What Causes Dirt Bike Fork Seals to Leak?
The main reason a fork seal leaks is due to debris getting under the seal. Although there is a dust seal in place to prevent this from happening, it might not always do the trick.
There are, however, a few other reasons as to why your fork seal might be leaking.
Torn dust seal
Nick in the fork tube
General wear and tear
It’s important to check your seal and inspect for further wear and tear issues before getting back on the bike.
Hopefully, the cause is just from debris getting into where it wasn’t invited, and you’ll only be off the track for a few minutes while you fix the issue. That is if you have theSeal Doctor of course.
How do you Clean Under Fork Seals?

How Does a Leaking Fork Seal Affect Your Bike?
If you have a leaking fork seal, you should not ride your bike. We can’t stress the danger of this enough. The oil from your forks can leak out onto your front brake, this causes your front brake to lose it's stopping power. Furthermore leaking fork seals means your forks no longer have the appropriate oil level inside the fork which can cause your fork components to not have appropriate lubrication and cause internal damage.
It’s important to know how a leaking fork seal will affect your bike and your ability to get back on the track.
Leaking fork seals, if gone unchecked and unfixed can cause the following issues:
Affects suspension tuning
Soaks front brake pads
Poor shock absorption
All these issues make for unsafe riding conditions, and you should not ride your dirt bike if you suspect or find that your fork seal is leaking. It’s extremely dangerous and should be fixed immediately or at least before you get back on the track.
How Do You Check if Your Dirt Bikes Fork Seals are Leaking?
There will be a few tell-tale signs that will determine if your fork seals are leaking. The first and most obvious, is oil dripping down the fork leg of the dirt bike. If you see oil dripping down, inspect for the cause straight away and remember to clean the oil off before you do anything else.
Here are a few other signs to look out for:
If your suspension feels bouncy and uncontrollable, this is another sign that your fork seal might be leaking.
You can check this (if you haven’t already felt it on the track) by getting on your bike while it’s stationary, hold the brakes in, and give it a few bounces. The suspension might be loose, and the forks could be “springy”. This is a sign you have bad or leaking fork seals.
Run a cloth up the fork leg to check for oil
Sometimes we can’t see oil on the front suspension or fork leg if it’s dirty. Use an old cloth or your fingers, wipe the lower part of the forks to check for oil.
I’d recommend doing this regularly as a routine maintenance check. It’s hard to tell if there are any oil leakages when there’s already so much debris and dirt built up on the bike from regular use.
Oil under your bike
Noticed a puddle of oil under your bike recently but not sure what’s caused it? Try the Seal Doctor to check and clear out any debris from under the fork seal. Hopefully, that’s what’s caused the oil leak but typically if there’s a large pile under your bike, you might there’s another issue completely, like a nick in the fork tube.
When Should You Replace Your Fork Seals?
If Seal Doctor doesn’t do the trick, it might be time to replace your fork seals. Yes, this means you can’t get back on the track straight away, but it’s for your safety and the safety of others.
Fork Seals typically last around 2 years, depending on how often they’re being ridden. The more you ride, the more wear and tear damages your bike will sustain.
Complete routine maintenance and check-ups often to avoid costly fixes and unfortunately timed mechanical problems.
If your fork seals have had a fair amount of leakage, you might want to check your oil levels and get them topped up once the fork seal has been fixed or cleaned.
In the case of fork seals leaking, the main issue is generally caused by debris getting under the dust seal. This is an easy fix with Risk Racing’s Seal Doctor tool if you have it on hand. While using the Seal Doctor, you might find more oil slowly leaks out of the fork seal. Once the dirt has been removed it should clear up the issue immediately. We still recommend checking for other causes to establish if there are any other concerns. Check out Risk Racings fork seal leak cure here, the Seal Doctor.
