Ok all,
if you have been sat on the fence over the rear spring up grade go and have it done.
I pulled the shock DES off the bike Friday arvo and replaced the spring 10kg on Saturday and reasembled.
I am 95kg and have the cat removed so the bike it much lighter.
Took the bike out today and it has transformed the bike.
Straight away you notice the rear is firmer and the tyre more planted to the ground. Have better drive out of the corners.
Once I got going sport riding and started to throw it into the corners the bike holds it line and is rock steady, it is so confident inspiring I just kept pushing the bike harder, what a ride I've had.
This is what the bike should have been like from the start, it's night and day!
Even though I haven't had the front done yet, that's getting done Wednesday with the shim replacement the bike is fantastic. I'm starting to wonder if the front needs the heavier springs because the rear has made the bike feel that good.

Even if you are a conservative rider but go touring with luggage or pillion or both it's worth while having the upgrade.

After awhile I did pull over and change the setting on DES rebound and compression to smooth it out a bit more. I am quite happy, very happy with the up grade.

It's a completely different bike, no more wollowing and bottoming out rear.
The bike is very stable at speed, corners like it's on rails and is very confindent inspiring, so there you have it, one happy guy!
I would like to hear from someone who is about the same weight as I am and has had the front done as well to hear there comments on both please. :D:D:D

Use the Force.

Good to hear you are sorted with the 100nm rear. Now you may know what others have been attempting to inform you about the 100nm spring.

As far as the 100nm upgrade goes with the Ohlins ttx-ec if you (anyone) think(s) you need a heavier, longer, more robust spring for the rear you may need a different motorcycle.

The rear 100nm is just where it needs to be for me at 270lbs geared solo. In addition, the DES settings allow for a nearly outstanding ride up to and lightly beyond the GVWR of the 1200.:)

Sorting my front springs at this moment. Going with the 7.0's as I only feel the need to eliminate the excessive front end dive under braking.

Many do seem to appreciate the stiffer rear spring, however I noted that those who report favorably never mention riding styles other than sport or presumably good roads. What I would really like to know is how the heavier sprung Mutley does on rough road and bumps? I have no doubt that stronger springs fore and aft may help the bike slice the twisties with additional confidence; however does this come at the sacrifice of getting your kidney stones broken up when traveling rough roads?

Our roads over here are nothing short of goat tracks, the tar is 50 years old so they are rough. At my weight 95kg the bike ride the bumps extreamly well. Add a passenger and I would say it would be plush.

I just finished doing the 100kg rears and the 7.5 kg front spring the combo is near perfect for me. The bike feels much more stable at higher speeds.

Am I wrong in saying Greg Tracy killed the Pikes Peak climb in a Ducati with stock spring? I gotta think if its good enough for him and a world record, it's gotta be sprung about right for that type of riding with riders ~180lb and under. No?

Johnny, congrats on handling the change yourself and thanks for the report.

Interesting you can't add any more base preload if needed, but I suppose that could be sorted with a spacer if necessary, or by sourcing a longer spring from elsewhere.

That is assuming anybody would want more than you have. Might not be needed. You sound happy.

Any chance you could supply us with some sag numbers when you get a bit of time and can organise a helper or two? For me, the most interesting numbers would be unladen and laden sag with the adjuster on minimum. But it would also be interesting to get the same figures for the adjuster on maximum.

Bumpy Road?

I think very few here ride the 1200 like a Vespa.

Suspension too stiff for you liking? Welcome to Enduro mode. This is part of what the electronic suspension is all about. While near the end of a 2100mile tour, my internal highway avoidance system placed my Cousin (FJR1300) and myself(MTS1200) on some what some may call rough roads. While in the Hillbilly kind of state I thought to myself at the time "this is a really rough road. Wow! I'm now switching to Enduro mode". As the leader, I decided to pick up the pace all the while giggling my a$$ off viewing CousinFJR in the mirrors. When we completed the stint on the hillbilly highway (1.5 lanes wide) my cousin reported on how the path taken had negatively effected him. I reported back " Yea, that's how I felt before I hit a button and switched into Enduro mode".:D

Welcome to the machine.

Welcome to the machine.
I generally use the enduro mode for the rough stuff and like it quite well. What I wouldn't want to do with a spring swap to 100 Nm in the rear is make the bike too stiff even in enduro mode for rough road riding.

Don't forget you still have 8mm of DES preload.
Once I get the front done this week I'll post sag.

Yes, sorry, that is what I meant. You have adjusted the base preload to max, or so it appears. So the figures that interest me from there are your unladen and laden sag at each extremity of the DES adjustment range.

(If you are using the stock settings, then solo rider + urban mode will give you DES preload 1, which is min; while solo rider + enduro should give you DES preload 16, or max. But I imagine you know this.)

Link here to Andy's DES stock settings spreadsheet in case it helps. (pdf download)

Thanks very much, I look forward to that! Will be interesting.

Jonny what sort of dollars are we talking here mate?
It's not expensive.
The pair of fork springs are $140

The rear shock spring is $105

Shipping is $70



Total $315



My paypal is the same as my email, [email protected]



Thanks, Dan



If you have ever changed your oil on your bike you can do this upgrade.
Parting the rear shock out is no big task, if you follow the cheat sheet and my comments on how to do it.
Once the shock is out just take it to a shop that deals with race bike upgrades and have them remove the spring and install preload because the replacement shock is 3mm shorter, make that known to them so they add preload.

As for the front you need to buy the tool to remove the fork caps. Just hunt it down on any USA Ducati site not dear, it's just a matter of unplugging the DES removing the caps and parting out the springs but you can get diagrams on the Ohlin forks so there is no hidden nasties, all up under $400AU.
If you need any more advice just PM me and leave your number and I can talk you through it. :D

I just ordered up a set of 4802-75 for the front and a 110NM for the Daytona 675 to put on the rear. Talked with Ohlins USA and they also recomend that I add a 21036-03 spring clip to the package to maintain the bikes geometry. Interestingly, this new spring will be 12mm shorter than the original which is why I need the spring clip. Unfortunately the clip is on back order, so a couple of weeks wait before I can try them out.

Static sag

Had my oldest son come around today so I took advantage of it and get him to measure the static sag on the multi now that the new springs are in front and rear.

Sport mode static. Front 130mm Rear 270mm to where we measured.
Ladened with me. Front 110mm Rear 236mm
Enduro mode
with me. Front 115mm Rear 254mm

So just take the numbers away from static and there you have your sag.
I'm 95kg so need someone the same weight to measure stock springs who is about the same weight as me and we can tell the difference the upgraded springs have made in this regard. :think:

Spring Question

Hi, I'm 170 pounds and wanted to know if you guys think it would be any kind of advantage for me to put heavier springs on my PP front & rear? Any advice you could offer would be greatly appreciated.

I just worked out your weight into kg and you are 77.1kg, that was my fighting weight when I was a lot younger.
If you are riding on your own 95% or more of the time I suggest don't bother because you are 20kg less weight than me and I needed to change.
If you on the other hand ride 2 up your going to have to.
Read my latest report in Stock ohlins and rider weight. ;)
