Description

When it comes to increasing the power delivery of the mighty Honda 125cc engine, the rear sprocket is a great place to start. By upgrading to a lightweight aluminum sprocket, you're able to decrease parasitic power loss in the drive train. With a roughly 65% decrease in the weight of the sprocket, that means it takes less power to turn and therefore transfers more of that power to the rear wheel. That may not seem like a huge deal on a standard bike, but when it comes to the Honda Grom, Monkey, or Super Cub 125, every bit of power that you can get to the wheel counts and makes a difference. 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 6061 aluminum alloy. This high-quality material is CNC machined using a propriety holding plate process developed to eliminate vibration during the machining process and ensure 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 lightweight sprocket with exceptional durability characteristics capable of taking on the rigorous demands of the street and track.

Be sure to check the "Specs" tab for even more info on tooth count, sprocket weight, and fitment.
