Tearing into the forks of a motorcycle to replace fork seals or fork oil can seem like too big of a job for a lot of people to take on at home. But learning how to replace them yourself will save you tons of time and money over the course of owning your bike. In this video, Charles shows how to properly replace fork seals and oil on KYB PSF 2 forks from a 2015 Honda CRF450R. These forks will also be found on 2015-2016 Honda CRF450R and 2016-2018 Suzuki RMZ250 models.

[@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!

[@rojmufty1655]

Thanks for making this video!!

About time!!!

[@michaelmelton1578]

Thank you for the knowledge to college.. appreciate these videos

[@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!

[@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.

[@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?

[@LiLLobby]

Great tutorial! Thanks!

[@rmatvmc]

Glad it helped! -Charles

[@garyjohnson7697]

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.

Are these the forks for a 2002 yz125

35 psi,is standard for work?

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?

Like if you’ve had to replace fork seals👊✊

Nobody wants air forks

[@rmatvmc]

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