What does putting a larger rear sprocket do?

What does putting a larger 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 changing sprocket 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%.

Is it better to change 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.

What does a smaller rear sprocket do on a motorcycle?

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.

Does a bigger rear sprocket give 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.

Does bigger rear sprocket increase 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.

What will a smaller rear sprocket do?

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 sprocket is best for speed?

For more top end and faster top speed, use a large countershaft/front sprocket or smaller rear sprocket. This creates a taller gearing ratio that’s best for high speed situations without many tight turns like wide open desert racing.

How do you count the number of teeth in a sprocket?

The easiest way to calculate sprocket ratio is to count the number of teeth on both the driving and the driven sprockets and divide the first by the second. This ratio tells you how many times the driven sprocket turns for every revolution of the driving sprocket.

Are rear sprockets smaller?

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.
