Warning on Pyramid Fork Seals, Don't Buy

They looked great and maybe they work perfectly on other bikes, but I would not run their "38mm" seals on a VN 700/750.

I triple checked part numbers with the sales team, ordered, inspected them closely, then installed them carefully on pristine forks. I had one seal that had a small inward ripple in the edge, so they replaced it for free. Cool!

But the seals slid on way too easily and leaked in less than 100 miles. I pulled them, and they measure at least 1mm larger than OEM seals, and I sincerely doubt it's from being installed because of how loose they fit. To be sure, I checked my spare Pyramid seal. It measured the same: oversized compared to factory NOK seals.

Oh, and I did use the correct weight of oil and even made sure not to put them in upside down.

I'm waiting to hear back from the company, but I'm not hopeful on getting a refund.

ya i just ordered their seal kit off amazon and it came in a week ago. . . . great.

Gonna borrow a caliper and get an exact measurement on mine before i install

Also mine are NOK on both the dust wiper and the fork oil seal. BR5481E is the part number on the oil seal, BR2721F is the Dust seal part number also says 39-80 inside of it

I got 37mm ID on the lower wipers and close to 38 on the top rim. My OEM are noticeably tighter, like 35.75 mm lip and the material seemed less plasticy, more rubbery. They were not NOK. Most aftermarket parts use a "low stiction" material which sure, it has lower friction, but it doesn't seal the oil as well from my experience with 3 sets on 2 bikes.

If you got NOK, you might be fine. They're an OEM supplier. Good luck.
