Motorcycle regearing is a great way for riders to customize the performance of their ride. It’s relatively easy and it produces noticeable results that you can feel immediately! There are plenty of reasons that you might want to change the gearing of your bike. Maybe you want better acceleration while navigating the busy city streets. Maybe it’s better acceleration for a day at the track that you’re after. Or maybe you just want lower RPMs while riding at highway speeds. Whatever your reason might be, you are in the right place. We’d be happy to walk you through what regearing your bike actually does, and how to do it.
We’ll start with the basics. Regearing your motorcycle is the process of changing the size and number of teeth on either your front or rear sprocket or both. When you change the number of teeth on one of your sprockets, it’ll change the relationship between them. More specifically, it changes the number of times that your front sprocket needs to spin to make your back tire rotate one complete rotation.
If you add a tooth to the front sprocket, or take one from the rear, you’ll be you’ll be raising the gear ratio of your bike. This will result in greater top end speeds, and lower RPMs at highway speeds, but it will also result in slower acceleration.
If you remove a tooth from the front sprocket, or add teeth to the rear sprocket, you’ll be lowering the gear ratio. This means that your bike will have better acceleration, but will have a lower top speed than before. Riding at highway speeds can also be less smooth, as your bike’s RPMs are higher than they would have been at that speed with your previous gear setup.
As you can see, there is always a trade off when changing your gearing. There is no right or wrong way to gear your bike, and it’s your job to find what will serve you best.
When changing the gear setup, changing just one tooth on the front sprocket is the equivalent of changing about three on the back. Keep this in mind while deciding just how much of a change you want to make.
Sprockets and chains are best changed as a set. When you pair a new sprocket with an old chain, it can cause uneven wearing, which will result in shorter sprocket life. By changing everything at once, you are giving them a better chance to become acquainted and wear evenly.
Now that you have a basic understanding of why you’d want to change your gear ratio and what it can do for you, we should probably tell you how to do it. We’ve made some simple instructions for you to follow. Certain motorcycles might have slightly different processes, but this is a general format that will be applicable to the majority of bikes.
Well, you’ve done it. You now know why you might want to regear your motorcycle, what it actually does, and how to do it. (Assuming you didn’t skim to the final paragraph.) You’re one step closer to being a certified garage mechanic! If you have any questions or comments, let us know down below.
