What happens if I put a smaller front sprocket on my motorbike?

Substituting a larger front or smaller rear sprocket lowers the ratio (sometimes called “taller” gearing), resulting in more speed for a given engine rpm. Likewise, a smaller front or larger rear sprocket gives less speed for a given rpm (“shorter” gearing).

What does less teeth on front sprocket do?

Adding teeth to the front and rear sprockets have opposite effects. Installing a larger countershaft sprocket creates higher gearing, while a larger rear sprocket lowers gearing. Similarly, a smaller front sprocket lowers the gearing while a smaller rear sprocket makes the gearing higher.

What happens when you change front sprocket?

Adding teeth to the front and rear sprockets have opposite effects. Installing a larger countershaft sprocket creates higher gearing, while a larger rear sprocket lowers gearing. Similarly, a smaller front sprocket lowers the gearing while a smaller rear sprocket makes gearing higher.

Which sprocket is faster?

You can gear up by using a smaller rear sprocket or a larger countershaft/front sprocket. Gearing up adds more speed and decreases the final drive ratio. You can gear down by using a larger rear sprocket or a smaller front sprocket. Gearing down reduces speed and increases the final drive ratio.

What does changing front sprocket do?

What is a front sprocket?

A front sprocket, or drive sprocket, rotates with your bike’s transmission output shaft. This rotation, with connection to a drive chain, creates the rotation of the rear sprocket, which ultimately rotates the rear wheel, causing your bike to move forward.

Does less teeth on rear sprocket?

As a quick rule of thumb, the more teeth on the rear sprocket, the lower the gearing. Conversely, the fewer teeth on the countershaft sprocket, the lower the gearing.

What does changing the front sprocket do?

For every 1 tooth that you change on the front sprocket is like changing 3 to 4 teeth on the rear (and that’s true for higher gearing ratios, too). This configuration creates that smaller gearing ratio that works best for tracks with lots of turns, few long straightaways, like Arenacross, and tight trail riding.

How many teeth should you change on a front sprocket?

For every 1 tooth that you change on the front sprocket is like changing 3 to 4 teeth on the rear (and that’s true for higher gearing ratios, too). This configuration creates that smaller gearing ratio that works best for tracks with lots of turns, few long straightaways, like Arenacross, and tight trail riding.

Is it worth it to change just one sprocket?

If your chain is relatively new, it will not hurt it to change only one sprocket. Considering that a front sprocket is typically only $20-30, I recommend changing it as an inexpensive way to test a new gearing ratio, before you take the plunge and spend the money to change both sprockets and your chain.

How does sprocket size affect motorcycle performance?

It’s All About The Gearing Ratio Your gearing ratio is, simply put, the ratio of teeth between the front and rear sprockets. This ratio determines how engine RPM is translated into wheel speed by the bike. Changing sprocket sizes, front or rear, will change this ratio, and therefore change the way your bike puts power to the ground.

How can I increase the speed of my front sprocket?

you could increase the rear sprocket by two teeth or drop the front sprocket by one tooth to get more acceleration. Going with a larger rear sprocket could require a new (longer) chain. Replacing the front sprocket is typically the easiest and least expensive route.
