I must have watched this video 30 times already. You sir, are amazing at explaining this stuff. Your animations are amazing, you speak slowly and concisely and pause so that the information can "stick" in my brain. THANK YOU for your work on this topic! I was able to revalve my own suspension and the results were amazing!
Thank you so much for the amazing feedback!!! 🙌🙌🙌 that is exactly the goal of these videos, to help the average joe understand what has been considered too complex to do 💪 you sir, just made my week!
Im 56 and have done my own suspension last 40 years. This video is by far the best one I have ever seen. I knew only 50% of what you show. Excellent done 👍🏼🙏.
This is exactly what I needed! I once dreamed of working in the suspension industry but was met with gatekeepers and old salts who bragged about how great they were but wouldn’t share. It totally turned me off of it. They lost a capable successor to their business. Now I work in a different industry and am happy to share with others just like you have here. Cheers!
Best tuning video ever! The quality of your videos are second to none. Thanks for helping us guys that like to do our own work but don't always have all of the information.
Outstanding!! I had some idea how this works, but the animation with the graph towards the end really puts it all together to achieve a desired result. 👍👍
I Have to hand it to you. I've been doing suspension for going on 30 years. I've never seen an explanation so clear and (this is what I find extremely rare) accurate information. And your point about changing the shims is the easy part. Knowing which shims to change to accomplish what a rider needs is the hard part that only experience with different suspensions and different riders will take decades to learn. Great diagrams got your point across perfectly. Very good job, guys!
Thank you so much 🙏🙌 I really appreciate it, specially coming from an experienced tuner 😄💪true indeed, knowing what you can change is one thing, knowing which one to change is another ball game that only experience will get you 👌
@@StepstoPodium But you did give us enough info to see where we are at and pick the most reasonable part to try changing. *How far/how much, well that will take exp, but at least we have the right map to work off of now.*
Thank you for this simple explanation. My 2022 WR450F is far too harsh for trail riding. I did a 150 mile ride last week and I was in agony for the second half and I still have shoulder pain. Having too much damping is dangerous because it leads to early fatigue which leads to more mistakes or whiskey throttle.
Thanks very much. The principle is quite easy, but the detail isn't. Every explanation helps. Your vid is easier for me than reading. Thanks again, very useful.
Excellent, nice clear information. I love the combination of the changes to the animation on the left being reflected with animated changes on the graph to the right, makes it very intuitive!
Thanks for providing a basic understanding of shim stacks. It makes a lot of sense now why tuners who have a lot experience are desired. The principles seem relatively simple, but the application is difficult!
I truly appreciate it Borja 🙌 it means a lot! If you have further questions regarding this topic (and if you wish to support the channel 😁) we have technical sessions available 💪 www.stepstopodium.com/technicalsessions
I now feel like i could buy shims and get a bike to superb on a budget. Thanks so much for putting this out there. This video deserves a sticky on TH-cam
The visual graphs and sliding things around as you changed aspects made this much easier to understand. I feel like I could now go out and buy shims and improve each of the bikes I have owned. (something I could not have done before)
@StepstoPodium I have to admit that I finally made a change to soften my KYB 48mm forks for the better on trails \ rough terrain. *This ~miracle was accomplished heavily due to the examples towards the end of this video where you show what the slightly different shim configurations make on the overall action of the forks.*
@@StepstoPodium My fix revolved around that cross-over shim. Out of a 12 shim only 'straight' stack, I removed 2 large shims off the top, then I placed a small cross-over shim 5 notches down on the low-speed side and then removed 1 shim from what you called the high-speed stack and got the relief that had eluded me for decade++. -- I have 4 sets of the 48mm KYBs, all on my 2008 - 2012 Husqvarna 2t and 4t dirt bikes. Might do each just a little different since I have a clue now on these stacks AND the compression valve can be removed from the forks WITHOUT taking the fork off the bike. -- Their valving just screws right out the top and the mounted forks with only the handlebars needing to be removed.
This is fantastic! I just watched it about 3x in a row. Feel like I learned more in this half hour than ever before. Thanks for the simple, quickly understood explanations and coordinated animations! Now to watch the others! Definitely subscribed!
Agreed. I have learnt a LOT in the last 3 hours watching your various videos suspension, power valves etc. Thanks a stack and keep it up! I have a lot to catch up after just subscribing.
Hey man, I do really love your videos. They are by far the best in production and with the biggest scientific background on TH-cam when it comes to suspension. Maybe you could one day make a video about other damping technologies like for example Cone Valve. Please carry on with your video production.
