What does a smaller front sprocket do?

What does a smaller front 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 does a sprocket with more teeth 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. For more bottom end and faster acceleration, use a small countershaft/front sprocket or large rear sprocket.

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.

What does changing the front sprocket on a dirt bike do?

The purpose of changing sprocket sizes is to alter the relationship between engine speed on your tachometer and road speed on your speedometer. Let’s say your motorcycle comes with an 18-tooth sprocket in the front and a 43-tooth sprocket on the rear wheel. Once you have a new ratio in mind, take a look at your bike.

How do I know what size sprocket I need?

To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.

How do I choose a motorcycle sprocket?

Guide to Choosing Motorcycle Sprockets

  1. Choose Your Sprocket Material. Virtually all motorcycle sprockets are manufactured from steel or aluminum.
  2. Replace Both Sprockets.
  3. Replace the Chain with the Sprockets.
  4. Pitch and Width.
  5. Sprocket Ratios.
  6. The Effects of Changing Sprocket Ratios.

Is it better to have more teeth on a sprocket?

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. For taller gearing, a one-tooth-larger countershaft sprocket is often the best bet.

Is more teeth on a sprocket better?

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.

How big is a 60 tooth sprocket?

Inside Diameter: 1.1245 in. Thickness: 0.086-0.092 in.

What sprocket size is best for BMX?

Many different sizes of Sprocket exist so its important you know which one to get. Predominantly most popular is 25 Tooth, to maintain a traditional gearing this would mean running a 9 tooth rear cassette or driver.
