999shock conversion for S2R1000

[Speeddog]

The RaceTech shock spring calculator is FUBAR for  S4 and >'02 Monsters.

TAftonomos, you should have a spring about 11.5 kg/mm if your weight is with gear, 12.0 if weight is without gear.

Just gave him a call. and damn. that guy has some knowledge!

He said that stock ducati shock setups have too much preload. He gave an example of hte 848 which has 25mm of preload and a 170mm spring. Ideally, he wants to put on a 160mm spring to take of 10mm of preload.

The stock 999shock is ~8kg/mm and on an S2R it is ~10kg/mm. I need to find my preload length, ID of spring and length of spring and he will send me a spring that will fit.  =D But i going to see if penske has a shock that will fit the showa since i am looking to change the color of my shock too.

S2R have progressive springs....as do all other Monsters I've seen, other than S4Rs with Ohlins.

Are you guys sure that a 999 rear shock works for monsters with SSS?  It also seems as if the 1098 shock would work as well.

[TAftonomos]

yup, it bolts on.  In my case just the breather box is/was in the way.

 Yes, and no.

 If you have a DS motor, you also have to move the coil for the vertical cylinder if you use the 999 shock. If you plan to try to use a 1098 shock be aware that you will have clearance issues with the reservoir and the swingarm on the SSS. You can use it IF you have the rear ride height cranked up.

I installed a Matris rear shock designed for a 999 and I had to remove the crankcase breather box and relocate the coil. Removing the breather box required making a new mount for the voltage regulator. Here is a link to the thread with pics.

as Mash says, it's a bit different on the 2v's.  My ignition is direct fire, so no coil.  You'll need to do a bit more work, but nothing to hard.

Still waiting to do this mod. My bike is ready to accept the shock. I have everything pretty much ready, aka the coil mount, breather eliminator (just need to get the filter). And then its a drop in shock.  I just keep spending my money on other stuff. Ripped my gloves. $90 to new gloves. need a new backpack...$150 to a new backpack. That was my Ohlins spring + showa shock money 

Other than that, from what i asked around and read, the 999 shock fits the S2R1000 and S4R. the only issues you run into is the spring weight (aside from the breather box and coil). The 999 is lighter than the Monsters and the spring is still very liberal for its "ideal" weight. I still dont know if its sprung for a 175lb rider, or a 155lbs rider. Either way, a new spring is going in, powercoat bright orange, or deep blue.

So it will not work with a s2r800? 

I thought the 800 and 1000 were the same bike but with different engines (not counting the MC's , brakes, and forks). 

For the s4r, I though the frame was a little different to account for the massive radiator and how the engine mounts to the frame. Can someone verify this?  And if so, should'nt a 999 shock work with the 800.  If not, why not?

 Yes, the 999 shock will work on the S2R800. It's actually a little easier because you don't have to relocate the additional coil pack. You will still have to remove the crankcase breather box and relocate the voltage regulator though.

Thank you.  I just got my 999 shock in today.  I figured i had to remove the breather box and the regulator (since the regulator is bolted on the box).  Now i have to figure out how the adjustments on this baby.

It was not easier.  You have to relocate the coil, atleast that was the case on my s2r800.  the two tabs that stick out where the coil bolts onto will interfere with the travel of the rear shock.  If your looking from the rear of the bike (where you are able to see your cluster/gauges) the piggy back reservoir is off set in an angle to the left. 

It was a pregnant dog to fabricate as i had to scrounge around the house but I was able to pull it off.
