Product Overview
The Sunstar Powerdrive Steel Front Countershaft Sprocket (Part #33213) is a premium, high-strength replacement engine gear manufactured by Sunstar, a leading supplier of original equipment (OEM) sprockets trusted by major motorcycle builders worldwide. This 13-tooth front sprocket anchors your motorcycle's primary drive system, transferring mechanical engine power directly from the transmission countershaft to the rear wheel assembly via an industry-standard 520-pitch drive chain. Engineered to exceed strict factory quality guidelines, this sprocket serves as a highly precise bolt-on replacement or custom gearing option to optimize low-end torque and off-the-line acceleration.
