Question: What does changing sprockets on a motorcycle do?

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).

Does changing sprockets affect engine?

As you may already know, when you change the gearing like this the trade off comes in the way of top end speed. By lowering the gearing you cause the rear sprocket and wheel to turn more slowly in relation to engine speed.

What does increasing rear sprocket do?

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.

Does changing sprocket affect speedometer?

Most new bikes have the speedo driven off the output shaft of the tranny. Changing the sprocket gearing will definitely effect both the speed indicated and miles ridden.

Is more teeth on a sprocket better?

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 wheelies?

If your wanting to do long street wheelies, then a smaller 14t front sprocket and a little clutch dump will do the trick. IMHO , stunting slower stuff with bigger sprockets are A LOT safer than faster wheelies.

What is the best gear ratio for a go kart?

To determine the gear ratio necessary for your go kart or mini bike you must know the limit of your top speed. When using a clutch to drive your go kart the top speed on flat terrain is 35mph, if the terrain is hilly or the weight of the driver is high the top speed should be 25mph.

What is final drive ratio of motorcycle?

To determine the final drive ratio, divide the rear sprocket size, say 49 teeth, by the front or countershaft sprocket size, say 13 teeth (like a new Yamaha YZ250F). In this case, the Final Drive Ratio is 3.77 – the front sprocket revolves 3.77 times to make one complete revolution of the rear sprocket.

What’s the best sprocket size?

For taller gearing, a one-tooth-larger countershaft sprocket is often the best bet. For more subtle changes, combine that plus-one-tooth front sprocket change with a minus-one-tooth change at the rear sprocket.

Does a bigger rear sprocket give more torque?

A larger rear sprocket will reduce top speed but increase rear wheel torque at the same road speed as RPM will increase.

How can I make my bike sprocket faster?

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 long will a motorcycle chain last?

But chains wear out over time and need replacing. So, how often should a motorcycle chain be replaced? In general, a properly maintained motorcycle can last 20,000 to 30,000 miles, sometimes more. But, some last as little as 5,000 to 10,000 miles.

How do you increase top end speed on a motorcycle?

A lighter exhaust system and use of alloy wheels in place of spoke wheels can drastically improve the performance of your bike. Getting rid of the centre stand, saree guard, metal grab rails, leg guard, and a few other components can also save more than 5-6 kgs in the first attempt.
