FORK SEALS

Being off-road machines, dirt bikes are susceptible to wear and tear on particular parts after constantly being put through some of the dustiest and dirtiest conditions, and your fork seals are one of the regular components to let go. Indicators your fork seals need to be replaced:

  1. Seals leaking oil from the fork inner chamber (usually ending up all over your brakes making it difficult to slow down)
  2. Stiff or sticky feeling fork action
  3. Reduced fork performance/ increased bottoming from fork oil loss

What causes leaking fork seals?

The most common cause for any of these symptoms is from dry oil seals or dirty fork bushes, and the main culprit for this is dirt and cleaning chemicals being trapped in the outer dust seal, then over time working its way through the fork seal and into your fork bushing. Another contributing factor to leaky fork seals which many riders overlook is the oil itself, which is common knowledge that all oil has a lifespan and needs to be replaced.
