OEM vs A-Kit Dirt Bike Suspension Compression Adjusters | WP, KYB, and Showa Shocks

Understanding how to adjust your dirt bike suspension compression adjuster plays a crucial role into how your bike handles over bumps and jumps. However, getting a better understanding on how your adjuster works helps paint a better picture as to how the oil is being pushed through the adjuster. Follow along as JB breaks down each compression adjuster from WP, KYB, and Showa shocks. Be sure to subscribe to the Ride JBI KZbin channel for more Race Recaps, JBI Spec, or Shop Talk Episodes!

Very nice video, thanks! For the future maybe add some close up pictures where people who have never had those things in hand can actually pause the video and look at it closely. Also for better understanding it may be worth to note that the high speed spring plate (WP, Showa) is actually cupped so that it only pushes on the perimeter of the reference shims and puts no extra force on the smaller shims later in the stack. And last but not least the 6-hole piston in the WP Pro shocks it rather new (3 years?) as before it used a piston very similar in port design and area to the stock piston.

Thanks for the suggestion! - Anthony

[@hsilva250]

Great! I guess among all the videos, is the first one that really explains in detail how the high/ low compression works. Thanks 🙏

[@RideJBI]

Glad it was helpful! - Anthony

[@Anstead101]

Thanks JB! Feel like I understand a lot more about the rear adjusters.

[@tfoz2235]

Very detailed and educational video JB. Impressive

[@darrellmabry699]

Great video. Thanks for clearing that up

[@mx724matthew]

This is the most informative video on suspension Ive ever seen. This is awesome. Please do more!🔥🔥🇺🇸

[@RideJBI]

Thanks Matthew! Many more to come - Anthony

[@ChookChasersMX]

Would be great to see how/explain how matching rebound to spring rate is best achieved

[@g-sailing4427]

Hi Brilliant video, could you do a video explaining what kind of jumps/bumps are affected by turning the high speed vs low speed? Thanks

[@RideJBI]

Great suggestion! I think we just might have to! - Anthony

[@lozadazx14]

You’re the best JB 👍

[@Thormxx14]

Great intel.

[@panic-revv85]

Dude, my clickers are maxed on my 23 ktm 300xc. Way too soft for anything fast. I may have to go back and readjust after this vid. Excellent breakdown.

[@lozadazx14]

Can’t wait to send you the suspension of my 23 kx450SR

[@jaysmokey]

The '17 and up Showa shock on the CRF is best shock I've ever ridden. The ONLY negative is the weak rebound adjuster that breaks on the 17's. I believe 18 and up they fixed it.

[@E63s_Scott]

Brilliant & Very informative vid keep them coming please

[@RideJBI]

More to come! - Anthony

[@rogermelling8941]

I have the Wp kit stuff on my kx ..its very very good

[@donovan6717]

Great video 😊

[@RideJBI]

Thank you Donovan! - Anthony

[@greygoose9577]

Great explenation and really easy to understand! Thanks for the video! I would love to see a video about the N10Z shock adjuster since they claim it dynamicly adjusts to the oil flow speed. I don't know if they are common in the us, here in europe i saw them a few times.

[@RideJBI]

Thanks for watching! We will do some research and see what we can come up with on the N10Z shock adjuster. - Anthony

[@richyoung409]

Shake that ass homie! Good stuff, keep up the good work!

[@travelingmike40]

Just rode my Stark and with some clicker changes- that thing tracks . I am interested to know your view/ ideas. Being able to hear everything confuses me a little regarding suspension. I have springs to weight- not sure how much valving will help further?

[@RideJBI]

Hello and thanks for the comment. The stark is awesome. The reduction in rotating mass and vibration goes to show how much a motor (gas or electric) can influence the feel and handling of a motorcycle. Ride JBI has been developing Stark settings for a few months now.

[@randytidwell5836]

will the kyb compression adjuster assembly swap out with a showa like on a 2022 crf250r?

[@RideJBI]

Hello 👋 Unlikely it will be a direct fitment / replacement. Possible with some modifications it could be made to work.

[@briansemder565]

How about explaining KYB shock on Suzuki with triple adjustment. And can this adjuster be replaced with two adjuster type ?

[@ChookChasersMX]

My understanding of the KYB triple adjuster with rebound adjustment up top is a bad idea! We want to maintain fluid pressure not limit it by being restricted from the reservoir. Pressure balance is very important and seems to have been forgotten in the way of making more $$! While it’s not a huge issue it’s nonetheless definitely not ideal!

[@vinceseyb2640]

You didn't speak about the biggest variation between the adjusters which is the effective pressure area being the area of the face shims in contact with the working fluid. The Showa and KYB have 3 times the area of the stock WP. This is why the WP shim stack has to be too light which causes massive flow imbalances. kzbin.info/www/bejne/eYPYYWlrYsiea68si=dwGNGgpx7_pAGRxn

[@RideJBI]

Agreed! Well said - Anthony

[@vinceseyb2640]

@@RideJBI I don't have the scale or platform to make it viable but why don't you make a adjuster piston for the wp shock that mimics the operation of the showa and kyb. If we increase the pressure area 150mm2 vs 56mm2 we can run a stiffer stack whilst still getting it to lift earlier. Management of the pressures would be far better. I run a kyb (16 crf body) wp hybrid with the triple adjuster.

[@RideJBI]

Hello again. You are absolutely correct and thinking along the same lines as Ride JBI. Ride JBI may have already developed and been testing such Comp Adj piston for the WP shocks. JB is excited to share more details as development progresses. Please consider this first video as a way to start the conversation about comp adjusters and to broadly inform / educate the viewers.
