What the AI looks for in Powersports Seals
- Size
- Match inner diameter × outer diameter × width, or the OEM part number Even a slightly undersized or oversized seal will leak.
- Lip design
- Use double-lip or dust-lipped seals where mud and water are present The extra lip keeps grit away from the sealing lip.
- Material for the job
- Use fluorocarbon (Viton) seals for hot or fuel-exposed locations; standard nitrile is fine elsewhere if it matches OEM The wrong material hardens or swells and then leaks.
- Fork seal kits
- Buy fork seals by fork tube diameter and model, and replace the dust wipers along with them Worn wipers let dirt in and quickly ruin new oil seals.
Brands that matter
- All Balls Racing: Fork seal, wheel seal and engine seal kits by model.
- SKF: Fork seal kits often regarded as an upgrade over stock.
- Pivot Works: Seals included in vehicle-specific bearing kits.
- Athena: Engine gasket and seal kits for many motorcycles.
- Moose Racing: Broad catalog of replacement seals for ATVs and dirt bikes.
What to avoid
- Reusing a seal that has already been removed
- Prying or installing with a screwdriver instead of a seal driver
- Installing a seal dry (lubricate the lip first)
Questions
My fork seal leaks. Do I need a new seal?
Sometimes dirt under the lip is the cause, and cleaning it can fix the leak. If the leak returns, replace both the seal and the wiper, and check the fork tube for pitting.
