It's always a case of the best you've had is the best you know.

If you've owned many bikes you'll have a list of what they do well and what they don't.
If you've spent any time tinkering with clickers, you'll learn which changes improve things and which don't.
If you've spent any time re-valving your own suspension (or sending it out), you can once again gauge what is improved and what is not.

But it is a total of many variables which often consist of trade and compromise, and finding the balance that works for a rider. You need to at least spend some time to ascertain a baseline (let the suspension break in and evaluate). From there you at least have some data to work with (or to pass onto your tuner). For me personally, I don't need 12 months to do this.. just a few rides to loosen things up.

And! This is what will be important when you find a tuner to work on a newly released set of forks. The tuning principals are the same from one design to the next, but it will be rider information and feedback which will also assist in the tuner getting them dialed in for you. A generic setup from a tuner isn't really that different to a generic tune from a factory. It may just do some things better, and compromise others somewhere else. That may/may not net an overall improvement, depending on what you wish to achieve.

The last set of brand new forks I opened up ( WP OC) had different oil heights by 50cc and one piston with a big chunk of machining slag stuck in it.

They ALL suck right out of the box...

Before you get excited and think that you'll just dive right into the new Sachs closed chamber forks (or have your local guy do them) you'll need to invest in some new tools.

The upper chamber is driven by a 10 point wrench, and the inner cartridge cap separates from the chamber itself with a 39mm hex - 3mm larger than the KYBs.

can a suspension guru give a short concise explanation of the various designs, or put a link to same? The open chamber, dual cartridge, closed chamber terminology is hard on simple guy like me. What exactly is the design and major strengths/weaknesses of the gold Sachs forks coming on the 2016 RRs?

Open cartridge is essentially an oil bath where the oil is together with the air inside the forks in atmospheric pressure.
Under working conditions, the oil starts foaming.
In closed cart. forks, the oil used for damping, is in a closed chamber separated from air and under mechanical load (via a spring preloaded free piston or a bladder). This helps to minimize and maybe eliminate foaming.
When you get foaming, you get air bubbles. These bubbles will create some cavitation as they will disrupt oil flow.
An even worst effect is that when you have a bubble going through an orifice (e.g. piston) instead of oil, you have loss of damping.

So its fair to say that in closed chamber forks, you have far more accurate and consistent damping control.

Rode it in some dirt today for the first time

2016 430 RR Race Edition

The Sach CC forks with the spring change and Race Edition level two upgrades, are pretty impressive.
Still stiff and new, but the forks do NOT flex and bind like the WP's did on the same track (local terraced vacant lot type of track), and they are very linearly progressively damped.

I think this is going to work out just FINE...
