How can I know my fork springs wear out?

You can tell if you front springs are worn out by how much resistance they give you when you hit the front brake or when you hit a bump. If you notice your front end is diving in the corners and you feel the bike bottom out when you hit a bump, it is possible that your front fork springs are worn out. Another sign is if you notice your motorcycle is not sitting evenly, or your motorcycle tires are not wearing evenly. These are also signs your fork springs may be worn out.

How do I know if your steering / neck bearings are loose?

The best way to check your front steering bearings is to get the front of the motorcycle off the ground. You don’t want any weight on the front of the motorcycle. Next move your motorcycle handlebars from side to side. Everything should feel smooth and consistent. If you feel any hesitation or vibration coming through the bars, your bearings might be damaged. Also pay attention for any spots where the front end hesitates when you turn the bars side, to side; this could be a notch in the bearing race from wear. In this case you should replace your neck bearings and races. Another way you should check to see if the bearings are loose is by grabbing the forks and trying to move them side, forward and back. If you feel them wiggle and there is play at the steering head, tighten your bearings to spec and then test them again to see if they operate smoothly. If they don’t, it is probably time to change your bearings. You can also gauge the tightness of the bearings by, with the front of the motorcycle off the ground, aligning the wheel straight forward and seeing how easily it 'flops' to the side. It shouldn't slam to the side, it should be a nice even movement.

When should fork seals be replaced?

Fork seals should be replaced if you notice that they are cracked, or if you notice that they are leaking. When fork seals are leaking it could be some fluid on the fork tubes, or if they are really bad it could be actively running down the lower legs. You need fluid in your front forks for them to operate properly. The fluid is there to allow some control of the compression and rebound of the forks. It is also there to keep everything cool while the forks are in motion. If you loose too much fluid, you can seriously damage your forks, or cause handling and stability issues.

Can I ride with a leaking fork seal?

Yes, you can ride for a period of time with a leaking fork seal, but you should fix it as soon as possible. You need the fork oil to keep your forks from sustaining damage during use, and to ensure the motorcycle handles as it should. If one fork leg is losing fluid, and the other isn't, it can cause an imbalance that can lead to stability issues. Safety first!

Choosing motorcycle fork components is important

When you are building a custom bike, it is a good idea to spend some time on your front forks. Changing the oil and adding some new seals is a good use of your time. Nothing is worse than putting a bike together and then having to take the front end back off due to a bad fork seal. Rubber seals dry out after time and have to be replaced or you will have a leak and a mess on your garage floor.

Lowbrow Customs carries a variety of items for the front forks. They have common replacement items for parts that tend to wear out like motorcycle fork seals, motorcycle fork springs, and neck bearings. They also carry custom motorcycle fork components like motorcycle fork tubes, low profile fork caps, fork boots, and motorcycle stem nuts and hardware. All of these items are products we use on our personal bikes. They have been tested, proven, and now we can offer them to you.

Why buy fork components at Lowbrow Customs

If you are building a custom motorcycle Lowbrow Customs has some motorcycle fork components for sale online that will allow you to refresh or rebuild your forks to look and function as they should. We carry an assortment of motorcycle fork components for both Harley Davidson® and Triumph® motorcycles. We carry direct replacement parts like our fork seal kits, and we carry custom fork components like our motorcycle fork clamps.

For example, if you are building a dirt tracker take a look at our rubber fork boots. They protect your forks while providing that vintage dirt tracker look. Combine these boots with our low-profile fork caps that allow you to run lowered handlebar setups. This will allow you to achieve that classic dirt tracker look that is so popular.
