Hey everyone!

 I recently installed a Matris M-05 rear shock on my S2R1K. The shock was designed for use on the 749/999 series of bikes but Jason at Dept. of Suspension told me he had done a few on S2R's so I took the plunge and bought one.

 It isn't a direct fit but was still pretty straight forward. Although the shock I installed is an aftermarket product, this install can be done using the factory 749/999 Showa shock as well if you want to step up to a fully adjustable rear shock on your S2R without the high cost.

 The main problem with the install is the crankcase breather box and the coil pack for the rear cylinders on the DS motors. The coil pack is mounted from the factory just behind the side panel on the left side of the bike and gets in the way of the shock reservoir so it had to be relocated. Also, the crankcase breather box is in the way as well.

 The solution to the breather box problem is to just remove it and install a K&N filter on the outlet on the crankcase. I've seen this mod a few times on TOB so I knew it could be done. Additionally, the voltage regulator is mounted to the breather box so it need a new home as well.

 The problem with the coil pack wasn't quite so simple. The coil pack had to be relocated and there isn't much extra slack in the plug wires to move it very far. I ended up fabbing up a plate out of aluminum to mount the coil pack and the voltage regulator under the seat just rearward of where the breather box was.

 Here is a picture on the plate with the coil pack and voltage regulator mounted to it.

 You'll have to forgive the chips in the paint as I had to remove it after the install to relocate it slightly towards the rear of the bike. I'll get around to pulling it all apart soon and repainting it.

 Here are a few pic of the new shock mounted.

 All I can say is the Matris stuff is beautiful and works extremely well. I took the bike to the track the day after the install and it is lightyears ahead of the factory installed suspension.

 Let me know what you guys think.

Awesome work!  [clap] I'm about to relocate the coil to make room for a Showa S4R shock on my S2R. What did you use to cut the coil bracket off?

Also, how much is the Matris shock compared to say an Ohlins?

oh my. Aside from the coil pack and breather, it is a direct replacement basically right?


this is defintely bacon bacon.

 Thanks.

I actually did't cut off the stock bracket for the coil. It only required that I bend it up and out of the way. I did it this way in case I ever want to put the bike back to stock.

 The best deal I found on the Ohlins I wanted was around $900. That was for the DU333 which has the external reservoir and the remote preload adjustment. The Matris retials for around $1600 but I found a great deal on it.  ;D


 Yes the shock bolted right up, no problem.

Nice! That will make the job go a lot faster for me! [thumbsup]

any adjustment needed on the ride height rod?

Q

 Nope. Both shocks are 305mm in length.

Good Ish Mash.

I need a new rear shock for my S4Rt, and damnit, that Ohlins is over 1K new (the hydr preload adjuster, etc).  I'm gonna see about fitting my stock 999 shock first, but even that would be a HUGE improvement in the SACH (sucks?) POS ducati put on there stock.  Talk about a saggy ass.....

 If you want a good deal on an Ohlins contact Dan Kyle racing. He quoted me around $800 for the DU333 which has the remote preload and the remote reservoir.

 The DU333 is an awsome shock and I was really close to getting it rather than the Matris. The only thing that turned me off was the length of the hose from the shock body to the remote reservoir. It's pretty long and I didn't like the look of it mounted on the frame on the side of the bike.

FYI, the stock xx9 shocks will not clear the swing arm and/or exhaust manifold rear pipe.

Q

Suck a$$...... :'(

 Really? The how did I get this one to fit?

He said stock 999 shock, not matris.

 I know but the shock I mounted on my bike was designed for a 999. I had no clearance issues with the exhaust on the vertical cylinder at all. I guess it is a possibility that the stock shock is a little different than the aftermarket one even though it's designed for the same bike.

I believe he was talking about the 999shock on the S4Rs not the S2R1000. I assume the different heads require a different header pipe setup so the 999shock wont fit.

 Maybe, But I do know that Q has an S2R800 so I can't imagine he would be referring to an S4R.

this guys post?

this is my next mod. 999 shock. cheepie too.

 Ahhhh. I must have missed it. Sorry.  [bang]

Yup, it was me.  I'll have my bike back tomorrow to confirm the 999 shock not fitting because of the header pipe.  It's hard to drop 9 bills on a shock for me anyway.....

