The chain grips the wheel sprocket and turns the motorcycle's engine power into forward momentum by turning the wheel.

What does the drive sprocket do?
Chain tracked vehicles
In the case of vehicles with caterpillar tracks the engine-driven toothed-wheel transmitting motion to the tracks is known as the drive sprocket and may be positioned at the front or back of the vehicle, or in some cases both. There may also be a third sprocket, elevated, driving the track.
Do sprockets make your bike faster?
The solution to more power or more top speed is chain/sprocket kit. ... 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 sprockets work on a bike?
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.
What does 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.
Is more teeth on a sprocket better?
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 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).
What does adding a tooth to the 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.
How 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%.
How many teeth does a bike sprocket have?
On a typical road bike, the smallest sprocket will typically have 11(11t) or 12 (12t) teeth and the largest 25 (25t) to 32 (32t) teeth.
How does sprocket size affect torque?
Changing your rear sprocket won't give you more mid range or change the engine power curve in any way. It will alter the torque at the rear wheel at all RPMs. The bike should accelerate faster through the gears but you will also loose out on top speed. You don't need to get dyno tuned just for changing a sprocket.
Do gears increase torque?
When a rotary machine such as an engine or electric motor needs the output speed reduced and/or torque increased, gears are commonly used to accomplish the desired result. ... The rotary machine's output torque is increased by multiplying the torque by the gear ratio, less some efficiency losses.
Does more teeth mean more torque?
Thus, the larger the tooth ratio, the greater the torque multiplication, but, of course, the greater the number of turns the driving gear must exert for one turn of the driven gear.
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.
