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.

Very good business principles and products. Instruction videos on Youtube are very straight forward and demonstrative.
Everything is amazing quality and was packaged very nicely!
Everything was perfect fitment, looks, and function. Recomened
Perfect fit, installed onto 2021 Z400, difficult installation due to Kawasaki engineering, not TST.
Easy install and looks awesome
Solid set of dual-point frame sliders on my 2026 MT-09 SP. Build quality is excellent with sturdy materials and a clean finish that looks great on the bike. Installation was straightforward with clear fitment and no issues lining everything up. Definitely a quality upgrade that adds protection without taking away from the bike’s overall look.
Super easy install and to match my new integrated taillight with TST industries. MUCH BRIGHTER than the stock 500 bulbs for sure so I do feel a bit safer people can see me more. 100% would recommend buying and they look cool.
TST made it so easy to install with the YouTube videos and the sequential turn signals are sick. The LEDs and also very bright compared to the stock taillight and you get extra modes with what style you like. I would definitely recommend and ride safe everyone.
It's hard to explain how good this looks on the bike. It's clean, highly visible and looks like it came from the factory. If you're thinking about it, get it.
Looks sweet. I am going to buy one. But my question is where does the license plate light go? Your site is trying to pair my purchase up with a license plate light? Would like to know where that goes if I have the adjustable high mount?
This really added a layer of protection that is functional and aesthetically pleasing 👌. The install was super easy on my 2006 honda cbr600rr.
