Sprocket size and final drive

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. For more bottom end and faster acceleration, use a small countershaft/front sprocket or large rear sprocket.

What does putting a bigger rear sprocket do?

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.

Does a bigger sprocket give you more torque?

Sprocket sizes are a part of the gearing ratios for the bike, as are the wheels and transmission. If the front sprocket is small and the rear is large, you will have more low end power but less top speed. The smaller the front and the larger the rear, the more torque you will have, with a drop in top speed.

What does more teeth on a 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 sprocket is best for speed?

Sprockets : Easy way to gain Speed & Acceleration
A bigger rear sprocket/ smaller front sprocket will give you an increase in acceleration but decrease your top speed.A smaller rear sprocket/bigger front sprocket will reduce you acceleration but increase the top speed.

How do I get low end torque on my motorcycle?

A smaller sprocket on the front, bigger on the rear will take-away top end speed and increase bottom-end torque. A bigger sprocket on the front, and smaller on the rear will increase top end speed and take away bottom-end torque.

How do you pick a sprocket size?

Sprocket Ratios

This is determined by the the number of teeth on the front sprocket, compared to the number of teeth in the rear sprocket. For example, a motorcycle with a 17-tooth front sprocket and a 45-tooth rear sprocket would have a ratio of 2.65 (45 divided by 17 = 2.65).

How can I increase my gearbox speed?

Spur and helical gear reducers are the best candidates for use as a speed increaser. Generally a helical or spur gear speed reducer may be used as a speed increaser within the same speed.

What does different size sprockets do?

The purpose of changing sprocket sizes is to alter the relationship between engine speed on your tachometer and road speed on your speedometer.
