Fortunately, your Front Suspension Forks are relatively self-sustaining and as long as you’re keeping them clean and taking them in for yearly service, you shouldn’t have any problems. But you still need to know what keeps them working well, so keep reading to learn how to maintain them.


Just about every Maintenance tip for your Bike starts with a good cleaning, and Front Fork Maintenance is no different.

Keeping your forks clean is one of the best ways to extend the life of your forks and will also keep them running better overall.

Dirt and grime can be really tough on your Bike parts, causing them to lose performance over time, even failing completely.

This is why manufacturers stress the importance of lubrication and cleaning.

The goal, is to keep the dirt out and the oil in.

If you can balance this, you’ll get the most out of your Bike and its components.

You can clean your front forks with water but avoid spraying directly on the seals, so you don’t get any water inside the fork. If you do decide to use a high-powered spray, make sure you turn the bike upside down. Remove all the dirt and grime from the Fork Stanchions and from around the Fork Seals.

Once you’ve made sure everything is clean, its time to move on to the next step.

Inspect the Fork Stanchions

Now that your Forks are clean, its time to check one of the most vital parts – The Fork Stanchions.

It can be hard to spot any issues with your Fork Stanchions, when they’re clean, it’s a lot easier to spot any damage.

You’re looking for scratches, dents, wear or play in the bushings.

All of these are signs of something serious going on with your Forks and spotting them early can help you avoid costly repair.

After you visually inspect the forks for scratches or damage, hold your front brake and rock your Bike backward and forward. If you notice any “play” in the bushings around the stanchions, it’s time to take your Bike in for a service.

It’s important to note that the beginner rider shouldn’t service their Forks if they’re not confident. Front Fork servicing is usually completed by a Bike Mechanic or similar.


Now that you have your Forks cleaned, you may think it’s time for lubrication.

But don’t get too ahead of yourself, you most likely don’t need to lubricate your Forks.

In fact, the lubrication within the Lower Forks should be enough to keep everything lubricated. So there is no need to lubricate the Stanchions or the Seals.

The Lower Forks contain a lot of components that work to keep the Forks well-oiled and dirt repellent.

This comes down to a series of Bushings and Foam rings that seal the system from dirt, while keeping the oil in.

Make sure you take your Forks in yearly for Maintenance and maintain at least 5 to 10 ml of oil in the Lower Fork.

Combine this with regular cleaning, and you shouldn’t run into any trouble.

Service the Lower Forks

Eventually, you will have to service your Lower Forks.

Over time, you lose oil, bushings wear, and performance is impacted.

Taking your Bike in for a Lower Fork Service or service them yourself is an essential step in Bike Maintenance.

As mentioned before, this type of service is best left to the professionals, however, if you feel you’re up to the task, you can try it yourself.
