The manual doesn’t give times or mileage on when to replace the fork oil,oil will degrade/loose its viscosity over time and pick up metal particles from bushings etc.
What’s the feeling with fellow riders on when to change the fork oil/seals?

(It’s Recommend Seals and oils are changed together)

I have lots of experience with the super Tenere forks. But my 'thoughts' are in no way "the rules", just my opinion.

With 100% stock original forks I would suggest changing and cleaning the oil at approximately 15K miles (road) and 10K with a fair bit of (off road) use.

Ive pulled down (taken apart) a ton of stock forks. After 10-15K+ the oil is toast and full of crap. If folks have used a power washer I can tell most of the time because the oil is extra stinky and the spring has rust on it. (DON'T use power washers on your bike)

** one more note: the Super Tenere tends to be hard on the guides. I have once had a major oil leak in one of my forks. I think It started with bull dust (talcum powder) getting up there and then I had a lower guide go south. That material fell down into the seal and all hell flowed out.. Good times. LOL ** If you have your forks pulled down for any reason replace the guides, seals, wipers, oil, Etc. Clean them up and throw them back together. You WILL feel the difference and performance immediately come back.

Once you clean and install a better high quality fork oil a good round number is changing them every 25K or so. (if you want them at there 'best' performance. Just depending on use, abuse, Etc

I keep my forks top notch. Ive changed mine out a few times because of heavy off road use and fine silt "bull dust" having the seals weep. I don't mess around with doctoring them up, I just change the oil and seal. (and other parts guides, etc) I have a fork right now that is slightly weeping and will tear it down (probably the pair) before my next long cross country ADV trip. The fork currently won't keep me from riding around town or weekend rides.

Also, if you change the oil weight and or spring combo. Please read and and do a little home work or talk to someone you feel comfortable with about the forks. Changing the oil weight, the volume of oil and then also adding a change like a new stiffer spring with greatly change the way the bike will sit, ride, perform, Etc, Etc. You might be going from a worn out air marsh mallow, having the proper service work done and front end set up properly and it will be a WORLD of difference. Its not to say the work is wrong, but it will be way different. You might or might not like the "correct (freshen up) set up".... Just have an idea before you start telling someone I want this and that !!!!!! LOL

Ask me how I know such things ? LOL.

Fork oil change every year at minimum, regardless of the miles.

I do mine every winter and then a dump and fill mid season. As stated above fork oil gets nasty pretty quick. Lots of metallic particles in there. Can't do it too often in my opinion.

Thanks for the information Tabasco,I’ve just done a full fork rebuild @80000km, I’ll probably replace everything @100000.The bike definitely feels better after a fork rebuild.

According to my experience is always better to clean well everything before the oil change. For this reason I prefer to remove also the cartridge....lf someone has got dimensions of the holder I can build it...
Thanks
