How To Replace Fork Seals on KYB PSF2 Motorcycle Air Forks

[@babyXbung]

WOW !! Finally sooo many people have been waiting for this video !!

[@liammacarthur9618]

Rebuilt mine last year for the first time, this video would have been awesome! Rebuilt them again over winter just for the experience. I hate these forks!

[@jtsherry6255]

Perfect video to help the hands-on rider/mechanic! Any tips on fork alignment when reinstalling? I'm told poor alignment will cause premature wear of the seals.. Great video!

[@kennymckim2074]

Where do you stick the fork oil level tool in at? Anywhere in the tube? Just as long as it in the tube and you get air out your good and done?

Great tutorial! Thanks!

Awesome Video - soo simpel. Great job RM 🤙👊

[@spartan0722]

I have the Suzuki version, I cannot find a complete rebuild kit for it, will the Honda rebuild kit work? I assume so, if they are the same fork, but I just want to clarify. Thanks.

on the 2015 crf450 the left side does the comp damping. right side does rebound, so the I'm not sure about the oil fill method being the same. checking manual...says both sides should be at 92mm (3.6") with tube bottomed out. the shop manual has you install the fork back on the bike to pump-eject the air bubbles....(way to slow) so this guy has a faster method.

What size fork seal driver is that? I looked at the RM inventory and the only option for the Tusk seal driver is 46/47mm, I measured my PSF2 and it's 48mm.

[@rmatvmc]

This is a 48mm fork seal driver. You can enter your bike on our website and it will show you the correct size for your bike. www.rockymountainatvmc.com/parts/tusk-fork-seal-driver-p

[@spartan0722]

@@rmatvmc I did, and the 48mm option is not available.

[@rmatvmc]

The bike in this video is a 2015 Honda CRF450R and if you enter that bike it shows a 48mm. What bike do you have?

[@spartan0722]

@@rmatvmc I have a 2013 RMZ250, but the guy that I bought it from changed out the stock forks with PSF2's. I just looked in the CRF450 profile, the driver is there. Thank you so much!!! One more question, the fork rebuild kits, are they interchangeable between the two bikes? I am not seeing any complete rebuild kits for the Suzuki profiles that had the PSF2, but the CRF450 has a complete rebuild kit. Can I use the CRF450 kit in my forks?

Nobody wants air forks

[@rmatvmc]

Race Tech makes a spring conversion kit if you don't want to deal with the air forks.
