Fork Oil Seals, most VMX models



We also have Fork Oil Seal and Dust Seal Combo Kits and Fork Seal Savers, which can extend the life of your seals up to five times.

 All of the Fork Seals & Dust Seals are made from the very best 'Low Stiction' material and where applicable are triple lipped and double sprung. The seals have been developed specifically for motorcycles and will out perform most seals on the market including OEM.

All of the fork seals are made from the very best 'Low Stiction' material and where applicable are tripple lipped and double sprung. The seals have been developed specifically for motorcycles and will out perform most seals on the market including OEM Seals.

The Red Rubber Grease, when used correctly this grease will greatly increase the life of your seals (up to 3x OEM in our trials).

Note: The Red Rubber Grease is specifically designed to 'Grab' dust and dirt that passes via your dust seals/boot and keep it there avoiding it getting through to the fork oil seals. We recommend that the grease is spread evenly on the underside of your fork dust seals/boots (not on the oil seals). Do not apply it directly to the oil seals as you don't want dirt kept around the oil seals (stuck in the grease) as this will ruin them quicker.

Kit Includes: Fork Oil Seals (x2) & Fitment Grease 

* Seals only, no fitment grease, supplied as pictured (not from Pyramid Parts) 

The following chart can be used as a guideline.

Considering the age of these dirt bikes, modifications may have occurred over the years, please ensure the the forks are original to the bike, the following chart shows the product number required for the forks original to the bikes. We are not responsible for fitment of seals on forks not original to the bike.
