Description
Designed and built by race engineers in the TST WORX race program, our Lightweight Aluminum Rear Sprocket was developed with the harshest riding conditions in mind. Our use of the best materials and manufacturing procedures ensure practical longevity while maximizing weight loss for increased performance and power delivery. The blend of high-quality material, advanced hardening procedures, lightweight design, proprietary tooth profile, and ultra-smooth tooth transitions ensure exceptional performance even during the most demanding riding situations.
We produce every TST WORX Rear Sprocket from 7075-T6 aluminum alloy. This high-quality material is CNC machined using a propriety holding plate process developed to eliminate vibration during the machining process and ensuring extreme precision and material integrity. We then treat the entire rear sprocket with a matte black Type III hard coat anodizing process that penetrates the aluminum and builds an ultra-hard surface layer, resulting in a light weight sprocket with exceptional durability characteristics capable of taking on the rigorous demands of the street and track. It's time to give your Kawasaki the sprocket and performance it deserves.
