- Just a few weeks before Covid shut everything down we got a chance to tour the Ohlins USA facility in Hendersonville, North Carolina. In this video Mike sits down Ohlins' Director of Engineering, Christer Looh to take apart an Ohlins TTR 4-way damper to see how it works!

Ohlin's top US engineer broke out in cold sweat when the ultimate enthusiast/geek (in a good way) Mike Kojima started questioning him on regressive damping curves
Awesome video Mike, thanks for the break down!
Spool valves seem so much simpler than shims/stacks.... will we ever see this tech trickle down to the ~$1-2K coilover range?
They didn’t talk about it at all, it I suspect a lot of those valve pieces have complex geometry and pretty tight tolerances which makes them expensive to produce. Shims on the other hand are quite inexpensive to produce.
Always a good day when Moto IQ uploads! Mike, did you ask what he would think to see Ohlins on a drift car?
Hi Mike.
What was the other brand you referred to at 7:22?
27 seconds after release? Dang, I gotta be faster next week
high speed rebound? I think the spring would always rebound at the same rate. not much forcing the weel out.
You’re correct, the spring does always rebound at the same rate. What else would you expect a spring to do? Is it somehow supposed to magically change its rate at random intervals? 🧐 What exactly are you hoping for? And what do you mean about not much forcing the wheel out? 🤔 It’s the same as EVERY shock in existence, the spring is all that ever force the suspension to rebound, so how can you possibly say there’s not much force hen you have zero idea what spring rate they’re running? Super weird comment. 🤪
@@aaronperelmuter8433 my guy this comment is two years old. but ill educate you.
there is highspeed and low speed compression dampening on most dirt bikes to deal with small rummble to hitting a rock or landing a jump. all to deal with the variability on dirt trails.
but on the rebound side its just the spring, there is nothing unpredictable about the spring. whatever spring rate they got is the spring rate they got. so pretty mutch everything has one blanket rebound dampening setting, not split into high or low speed. i fail to see the utility in a split high and low speed rebound, espicly on a shock designed for smooth paved track surfaces.
looks alot like Multimatics DSSV to me ^^
Well it is also a spool valve.
@@motoiq yes and it uses specially designed port-shapes in that spool valve :D
Swedish engineering
WTF? Ohlins is a Swedish company, what’s German engineering got to do with anything?? 🧐
@@aaronperelmuter8433 learnt somethinf new today
@@km6832 Haha, I thought you were having a go at the Swedes or something, lol. Germans know how to engineer stuff but those Swedes definitely know a thing or two when it comes suspension, that’s for sure.
@@aaronperelmuter8433 ohlins sounds german and is on a lot of german cars so its not a bad assumption from me
