Dirt Bike Sprockets and Chains

A couple wear and tear parts that every rider should be most cautious about are the front and rear sprockets, and the chain. The sprockets are the easiest ones to pin point the wear and tear on as the teeth will be rounded, worn down, or damaged. Damages to the rear sprocket such as the ones listed can cause major issues with your chain and eventually deteriorate it to the point of breaking. Sprockets are one of the easiest ways to tune your bikes power delivery without messing around with the engine. Whether you are looking to add more acceleration on a tight and technical track, or more top speed to fly through the desert, changing a couple teeth on your sprockets can resolve your troubles.


A rule of thumb to go by when changing sprockets is for every 1 tooth you change on the front, it is like changing 3-4 teeth on the rear. It is highly recommended to change your sprockets before significant wear occurs to the teeth. If your sprocket has worn down teeth, your chain may not align properly and as a result could snap under tension, or if you’re lucky just pop off. Although it may not sound like much, but when your chain snaps or breaks due to tension, your engine casing may be the next to go.


As your chain snaps, it whips around the counter sprocket and slams into your engine casing; in most cases where this happens, your engine casing may crack or be damaged causing you more problems than you can imagine. This problem can be mitigated with the case savers that are made by various companies like Hammerhead, Acerbis, T.M Deisgnworks and others! The case savers are intended to protect the engine casing from the chain if it ever snaps or breaks and will save you a headache ( or multiple headaches) in the future. The Hammerhead case saver is made from Billet Aluminum which will definitely protect you engine case from the brut forces of a snapped chain.
