Fork seals are one of the most important components on your dirt bike. They keep the oil in your forks from leaking out and keep the air pressure in your forks consistent. If your fork seals start to leak, it can cause a number of problems.

You’ll first notice that your forks will start to feel softer. This is because the oil is leaking out, and there’s less oil to lubricate the internals of your forks.

You may also notice that your bike will start to feel unstable, as the air pressure in your forks will be inconsistent. This can make riding extremely dangerous.

When you notice the fort seals leaking, follow a few steps. First, take a look at your fork tubes. If they’re covered in oil, it indicates that your seals are leaking. Another way to check is by doing the “fork bounce test.”

With this test, you push down on one side of your forks while holding the other up. If there’s significant movement in the fork tube, it’s likely that your seals are worn out and need to be replaced.

If you find that your fork seals are leaking, don’t panic! It’s relatively easy to replace them yourself. With a few simple dirt bike fork seal cleaner tools and patience, your bike can be back up and running quickly.

Why Do Dirt Bike Forks Leak?

Dirt bike forks are designed to be durable and withstand much abuse. Over time, the seals that keep the fork oil inside the forks can start to leak. There exist multiple justifications for it, which include the subsequent:

  • The seals are old and worn out
  • The seals are damaged
  • There is too much pressure on the seals
  • The forks are not level

If your dirt bike forks are leaking, it is important to repair them immediately. Otherwise, you may damage your forks or have to replace them entirely. Our guide will help you how to repair fork seals leaking on your dirt bike.

  1. When you start repairing fork seals, you must remove your bike’s fender and front wheel.
  2. Use a seal driver or similar tool to remove the old fork seals from the forks. Be careful not to damage the fork tubes when doing this.
  3. Clean the inside of the fork tubes with brake cleaner or another similar solvent. This will remove any buildup of oil or grime that could prevent the new seals from sealing properly.
  4. Install the new fork seals into the forks. Ensure they are seated properly and there is no gap between the seal and the fork tube. Use a seal driver or other tool to seat them if necessary.  
  5. Reinstall the front wheel.

What Tools Do You Need to Repair Fork Seals?

For repairing fork seals, you need to have the following tools. Here is a list of what you will need to dirt bike fork seal cleaner:

  • Tape measure
  • Socket set and wrench set
  • Hammer
  • Punch
  • Screwdriver set
  • Soft brush (to clean seal area)
  • Rags or paper towels (to clean up any spills)
  • Fork oil
  • New fork seals
  • Zip ties (to keep your work area clean)

How To Disassemble The Forks

Assuming your goal is to clean and inspect the fork internals, you must remove the spring(s) first. Some forks have a single coil spring, while others have two. You can find the circlip or retaining clip to the fork top.

It will keep the spring in its place. Once the clip is removed, the spring(s) can be compressed and removed from inside the fork tube.

You will then need to remove the damper rod inside the fork leg. The damper rod controls the rebound of your forks (how quickly they return to their original position after being compressed). When you remove the bike rod, it’s time to loosen the damper rod.

You should now see the fork oil inside the leg with the springs and damper rod removed. At this point, you can either clean out the old oil and start fresh or inspect it for any debris or metal shavings (indicators that something is wrong inside your forks).

If everything looks good, you can now reassemble your forks by following these steps in reverse order. Be sure to use new fork oil and check your owner’s manual for recommendations on how much oil to use (typically around 10-20cc per fork leg).

How To Replace The Fork Seals

Assuming you have the necessary dirt bike fork seal cleaner tools, the first step is to remove the front wheel and then the forks. Once the forks are removed, separate the fork tubes from the triple upper clamp.

Next, using a seal driver or similar tool, drive out the old fork seals from each tube. Now it’s time to clean out any dirt or debris in the tubes before installing the new seals. To do this, you can use a small brush or compressed air.

Once the tubes are clean, lightly lubricate the new fork seals with fork oil and install them into each tube. Using your seal driver or similar tool, tap them in until they’re flush with the tube. Now reassemble your forks and install them back onto your bike.

Fork Bleeding Procedure

If your dirt bike’s fork seals are leaking, don’t despair! You will find it tough, but with some practice and usage of the tools, you can repair it easily.

Get the following supplies in place to start the fork seals process:

  • New fork seals (Make sure to get the correct size for your make and model of a dirt bike.)
  • A clean workspace
  • Screwdrivers
  • Hammer
  • Pliers
  • A set of Allen wrenches or a socket wrench set
  • A bicycle pump or an air compressor (optional)

 Once you have dirt bike fork seal cleaner, follow these steps:

  1. Remove the front wheel and park your dirt bike on a level surface.
  2. Unscrew the cap at the top of each fork tube and slowly release any pressure.
  3. Care to pry out the old fork seals using screwdrivers, hammers, and pliers.
  4. Inspect the area around the seal for any damage or debris and clean as necessary.
  5. Before starting, you can apply grease and insert it into the place using a tool or your fingers. Be careful not to damage the seal while doing this.
  6. Using the Allen wrenches or socket wrench set, tighten the top caps until they’re snug but not too tight – you don’t want to strip the threads!
  7. Put the front wheel back.

Reassembling Your Suspension System

The suspension system of a dirt bike comprises different parts. These parts should work fine to enjoy the bike ride. If your fork seals are leaking, it’s important to take the time to repair them. Our guide will provide you with an uncomplicated method to execute it proficiently.

The first step involves removing both the axle and the front wheel. Next, remove the brake caliper and disc. Once these components are out, you can remove the fork tubes from the triple clamps. Be careful not to damage the lower legs as you do this.

With the fork tubes removed, it’s time to disassemble the forks themselves. Start by removing the springs and dampers. Then, unscrew the top caps and remove the rebound adjusters. With all of these parts removed, you should now have access to the fork seals.

Remove the old seal by prying it out with a flathead screwdriver or a seal removal tool. Make sure not to damage the inner wall of the fork tube as you do this. Once the old seal is out, clean out any debris inside the tube.

Now it’s time to install the new seal. Start by lightly greasing both sides of the seal with fork oil. This will help it slide into place more easily. Carefully press the new seal into place using a seal installation tool or a piece of scrap metal tubing.


Following this guide’s steps, you should have successfully repaired your dirt bike fork seal cleaner. Congratulations! Now you can get back to riding without worry.

Although repairing it may pose a challenge initially, with consistent practice, you will become proficient.
