You may find this counter-intuitive, but to go faster, the final drive sprocket needs to be smaller, not bigger. Conversely, to go faster, the clutch sprocket needs to be bigger. So, a simple way to change your gearing is to have one or more extra primary drive sprockets and/or final drive sprockets.
What will a smaller front sprocket do?
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 is faster small or big 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. … For more bottom end and faster acceleration, use a small countershaft/front sprocket or large rear sprocket.
What does changing your sprocket size do?
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 a sprocket increase top speed?
To increase top speed, you should reduce size of rear sprocket or increase size of front sprocket. Ideally, one should change rear sprocket because it is bigger in size and allows for a much finer level of adjustment.
What sprocket is best for torque?
Use rear sprockets to get close, front sprockets to fine tune. Larger rear sprocket, smaller front. Ratio 3 teeth on the rear equals 1 tooth on the front. Up 3 on the rear for torque or down 1 on the front.
Should I change the front or rear sprocket?
Doing the rear is better from a chain and sprocket wear perspective. A smaller front sprocket will excert more force on the chain and wear it and the sprocket faster which is why most will tell you to do the rear. If changing front, I would recommend against more than -1.
Which bike gear is fastest?
High Gear = Hard = Good for Descending: The “highest” gear on your bike is the largest chain ring in the front and the smallest cog on your cassette (rear gears). In this position, the pedaling will be the hardest and you’ll be able to accelerate while traveling downhill.
How can I increase my cycling speed?
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 can I make my bike push faster?

Does changing sprockets affect speedometer?
The speedo drive is taken from the gearbox, so the speedo would be out by the percentage change in the gearing. A front sprocket one tooth bigger and rear sprocket two teeth smaller would give 15.75mph per 1000 rpm, an increase of nearly 13%.
What is the best gear ratio for speed?
In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.
Can you make a 125cc faster?
Upgrade your front, rear or both sprockets for increased power-band control. Motorcycles with 125cc engines lack top speed compared to larger displacement engines. Purchasing a front sprocket with less teeth than stock and a rear with more teeth than stock can help. … Sprocket changes affect the power band of each gear.
How can I speed up my chain drive?
To speed up a drive, you can either make the Driver larger or the Driven smaller. Either is acceptable. Since changes to your pulley sizes proportionately effect the speed, you can easily determine the needed sizes of the new pulleys.
