Why is a twin tube shock better? Ohlins TTX shock absorber stripped

- Have you ever wondered what a twin tube shock is? or why it's better than a normal shock?
Probably not... But if you have Dave is here to explain the differences and strip an Ohlins TTX shock so you can see what he's talking about.
Thanks Dave! A few other advantages of the Ohlins TTX technology is no worry about cavitation and no need to pressure balance. Also, re-valving is much easier than in a single tube shock.
I came in search of pudding & learned about suspension. Brilliantly explained, thanks. 👍🏻
Glad it was helpful!
OEM shocks for street use are adequate for regular use or even some canyon twisty roads.
Everyday is a school day watching your vids👍🏻😁
Interesting and well made video.
Excellent explanation very clear and concise easy to understand 👍👍👍
Great explanation and demonstration of these dampers. Thx
Great video explains the magic that happens inside the rear shock 👍🏻
It makes more sense stripped down and shown like this. 👍🙈
The biggest problem we find with this design.....and it is a big one...Is that the shaft piston area is so so large compared to that of the valve port area. This results in a lot of harshness due to the fact that oil wont compress and it is rapidly trying to accelerate through the very tiny ports. As you would be aware, damping is velocity sensitive and the force rapidly rises on square edge bumps making the ride super uncomfortable. The SBK TTX has much larger pistons compared to that of the consumer model in order to overcome deflection off bumps. Sadly anyone that has purchased a TTX equipped OEM bike may not agree with your adoration of this concept due to the lack of attention paid to basic mathmatics by Ohlins. Most track bikes wont see wheel speeds over 600mm per second but this is easily exceeded on the road.
Good one Terry 👍
In that case what shock absorber would you recommend in high end quality like this Ohlins for the road application only ( not racing).
Everything I’ve read about the TTX being used on Triumphs reflects this. Really disappointing but I’m happy because I have a Penske Double Clicker. Easy to work on for an average mechanic and works great on track or road.
Kind of funny in the bike world you have Monotubes and they sell you twin tubes as a sporting upgrade while on the car world twin tubes are standard and they try to sell you mono tubes as an upgrade
The twin tube shock you are talking about is very different from the TTX technology. Most "twin tube" shocks have a foot valve for compression and are emulsion (pressurized gas mixed with the oil) type shocks. Very old technology.
How do you get the pressure back into the shock on reassembly?
With a nitrogen supply!
@@obsession_engineering just watched your other video with the bicycle pump lol know I know cheers mate!
Dave keep the engine rebuild vids coming they are very good, got a 2005 fireblade myself
how is this design superior to the Rebound Separator Valve by Race Tech, for example?
nicely said mate, simples! cheers.
Have you ever tested this theory on a damper dyno?
I haven't had the chance, but it would make for an interesting test
Who else is wondering here To Spend or Not 1000 for rear Ohlins 🙂
For me I sourced a used ohlins off of a wrecked bike with 2k miles for 350$. I sent it to ohlins USA for inspection and to set it up for my weight and style. All and all it was around 600$ installed and yes I believe it is worth it.
Just got my new Matris for about £700.... but I think a single tube.
