation, so no separate hub center guide is needed. The deep anodized orange finish resists corrosion and adds durability against everyday wear.
A larger rear sprocket like this 49-tooth option lowers overall gearing, which sharpens off-the-line acceleration and punch out of corners at the cost of some top-end speed.
