Sorry for the audio problems. I did my best to fix it and re-loaded the video. Ill try to do better next time

Hello Douglas, your video are very helped me to understand about damping, I have see many videos about damping, but your video make more clearly to understand, thank you sir for sharing your knowledge🙏👍 @TheOhlinsGuy

Damping is what a good shock does. Dampening is what a leaky shock does. :D

great lesson. thank you. will not miss any.

Great video, good to see you again!!!

Great info...............Thanks a bunch.

Hi Douglas, Thanks for the entire series of you videos, I've watched them all and after seeing lots of conflicting information about damping and springs, seeing the actual dyno results inclines me to believe your real-world results more than other jabbawanking. I was wondering if you could do a video on Off-Road (motorcycle specific) video where you can probably talk more about optimising for the small bumps as well as the big hits. Thanks!

Hi Wow you are a glutton for punishment watching all of my videos! I am trying to show how to and not really tell what to do. This is basically because I don't want to talk about things I really don't know about. I really don't believe that there is much difference between off road and on. I think linear damping is still what you want to do and you want to stay away from progressive springs and digressive damping. Remember that almost all shocks are velocity sensitive. There are some shocks that are position sensitive also but even then within those positions they are velocity sensitive. Some shocks that are made for mostly off road have a hydraulic bump stop for very high energy hits but they only come into play at very high velocities. These bump stops usually have shims so even then you want to be linear. So if you have linear damping that works on your bike and are not overdamped , the damping will automatically adjust to the road conditions. If you are on small bumps the shock will not see much shaft velocity and will not put out much damping. If you have big bumps the shaft will see bigger velocities and put out more damping. This doesn't work well with digressive damping or progressive springs.

@@theohlinsguy4649 what can i say, the lockdown's really upped my pain endurance! thanks for the response too, and i was looking for some advice pertaining to a certain uncommon mix of bike and suspension setting: the royalenfield himalayan uses a damper rod and a progressive spring and is targetted at light off-road riding. which change would i make first - a linear spring or a valve emulator? I apologise if this is a little digression from the main topics here, but i would really love to hear your opinion on this. Also, you should make a video on your 50 years of racing, that would be really ineresting! Cheers, Haren

@@Bomberboy92 Hi Thanks for watching! If no Ohlins fork insert is available I would just get an emulator and do the spring at the same time. No use doing one and not the other. Obviously an emulator is a half measure but it is sure better than nothing, which is what you have with a damper rod.

@@theohlinsguy4649 Perfect, that makes sense to me. Just one more question, sorry to throw so many at you but i really appreciate the experience you have. I have a KTM 200 exc ('04) (open chamber cartridge forks) which i recently bought and had had the forks serviced. it was about 6 months later that i got to ride the bike and the damping was way too stiff. A week later, an oil leak started from the bottom of one fork leg , and once it all leaked out the damping was much better (i rode it once with the oil empty in that one leg and it handled much better). Now i'm going to get that seal done up, but how would i go about solving the damping issue? do you think simply replacing both legs with an oil half the vicosity (in CST) would work? or is there more to this? thanks again! Haren

Thank you Sir💖

Ohlins guy, thanks for sharing your suspension knowledge! I have a question. Can we get the same damping characteristic by changing oil viscosity (with some reasonably range) OR by adjusting the bleeding flow by intervention on the compression and rebound adjusters , for the same cartridge fork? In other words if I’m currently using a 37 cst(40c) oil with “open” adjustment and I want to test 21 cst (40c), in case I am not happy, can I expect “getting back” to previous feeling by closing the hydraulics and getting (almost) the previous damping characteristic ? I am guessing the answer “ do not change anything if you are happy “ is not an option for 90% of the people who are watching at your videos! :) thanks and pls keep posting your good information

Hi Federico. I think that it might change damping a bit within a range but it will probably adversely effect your damping in many others. Oils for shocks are different than oils for your car or even your braking system. They perform many functions. Using different viscosities to alter damping is just a way to get around doing it the correct way which would be changing the valving and bleeds if you don't have any outside adjusters. Ohlins has a great paper explaining what goes into making Ohlins oil. I will attach it to my KZread pages as soon as I can figure out how to put it on my web page and link it to my KZread page. Ohlins has different oils for different damper uses. I basically use 2 Ohlins oils, 1304 for auto and 1309 for motorcycles. I guess the answer is that I don't know because changing damping with different weight oils is not something I do. Also I am all for trying things and see what happens. That's how you make progress. But playing with oil viscosity, in my opinion, is not a path worth going down.

Hi, thanks for your replay. Of course we are considering only forks'oil in this discussion and their different viscosity (1309 ohlins has 19cst @40c so is rather "thin" if compared to my Honda OE application which is 36 @40c). The reason why I am into this is because I was going to buy Ohlins FPK 3200-01 (front fork valve kit which is hard to find in Italy) but their Sales dept in their main office in Sweden discouraged to fit on my application because was never tested (my old CBR 900 '97 with 20mm fork cartridge). So while I appreciate their professional approach, on the other side I am continuosly trying to rise the bar.. Possibly this Ohlins kit would work fine in my case but I had to buy another pistons kit from another brand and they suggest 22cst. Of course viscosity has to be considered as only one variable of the system (pistons design, shim stack and thickness etc). So at the end of the day, I have an aftermarket kit installed by authorized dealer but unfortunately the shim stack configuration was not disclosed to me (I've disassembled and measured but I cannot confirm this is what the mother factory reccomends). But at the end of the day the question is : does fork cartridge work better with low viscosity and "closed adjustment" or better with "higher" viscosity and more "opened" ? thanks

@@federicob7521 Ohlins has thoroughly tested shock oil. Remember every successful Moto GP team is on Ohlins. I have decided to just take a video screen shot ot the Ohlins paper on oil and post it on my KZread channel. It is a few pages long so you will just be able to pause the video to read it. I should have it on in a few days. Thanks again for your comments!!
