Can verify this. My gf's bike with pre load wound out sits waaay lower than mine. Mine has been wound all the way in and she can barely ride my bike.

Can also be seen in my measurements above. with zero preload it was 59,5cm,with max it was 61cm, the rear came up 15mm on the preload.

It痴 been some time testing, and I have covered around 300+km with the new Wilbers system.

Not going to lie, this upgrade is great as far as I知 concerned, money well spent, I pretty much got a new bike.

First of all the feel of the bike is hugely improved, I feel much more confident now.
 Hitting bumps, tears or joints in the road, especially mid-corner is no longer an experience warranting a clean set of underpants.
I知 now much more confident pushing the bike through corners. 
Mind you, I have only 300+km so far, and not only do I suffer from the winter break, but also 10.000km with the old suspension in the back of my head.
 I知 afraid I might get a bit too confident during this season though :)

I had my SAG set up, and for someone weighing 100kg plus gear, I have a lot more adjustment to go, both on the forks and shock.
I have been playing with Wilbers fast/slow compression, and I have found a setting I知 happy with. Pretty much 6 clicks in from minimum for slow compression (30 click range), and 3 clicks in for fast.
 That gives me a rear that is not moving too much during accelerations or when pushing through corners, while at the same time soaking up bumps without sending shocks up my spine.

There have been occasions where I have been wondering what has been going on, as the bike had an odd feel to it, then realized that I was riding on old, worn, coarse asfalt and the odd feel was the feedback from the road surface.

The bike is no longer ォnumbサ and unbalanced in lack of a better term. It痴 now crisp and balanced in a whole new way, I have a good feel for the surface and grip, I dear to ride much faster in corners with higher lean angles than before.
 But most of all, I知 no longer terrified to hit a bump or the asfalt joint mid-corner, I still feel them, but the bike just soak them up with no drama.

The suspension modes, Soft, Normal and Hard are vastly different, to be honest I find myself riding in soft most of the time. In the other modes the feedback is somewhat overwhelming at the moment, I can more or less distinguish individual stones in the asfalt. I have ridden in Normal when riding spirited on mountain roads, but on country roads, motorways, towns and cities I find myself riding in Soft. 

I guess this is what the bike feels like for someone weighing 75-80kg plus gear.

I have found a setting I'm happy with at the moment, but I may end up tinkering a bit more with it as I get even more confident with the bike.

Would I do this again? Absolutely !!

Note: Since I'm not an avid track rider, I can't give a good evaluation on how this works out on track. I suspect it would be a huge improvement, but no idea if it can rival a conventional system.

Good feedback Nog.
Why is common sense so uncommon?

Noggie - thanks for the follow-up Wilbers DDC report, and for your exhaust swap video. I'm doing both when sales of spare moto parts fund the projects... 50% of fund raising goal as last week.

Hi Guys

I sold my bike and have one wilbers with DDC for sale: https://www.s1000r.co.uk/index.php/topic,7634.0.html
It's a good price for a very good setup:)

Thought it was time for another update.

To be honest, I have ridden far, far less this year than I expected and what the weather has allowed.
I guess it's down to an extremely challenging new job that I started in October last year.
Not really a good excuse, but the sad fact is that I have probably ridden a mere 1500km this year, not very impressive for sure, last year at this time I was around 5000km.

These km, while not many, have made me get to know the suspension better and there are some things I have learned.
The tinkering with the setup is far from over, but I feel I'm getting a lot closer to my ideal setup.

SAG was set to BMW spec. approx. 10mm front and 24mm rear.

Rear shock adjustment.
I initially set the slow and fast compression adjustment very soft for maximum road comfort.
That did feel good in the beginning, however as I rode the bike more the something did not feel right when in an upright touring position. Going around traffic circles felt weird, like you were about to tip over and I really did not trust the front.
One time I actually put my left foot down in the city as I wholeheartedly thought the front wheel lost grip through a traffic circle made out of some "fancy granite stones". Was probably not the case, but a really, really uncomfortable feeling.
I then decided to tighten up the slow compression as I though the rear was too soft and the rake of the bike was wrong, this is now approx. in middle position, fast compression is about 1/4 from soft, for comfort.

This helped a bit, but I really could not shake that feeling of not trusting the front. Hard to explain, but the front felt stiff, high and light, where you feel that if you push the front it will just wash out and you crash.
Leaning forward to a more sporty riding position did help, probably because I shifted my weight forward.

I then turned my attention to the SAG. Now, I know to reach BMW spec I need about 4 turns in on the fork and 8 turns in on the shock, both from minimum.
I backed the front out to 2 turns in, and the rear to 3 turns in. Did not remeasure SAG as it was a test.
This had a good effect on the front, it did soften up a bit and felt a lot better.
Could be an effect of the stiffer spring and DDC computer that made the computer set the front overly stiff by adjusting the valving that way.

The additional adjustments on the Wilbers shock is also something that will allow you set the bike up completely wrong.
I have regained some trust in the front, but I suspect I'm still going to be tinkering with the slow/fast compression adjustment on the rear shock for some time. it came from Wilbers with both in the middle position, maybe for a reason.

I'm trying to find a good setup for "Normal" mode and use that as my primary, up to now I have been mostly riding in "Soft" until I changed the SAG and increased the compression adjustments.

Hope this was informative, I'll keep tinkering with it and update.
The season is coming towards an end, guess I have 1-1,5 month left at best, work is crazy busy but I would hope to get another 500-1000km in this year.