Hey Constantin, Thank you so much for that!! I really appreciate it 🙏 I'm waiting for a reply from the folks at WP, but that is the goal! 💪 luckily I already managed to get in touch with the guys at ZF Sachs and soon I'll do one just focusing on their Seperate Function Forks (which is similar to WP technology as well). Thanks once again and I hope you check some other vids from the channel 🙌
Great video on what is often described as a "black art" of mystery....You have helped me understand the relationships of the shim packs to their effect on dampner performance....Thanks for making this great video! 👍
Great explanation of a complex topic. Much better than anything I found so far. Still a normal user should not think it is easy to figure out the right modification. It should be left to experts. Instead of try and error expert calculations are much more efficient. One thing is not correct. Single stage shim stacks do not create a linear relation between stroke speed and damping force. The relation is degressive, creating too little damping in large movements etc.. Two stages can linearize the relation. Or a combination of valves (basevalve single stage and midvalve with float) --> a great source for such information is the Restackor software and related documentation internet pages.
Thank You for this video! This is amazing! Even a bone-head like me finally understands the meaning and purpose of shim stacks and valves. I would add one thing though. The explanation of slow and high speed damping, that it is not about bike's speed.
Thank you for posting this video. I didn’t fully understand the transition between low and high speed stacks previous to watching this. I really appreciate it. Now you need one for rebound which applies the same principles in reverse! Haha
Great video, there’s a lot of videos out there that generalise but don’t go into this detail. I would love to see a video on how after working out your damper rates you would translate it into the shim stack build. Awesome video 👍🏻
Thank you!! Go for it 😁💪 if you have doubts, you can schedule a technical session and clear all your doubts 1-on-1. Check it out here if it makes sense for you 🙂 stepstopodium.com/technical-sessions/
First time I've seen this explained simply and easily. Now I will have an idea of what the suspension tuners are doing when I take my 890 adventure forks and show to get tuned. It's far too harsh on the road.
great stuff .... just doing racetech valves on my KTM ...... now i'm kinda understanding the shim stack .... really good tutorial and illustrations...... this stuff isn't really the black art voodoo that all the big $$$$ tuners lead u to believe...... u just gotta experiment some .... but ur shim stack illustrations are really good !!!!!
Thank you so much Peter! I'm really glad I helped you understand it 💪💪 they make it look like voodoo if they prefer you don't know it or if themselves don't know it well 😁 but that's my 5 cents 😛
God fucking damn bro, I didn't expect this much knowledge dropped on me. MX isnt my discpline at all (as much as I respect it though), but this is so much transferable knowledge to street/track riding and its invaluable. I'm looking at setups completely differently (and how CHEAP freaking manufacturers are 😂) THANK YOU
Hello, congratulations, great video!! , very educating and easy to understand all the concepts, but there's one that I've always thought it was the other way round, I thought that the bigger you go in diameter the stiffer is the stack, I do understand that it's more difficult to bend a smaller one, but in the other hand, the biggers one above have got more room to bend then can flow more oil, would you be so kind to clarify me that point, please??. Thank you very much
It's not a matter of space above, it's only important how the shim setting is made up! Remember, the tapered shape is to reduce permanent distortion of the shims, nothing else. The shim stack works like a spring :)
Something I am wondering... always thought your high speed effected your square edge bumps and you low speed was your jump landings or hard hits I guess I was wrong?
I'm trying to soften my 48mm KYB forks and finding out how little I actually know, even after getting a clue here... Seems easy, right?... -- Just removing those largest shims (Maybe 12 in all removed) off the top of the stack had little effect on the damping overall. The springs in these forks were 2x too stiff and changing them helped lots, but I want more plushness at my age now ...
Love the video, really informative. There is just one thing I don't get, shouldn't the slope of the high speed compression be smaller then the slope of the low speed comrpession? Don't know much about suspension, so I might very well be wrong
If you don't have more damping generates as the speed of compression increases, it will blow through the stroke. Remember that speed of compression has nothing to do with suspension stroke used.
@@StepstoPodium Thanks for the quick reply! That makes sense and I get that we are not talking about the stroke, just the speed. I thought that the high speed compression was more like a pressure release. The damping would still increase/velocity but not as quickly as in the the low speed. I haven't watched all your suspension videos yet, but I definitly will! If you haven't touched the topic yet, I would be really interested in knowing which scenarios are high speed and which are low speed For example is braking low speed but an emergency braking scenario high speed? Of course it all depends on the setup but some idea of where to draw the line would be interesting
@@StepstoPodium Of course,I have a little question, is it ok to have only 3 same size shims on my suntour rux 38 fork ? According to a guy servicing it by himself this results in faster wear. What do you think ?
That question is too specific for me to be sble to answer correctly... do you think scheduling a technical session would be benefitial? You can check it out on our website :) www.stepstopodium.com
Wow best video on the subject, thanks for that explanation. I have a question, what would you recommend to change on my shim stack? I ride an Enduro Honda CRF230 with an XR250R fork (compression damping Adjusting only), and my Racetech Shimstack is as follows 8 shims .10x17 crossover .10x11 one .10x17 one .10x13 one .10x9 one .10x8 My clicker is already completely open. The Low-Speed feels Ok, The High-Speed damping could be a litte softer What would you change so that i can close my clicker more (to have more adjustability) an make the high-speed compression a litte softer. Thanks for your advice Greetings from germany
Thank you so much! Maybe reduce the diameter of the clamping shim. Try .10x7 and so on until you have a good result. There's nothing like giving it a try!
