Fork Seal Question - October 13, 2016, 02:00 PM

Using the .net phone a friend feature. The fork seal on my Tiger 800XCX is blown. I called the dealer and replacement is not covered under warranty. I would like to replace it myself, but I've been searching the internet and haven't been able to locate any information about the fork. No replacement seals, no spring rates, no oil weight or level.

Any one have any ideas or suggestions? Should I just take it apart and measure the seal to identify a replacement?

Google says they're Showa 45mm upside down forks.

Hit bikebandit.com for part numbers.

Get the SKF green seal kit. Much better than OEM. Less stiction, long life.

SKF part# KITG-45S - You'll need two kits to do both sides.



Edit: Oops. I see you have an XCX, not an XC.

The XCX should has 43mm WP forks, not Showa.

Looks like the SKF green seal kit part# for the 43mm WP forks is KITG-43W. But you'll want to verify that before ording if you decide to not go OEM.

I would go with the skf seals. They are the best period! We sell them at RNR cycles.

Is it that difficult of a process? One of the seals on my daytona is going out apparently. But I think I'll swap the Racetech forks from the speed triple

Racetech sells a nice book --> The Suspension Bible. It's about $30. It will help you through most basic suspension activities. Fork seals aren't too difficult if you are mechanically inclined. But it is typically a bit messy, and you might need a few tools you don't currently have.

I do my own suspension. Spent around $500 or so in tools to be able to do front and back for my bikes. Saved far more than that each year. Good investment.

Thanks for the tip. I'll look into the book

Kinda like doing chain and sprockets...specialized tools that the average end user doesn't feel like buying....but will pay for itself with repeated use.

Its a matter of whether its worth your time and initial investment into those tools. Time vs money.

Correct. For fork seals, your tools investment is likely minimal. And in some cases would be effectively zero. The ones that come to mind are fork cap tools, large hex to remove damper bottom bolt, and sometimes a clip to hold the fork spring.

I did have to grind an open ended wrench to fit the internal nut for a set of forks. Again, minimal cost as I already had the wrench and grinder.

Having the right tool makes it simple.

Thanks for the answers everyone. I should've mentioned that the XCX has 43mm WP forks. I pulled the leaky one apart yesterday and it was cake. Standard USD open chamber fork from what I can tell. No installed preload so I didn't even need to use the spring compressor.


I ordered the SKF KITG-43W fork seals based upon the recommendations. Since I already have the forks apart I was planning on putting them back together with slightly stiffer springs and slightly heavier oil (10w), to support my fat ass. These being somewhat off-road forks with twice the travel of other forks I have worked on, I have no idea what spring rate to go with.. On a street bike of similar weight I would use 1kg/mm springs. I know I need to go way lighter than that, but I'm not sure how much lighter. I'm open to any suggestions about spring rate, oil weight, and level.

Opted to do a motor swap after taking a close look at the motor and calculating parts costs. Found a good deal on a used motor out of a wrecked '14 800XC due to show up at my door today.

Right on. Did you order the motor from Ebay? I scored a GS500 motor for $240 but had to drive 8 hours roundtrip to pick it up from Ohio.

955i motors are pricy. In the $800 - $1000 range.
