Knowing the fork diameter of a dirt bike can be important for various reasons. It allows riders to find compatible aftermarket parts, such as fork seals or fork springs, that are specifically designed for their bike. It also helps riders determine if their fork is damaged or needs servicing, as any significant deviation from the standard diameter could indicate a problem with the suspension.
To measure the fork diameter, a caliper or measuring tape can be used to measure the outer diameter of the fork tube. It is important to measure at the lower part of the fork tube, as the upper part may have additional components that can affect the measurement. Once the outer diameter is determined, it can be compared to the known standard measurements to determine the fork diameter.
Overall, understanding the dirt bike fork diameter is essential for riders who want to maintain and customize their bike’s suspension. By knowing the diameter, riders can ensure they are using compatible parts and make informed decisions about the maintenance and performance of their dirt bike.

Methods
To measure the diameter of a dirt bike fork, you can use one of the following methods:
1. Calipers
One of the most accurate ways to measure the fork diameter is by using calipers. Calipers are a measuring tool with two arms or jaws that can be adjusted to measure the distance between two opposite sides of an object. To measure the fork diameter, you can simply place the calipers on the outer side of the fork, ensuring that the jaws are in contact with the fork tube. Make sure the calipers are perpendicular to the fork tube for an accurate measurement. The reading on the calipers will be the fork diameter.
2. Tape Measure
If you don’t have calipers, you can use a tape measure to measure the fork diameter. Wrap the tape measure around the fork tube and note the measurement where the tape overlaps. Make sure the tape measure is pulled tight and aligned parallel to the fork tube to get an accurate measurement. The measurement you get will be the fork diameter.
It’s important to note that the fork diameter may vary slightly depending on the make and model of the dirt bike. Therefore, it’s recommended to consult the manufacturer’s specifications or the bike’s owner’s manual for the accurate fork diameter measurement.
Method 1: Using a caliper
If you want to measure the diameter of your dirt bike fork, one of the most accurate methods is by using a caliper. A caliper is a measuring tool that can be used to measure the distance between two opposite sides of an object.
Here is a step-by-step guide on how to measure your dirt bike fork diameter using a caliper:
- Start by setting the caliper to measure the outside diameter. Make sure the caliper jaws are closed and locked in place.
- Align the jaws of the caliper with the outer edges of the fork tube. Ensure that the jaws are making contact with the tube and are parallel to each other.
- Slowly open the caliper jaws until they make contact with the opposite side of the fork tube. Take note of the measurement displayed on the caliper.
- Record the measurement in millimeters or inches, depending on the unit you prefer.
It is essential to take multiple measurements at different points along the fork tube to ensure accuracy. This is because the fork tube diameter may not be uniform throughout its length. Take the average of these measurements for the most accurate result.
Using a caliper is a precise and reliable method of measuring your dirt bike fork diameter. It gives you an accurate measurement that can be used when purchasing replacement parts or making adjustments to your bike’s suspension.
Method 2: Using a measuring tape
If you don’t have a caliper or a digital measuring tool, you can also measure the diameter of your dirt bike fork using a measuring tape. While this method may not be as accurate as using a caliper, it can still give you a fairly good estimate of the fork diameter.
