Good day all,

Up for discussion today is my need to upgrade/rebuild & re-spring for my weight the front & rear Ohlins suspension on my S4RS which has an unknown history before me suspension wise.
The bike has just over 40K miles on it. Now I'm coming-up pretty much empty handed as far as aftermarket vendors for my Ohlins forks, I have options for the rear suspension.

But I would rather have a complete solution from one manufacturer, makes more sense to me. The other option would be to switch to NEW components, I was offered a decent price on a complete Matris forks & complete rear spring setup.

Any body on here run a Matris setup or know someone who does? It a major $$ purchase so looking to do my homework before I decide to pull the trigger.
Any and all suggestions will be welcome.

Thanks

You should be able to get race tech springs for the bike and probably a gold valve as well but look first to see if the high speed compression valve needs changing or if it is already a good valve. The drop in cartridges usually work well but often are too close in price to used Ohlins. Front springs are way too soft as is so you will like the change in handing as well as comfort and lack of brake dive.

If you’ve seen any of my posts about my ‘07 S4RS over the past couple of years you know the struggles I’ve gone through to try to get the front end more compliant.
Last winter I replaced the seals and fluid with 5w. I thought that this would be lighter than what was in the forks, but some had the opinion that I should have used the stock fluid again. I believe in retrospect I should have gone lighter, as I don’t have much adjustment left to reduce compression damping and high speed damping is still too stiff. We have abrupt expansion risers in our roads that are challenging for any forks to handle, but I was under the impression that Ohlins forks would be able to handle this. I was mistaken, at least in stock form. Lighter fluid may help this, and I may go back to Ohlins brand.
I had also intended to change springs, but when I calculated the rate they turned out to be just on the high side of correct. Also, in retrospect, I should have gone down to the next rate available. That will be done when I change fluid. At present I’m running the springs with no preload to get the sag at the minimum of the spec. At present I use all but about an inch of travel riding aggressively. I guess that’s ballpark.
If this doesn’t work I’m sending the forks to an expert.

be sure to look at the whole bike. if you have the bike set up tail low you rake out the front and the forks will feel harsh. If you are unable to use all the travel under the harshest conditions try lowering the oil level. Go slow at first drop them 10mm at a time and see if the forks get better.

If you are stuck, sending or talking to a expert is good. But finding a expert near you who is looking at the whole bike is always best.

the oil level spec for the s4rs ohlins is 170mm, i have one customer running 85mm and he's happy with that - he's been playing with it for years and we went up from 95mm previously. think he has a 90 and 95 springs in it.

anyone who does ohlins shocks should be able to do ohlins forks. get them revalved and spring.

I wasn’t mentioning the rear shock because that didn’t seem to be the topic of the discussion but of course I made adjustments back there too, setting for proper sag and also reducing compression damping while checking travel used . It can be difficult to trace the source of a harsh ride, but you can’t reduce the compression damping to the point where you’re using up all the travel.

You should be able to get your Öhlins shock and fork working just fine, no need to buy Matris parts.I found the shock and fork I have on my M800 (and previously on my then.-M900) too harsh, so I have softened the shm set-up considerably both front and rear, and I´m very happy with them now.
I don´t exactly remember what set-up I ended up with in the forks, but I will service them over winter so I could tell later, if you´re interested.

Good day!

Thank you all for your suggestions and personal experiences relating to suspension setup/work...all good for my knowledge repository :)

However maybe I was not clear in stating that Ohlins has nothing for my S4RS other than fork seals, dust shields & fork oil, this information was gathered from from vendors such as Race Tech, Hard Racing and Bellissimoto..so changing springs for my weight or replacing internals is out of the question from Ohlins or other aftermarket vendors :(

Which is why I'm considering buying a complete Matris setup and I was looking for input from someone who is currently using Matris on there ride? It a major $$ purchase so looking to do my homework before I decide to pull the trigger.

Thanks

Hello again.

Just to get matters clear; your bike has Öhlins forks and Öhlins shock, right?
If so, ther are a lot of Öhlins parts that will fit; I use various Öhlins springs for all Öhlins and Showa 43 mm forks; the worst thing that can happen is you may have to make new pre-load tubes.
For the hydraulics, you can re-shim to suit your preferences; re-shimming is also possible if your bike has Showa forks.
Aren´t there any good suspension specialists in your area (as opposed to vendors)?

Hi,

Yes my S4RS has Ohlins front and rear suspension and so far no luck in finding a suspension specialist close to me, still looking..
In the meantime exploring other options & to be frank I would much rather do my our work and add to my knowledge repository ;)

And I also enjoy upgrading/replacing parts as they wear out ;)
I know I can get good $$ for my used Ohlins if I decide to go the Matris route

Thanks
Pete

Try Cogent Dynamics, I’ve heard nothing but good about them. That’s probably where I’ll send mine.

If you feel like doing your own work, the forks are quite simple to work on provided you have a few special tools.
The shock is more difficult to do, not least because you need the nitrogen kit to do it properly.

I will be servicing the forks on my M800 quite soon, I can do a few pics if you like.
For the shock, I can give the shim set-up I´m using and am happy with; try Cogent dynamics or similiar for the job. I don´t know them, but have seen them mentioned on the forumm quite a bit, never a bad word.

i get the wanting to do it yourself, but suspension really isn't a matter of having a play and learning a bit. it's experience with what works and what doesn't and you'll get sick of pulling it apart after you've been in there a couple of times.

I also would call the matris a bit of a downgrade for the bike from the Ohlins, let me explain.

Both may build equal quality parts and then you are down to the recipe and not the ingredients, either one can be changed to suit your taste by altering the recipe. The downside comes from matris does not have nearly the support and track record of ohlins so 10 years from now you may or not get parts, with ohlins I can go back to the 80's with parts availability. Also you have a limited edition bike once you change the visible parts to anything other than Ohlins you are lowering its value (if you care). simple as keeping the old parts to allow swapping back but then you are having to keep track of them.

Elka came to the shop once trying to get us to seel their suspension components and though I did not get to take one apart they look to be similar in build to Ohlins,Penske. Problem was the build causes the price to bu close to the price of a Ohlins or Penske so when faced with the choice 99% of buyers will go for the top tier brands. It is hard to get into the name recognition game but it does matter most of the time. Matris is more known than Elka but is still much more of a unknown than Ohlins,Penske.

Not many people outside of this community will recognize the Matris name so if you’re trying to wow your contemporaries at the local drive in, I don’t see that happening. Ohlins is the big name in quality suspension. If you can’t find local help to tune Ohlins, where are you going when your Matris stuff needs tuning ?

Hi Ducvet,

Thanks for the input, but Ohlins has nothing for my S4RS other than fork seals, dust shields & fork oil, this information was gathered from from vendors such as Race Tech, Hard Racing and Bellissimoto..so changing springs for my weight or replacing internals is out of the question from Ohlins or other aftermarket vendors. I see they go back many years for older Ducs, but not my Monster S4RS :(

And serviceability for Ohlins in Canada is non-existent, unless you have an extreme mountain bike, otherwise you are SOL :(
I guess I will have to live with it for now and replace the fork seals & change the oil (1 fork seal developed a leak)

Hi duc96CR,

Well I'm not in the "drive-in" scene, I ride the twisties & country roads ;)
The only person I'm looking to please is me :)

And serviceability for Ohlins in Canada is non-existent, and probably the same for Matris
So I'm on my own either way!