Might give me an excuse to go ahead and build the exhaust I want, so I can use a 999 based shock :)

Im hoping you mean you dont want to pay 900 on an matris!

Now if your going to off that 999 shock you give me a price and let me know. im very intrested i just need a reason to not pay of my credit cards!

 According to your sig you have an S4R right? So I'm curious why you would replace the fully adjustable shock that came with the bike?

S4RT, not S.   I'm a firm believer in having the suspension set up for you, and not some generic #.   Buy the non-ohlins bike, and outfit it to your specs....besides the stock ohlins stuff is built to a much lower "price point" than the Ohlins you buy from Ohlins.   In mayn cases, for much less, you can make the stock showa stuff work better than the ohlins by having it re-sprung/valves for you.

The S4Rt comes with an adjustable POS SACHS thing on there.  No one will touch it as far as revalving it.  Several people have had them apart, and a few say that different shocks were put together with with the piston inverted, parts missing, basically bad quality control on sachs part.

$870 is what Dan Kyle quoted me on the DU333 for my S4Rt.  It's a nice piece, but I've already got a spare showa rear shock for my 999 laying around, so this looked like a good opportunity to have it re-sprung/valved, and use it instead of spending almost 900 bucks....

Fitting the 999 shock may still be an option, as I'm on the fence about making a custom exhaust (similar to yours Mash).   I'm hesitant because I'm not sure how much, if any, it's going to kill the power....and of course how loud will it be.....

 I never really looked at the shock on the S4Rt but I guess I just assumed it was a Showa. I do agree that having the suspension set up for you is the right thing to do, and that the Sachs stuff if awful.

 Anyway, let us know how this works out for you. I'm also curious to know how much different the exhaust is on your bike than the S2R's. I may have to take a ride down to my dealer today just to satisfy my curiosity.

Ok I just returned from my local dealer. I can't see where installing the 999 Showa shock on an S4R will be any problem at all. The exhaust is in the exact same location at my S2R. The reservoir is located on the 999 Showa in the same place as the one on my Matris so I can't forsee a problem anywhere.

 Post up some pics after you've got it installed.  [thumbsup]

A quick glance and there isn't any reason why it shouldn't fit.  If anything, the resivior is angled further back, just like the Matris you used, than the stocker.

As long as there arn't any big differences with the frame/pivot point (same frames?), then this should be a bolt on affair like your bike.

It should still be re-sprung to fit my weight, but it should be loads above the sachs crap, and it will let me put 8 bills to another part of the bike (or the 999 track bike.....tires :) )

Mash, what is your weight w/gear...  I'm thinking the spring on this one is to soft as well....I heard the 999 is sprung stock for ~175lb rider.

 I'm about 220 with full gear. The spring is a bit soft on the Matris but I'll deal with it through the end of the season and I'll send it to Jason at D.O.S. and have him install the new spring. I'm planning on powdercoating the swingarm over the winter anyway so the shock will have to come out for that.

As suspected, it fits without issues to the exhaust. 

As you pointed out, the breather box must be replaced.  Right now I'm working on a good solution for that. 

I'm not sure if the box is nessicary to keep oil from finding a way into the airbox, but I'd like to find out before I scrap it off the bike.

 I just used a K&N crankcase breather filter # 62-1360 and removed the box completely. I've had zero issues thus far and it's been to the track.

I'll check around with other testa owners and see what they have found.  I'm not discounting your results, I'm wondering if the 998cc motor and reving to 11k will make a difference.

there are 2 negative side effects to the crank case breather mod.

1) if oil spits into your airbox, there is no way for it to go back into the engine. You would need to clea nit yourself, or it would eventually get sucked into the intake and burn with everything else.
2) if oil gets spit up the crank case breather, it might end up on your engine, rear wheel, or anything that the exit hole is pointing at.

There was also the case where there was gas comming out of the crankcase (looked like steam) because of some reason i cant remember.

I thought about this issue, and figured the best way would be the mount the crank case breather with a U bend in it to catch the oil, or some sort of sheild around the filter. For scenario 1, the only instance where i ever ha oil spit up the breather tube is when im over filled on oil. This has happened only twice, both when i was 1/2 quart over filled, one was a 95 900, and my current 06 S2R1k. So i dont think it would be that much of an issue.
