Fork Oil


Recommended Posts

Happy New Year!


I have a question about fork oil. I just installed new fork seals on my 99 RT and now need to put new oil in. Do I have to get official 'fork oil' at $9.00 per Qt or will any high-quality 20w SAE oil do?


What do you guys use?

The oil in the Telelever forks is only for lubricating the bushes and has no damping duties. Fork-oil is a low-foaming oil needed to be consistent in damping performance on standard forks, this is not needed in this application. I use cheap fork oil because I had plenty, but any similar viscosity oil will be good. I know of at least one rider who uses ATF as it has seal conditioning agents so reduces the probability of leaky seals.

Yeah, I've seen AFT cited in the posts before. Looks like I'll be going the AFT route.


Thanks for your posts!