@aaaaaaaaaaaaaaaargh agreed. Especially when the rider is heavier or lighter than the "standard". On my KX the stock front springs were rediculously soft. I looked them up. According to racetech, they were for a 130lb rider. Rear spring was 160lb. I ended up hiring a guy that has been doing dirtbike and sled suspension for 20 years. I told him I wanted gold valves, and he said that he could make the suspension work just as well on stock valves, and it would be cheaper. I told him to just put a GV in the rear just because. Anyways, I love riding that bike now. The suspension fixed an understeer problem, and obviously bottoming issues.
So when adjusting clickers you are controlling flow through the low speed orifice increasing or decreasing the amount of fluid forced through the valve and shim stack correct?
Hello great video I am learning about this stuff I am wondering about frepiston can you make it shorter and get more softer stroke before midvalve takes over best regards Brian
Thanks for the answer is it filling the chamber with a stop or is constant working up and down? I’m thinking of doing your online course is it basic setup,I like to learn more about shims on Kyb best regards Brian 😊
@user-ik2ed4dl3g it goes up and down according to compression 💪 It is about all the different adjustments you can do, without having to disassemble the forks!

That makes sense and I get that we are not talking about the stroke, just the speed.
I thought that the high speed compression was more like a pressure release. The damping would still increase/velocity but not as quickly as in the the low speed.
I haven't watched all your suspension videos yet, but I definitly will!
If you haven't touched the topic yet, I would be really interested in knowing which scenarios are high speed and which are low speed
For example is braking low speed but an emergency braking scenario high speed? Of course it all depends on the setup but some idea of where to draw the line would be interesting
@@ThiloK9 if you check out all my suspension video, I believe you'll get clarified on that :D
Now make one on the rebound stack. I need help with that more than anything.
Amazing explaination, amazing, thank you very much
Thank you for watching and don't forget to share with your mates 😄
@@StepstoPodium Of course,I have a little question, is it ok to have only 3 same size shims on my suntour rux 38 fork ? According to a guy servicing it by himself this results in faster wear. What do you think ?
That question is too specific for me to be sble to answer correctly... do you think scheduling a technical session would be benefitial? You can check it out on our website :)

@@StepstoPodium no it’s ok, I will first check what this stack imply’s on a staking site, but thanks for the proposition
top ... please produce more of this technical video content 😁👍🏻👍🏻🎈
Thank you for watching! Will do!!! 😁
This guy is smart!!
Excellent video! Thank you!
Thank you for watching!! 😄😄
Really great info, thanks for this
Thank you for watching! 🙌
Wow best video on the subject, thanks for that explanation.
I have a question, what would you recommend to change on my shim stack?
I ride an Enduro Honda CRF230 with an XR250R fork (compression damping Adjusting only), and my Racetech Shimstack is as follows
8 shims .10x17
crossover .10x11
one .10x17
one .10x13
one .10x9
one .10x8
My clicker is already completely open.
The Low-Speed feels Ok, The High-Speed damping could be a litte softer
What would you change so that i can close my clicker more (to have more adjustability) an make the high-speed compression a litte softer.
Thanks for your advice
Greetings from germany
Thank you so much!
Maybe reduce the diameter of the clamping shim. Try .10x7 and so on until you have a good result. There's nothing like giving it a try!
Hi Harald denn letzten shim .10x8 tausch den gegen einen .10x6
My old 96 KX250 was completely transformed with proper suspension setup
Every bike will be better with tuning. Only few people know how to do this.
@aaaaaaaaaaaaaaaargh agreed. Especially when the rider is heavier or lighter than the "standard".
On my KX the stock front springs were rediculously soft. I looked them up. According to racetech, they were for a 130lb rider. Rear spring was 160lb.
I ended up hiring a guy that has been doing dirtbike and sled suspension for 20 years. I told him I wanted gold valves, and he said that he could make the suspension work just as well on stock valves, and it would be cheaper. I told him to just put a GV in the rear just because.
Anyways, I love riding that bike now. The suspension fixed an understeer problem, and obviously bottoming issues.
So when adjusting clickers you are controlling flow through the low speed orifice increasing or decreasing the amount of fluid forced through the valve and shim stack correct?
Exactly 👌
Awesome video thanks for posting.

Hello great video I am learning about this stuff I am wondering about frepiston can you make it shorter and get more softer stroke before midvalve takes over best regards Brian
Thank you!
Regarding your question, no, it's not possible to do that because the cartridge size has the free piston size into account :)
Thanks for the answer is it filling the chamber with a stop or is constant working up and down? I’m thinking of doing your online course is it basic setup,I like to learn more about shims on Kyb best regards Brian 😊
@user-ik2ed4dl3g it goes up and down according to compression 💪
It is about all the different adjustments you can do, without having to disassemble the forks!
