Ohlins TTX on the new Bergs?

That thing is a work of art.

Is the top, err, bottom a cast piece or does it look like it was put on after. I wonder if they could cut the normal top off rotate it 30 degrees (ish) then reweld. I wonder if that is what coppersmith did.

Don't know IF I would want to take a shinny new TTX and cut it up. Not sure if I would be comfortable riding on it welded either.

I need a ride report.
 
the casting in question seems to have this clevis put on later, however the tolerances and gaps (if any) are very small and I cannot be sure about it...

So you can adjust the preload with out taking off the shock.....

According to some. The coppersmith is the half assed one.... But I am not naming names. :evil:

mmm sorry dont think the extra unsprung weight and exposure to all the crud at the bottom is worth being able to just do the preload with the shock on the bike, it takes little time to take it off anyway

re the Coppersmith mod any feedback you can share ?? be keen to hear of anyones experiences with it :?:
 
Gazza, Today I also mounted my TTX cartridges and noticed that the diameter of the bushing (on the spring cup) is around 3mm less than ID of the lower fork's tube.....It basically does nothing, but still just for info :?:


TTX shock is 1kg lighter than same equipped WP OEM shock.....the exhaust clearance on TTX is better overall besides the first coil of the spring-it goes higher than WP design....the nitrogen reservoir seems to be well hidden ...TTX shock is shorter by app. 3mm or so, but shorter for sure ( I had limited measurements in this area)

great pics

with a link rear it is more practical to have the shaft come out the bottom and extend dowm inside the link/swingarm as space is limited but with a PDS setup there is an option to do things a better way, Ohlin is no fool and there are a couple of advantages to this approach

this is the way shocks should be made with the shaft up out of the crud, I find red desert mud inside shocks, it gets in past the shaft seal as with every stroke there is a minute exchange between the shock and the outside of air/dust with oil

you want to keep the grit outside the shock and away from the shaft, the shiny bit of the shock with the resovoir and adjusters can get as dirty as it likes without effecting the shocks function or reliability, Gazza you sound like a conservative old woman mate :D

I'll put up some weights next time i service my shock but bear in mind the shaft, piston, shims bottoming piston and stem are all made of near solid steel and the outer body of the shock is very thin hollow aluminium so the unsprung weight point gonna be over very little then you have the leverage ratio reducing it by about 3:1, a 5kg swingarm and a rear wheel assy nearing 15kgs so if anyone can tell the difference I'll be very surprised

I see what you mean about the unsprung weight.... It is one KG lighter than the WP though.
One advantage is getting the shock body and reservoir away from the exhaust, mine has gotten hot enough to discolor the sticker quite a bit.

Harry Reed just mentioned something about the new Ohlins design being better than the modified KTM ones. More purpose built he said. I was in a hurry when I wrote that.
 
I was also thinking for the exhaust pipe-my old WP shock was going to really high temperatures. After 1 hour slow ride it was nearly impossible to touch it....I believe this is one of the reasons for highly different shock's performance..I was on the impression that after 30 min break everything was normal again...will see
 
another upside downser but res is at the "top"

too much? nahh as long as it isn"t upside down :D :D

the next step in suspension after TTX will be the computer stuff, maybe magneteriogial fluids and accelerometers on different parts of the bike

an advantage of the TTX with the CSC up the top is you could easily attach a rotary adjusting cable to it. on the fly CSC ooh baby that would be just the thing for desert racing with changing fuel loads

nice clip!

Mate if it's not in the CWA Golden Wattle Cookbook, I dont want to know about it :lol: :lol:

anyhow yeah it seems like the real thinking behind going retro and putting the shock body at the bottom is likely to be the heat management issue, be good to hear someones views from Ohlins on the matter
 
Gazza, when you installed your TTX cartridges did you noticed that the OD on the spring seat bushing is app. 3mm smaller than ID of the lower fork's tube?

Sorry cant help I didnt install them, but will ask
 
Gazza, another question for you: What front sag are you running? ( I know your bike is heavier than normal FE.....there is nothing "normal" though)...My spec. sheet shows around 40 to 50mm rider sag-I am able to achieve it with 6mm preload...
 
Have you ridden it yet? Trail Tricks sent me a set of revalved 08 CC forks to try with my new shock settings. Ran them with 48 springs and an 8.2 rear. Sag was 40/118. I rode it all day Saturday and Sunday at a riding clinic. The forks felt softer than the borrowed CCs I had used previously, but they didn't seem to bottom. Both ends felt plush yet controlled and didn't seem to bottom hard, that I noticed. I was comfortable hitting all the jumps on the tracks we rode, as well as the endurocross obstacles. Over jumping or coming up short on occasion didn't result in terrible things either. 8)
 
I ride the bike every day, but did not make a review since I want to try all terrains I was not happy in...SO far (and there is no reason to think it will change) the TTX setup has nothing to do with my modified OEM WP setup.TTX is behaving so naturally and is extremely predictable-I had not even a single :?: in my mind when hit some stuff. MY common complains from WP was lack of progression since the beginning of the stroke, harsh transition between LS/HS stuff,some unpleasant and weird surprises,too much uncontrolled pitch chassis's movement-TTX solved it!....

BTW my WP fork was modified as per "09 strip.." thread here, my shock was modified to FX specs. with stiffer REB stack...proper springs etc.

When I put TTX I started slowly, but the setup just insist to be pushed hard -the more you push the bigger the smile in your face-amazing and cheap happiness.

I still have to try to reduce fork's sag-now I have 60-63mm race sag with 4mm preload....the spec. sheet requires the sag to be around 50+/- 5mm......as for the shock: 30/115. Even with the increased sag, the fork has no "dive" tendency.....if there was a bottoming I did not feel it....
 
I finally got a chance to ride my latest suspension settings on my home turf this morning. It worked very well. I'd like to ride a TTX equipped bike for comparision...................
 
well, it might be cheaper to come in and ride my bike in our unlimited country..once you are here, you won't go back :bounce3: ..so you are welcomed anytime:)
