Gearing down by installing a larger rear sprocket (like with our YZ example) increases the final drive ratio and reduces top speed, but can increase acceleration. Gearing up, like with a smaller rear sprocket, decreases the final drive ratio and adds more top speed to your motorcycle or ATV.
What will a bigger sprocket do?
Gearing a bike up to produce higher top speed with less acceleration is done using a larger countershaft (gearbox) sprocket or a smaller rear sprocket. Gearing a bike down giving it more acceleration with lower top speed is done using a smaller countershaft (gearbox) sprocket or a larger rear sprocket.
How does changing sprocket size affect speed?
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 changing sprockets on a motorcycle do?
By increasing the difference in tooth count between the front and rear sprocket (and lowering the gearing) you are increasing the amount of torque that is applied through the rear wheel. The increase in torque means the wheel spins up easier and you accelerate faster.
What does more teeth on a rear sprocket do?
The two sprockets are measured by their number of teeth. 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 sprocket is best for speed?
For more bottom end and faster acceleration, use a small countershaft/front sprocket or large rear 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).
How can a sprocket increase top speed?
To increase low end power, you should increase size of rear sprocket or decrease size of front sprocket. To increase top speed, you should reduce size of rear sprocket or increase size of front sprocket.
How do I increase the top speed of my motorcycle?
5) Gearing – A motorcycle can be made quicker or much faster by making changes in the gearing of the same. The right combination of front and rear sprocket can help you get the best combination of acceleration and top speed. Changing the number of teeth makes all the difference.

How do I know what size sprocket I need?
To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
How long does a motorcycle chain and sprocket last?
A common rule is to replace both front and rear sprockets every time you replace your chain. This is a good rule to follow if your chain has lasted for it’s full life of, say, 15,000 miles. But, sometimes a sprocket replacement can wait in cases where you’re replacing a prematurely worn chain.
How do you know if your motorcycle sprocket is worn?
Look closely at the sprocket teeth to see if they have become sharp at the tips and/or slightly curled. The teeth on a new sprocket are straight and have a flat or domed shape at the tip. If the teeth are sharp, the sprocket is worn.

Will a 428 chain fit a 420 sprocket?
You can probably use the 428 chain on the 420 sprockets. Not the other way around though. 428 sprockets are too thick for a 420 chain. Depending on the sprocket cut.
Why do BMX have small sprockets?
Many BMX bikes use a U-style rear brake mounted to the top of the frame chain stay. With this style of brake mount, a very small sprocket and rear cog will lower the chain so much it contacts the top of the brake and inhibits pedaling.
Does changing sprockets affect speedometer?
changing your gearing and then installing a speedohealer will calibrate your speedometer, but your odometer will now be off.
