Can you re-valve the stock Kawi ZX-10 Ohlins damper? The OEM one barely works

The Ohlins damper on these 10R are not the same as aftermarket units according to my buddy. His busted the seal after only a Few months and was replaced under warranty.

Not whoring the thread, just keeping it up at the top!

I just called Ohlins... they can't (by legal contract with Kawasaki) alter the stock dampers. The guy I talked to admitted that the stock piece is totally gay!

Anyone know where I can get a re-valve? Patrick maybe?

I never worry about Patrick taking care of me, or anyone I send his way. That's why he's the only one who touches my ride, and always will be!

just a curiosity question cause i have a damper but...i was talkin to a guy at another shop (that also races) and he was sayin that dampers are all but pointless and the only thing they are really doin is covering up a problem with the suspension set-up and geometery. he even went so far to say that alot of racers only have them on for looks cause they are required and that they are either on settin 1 or gutted...now how accuate is this? We were talkin about perfect geometery and what not and did mention that its difficult to get it perfect on the street and some tracks but you can get it pretty darn close (hince the reason for sayin all but pointless.) with that said this is directed to the ones that actually know about suspension setup and not the ones that have one installed and think the damper helped them out...i say that cause i have had my ridden for 4 years now and only just got one 2 weeks ago and dont notice anything different and i do have the suspension tuned (before the damper)

I'll begin by answering your question with a question; What exactly is "optimum geometry" or "optimum suspension set up"?


I'll begin with geometry. Bike model to bike model there are differences such as wheelbase, rake, trail, weight bias etc..
Obviously there is no "magic number" that would dictate "optimum geometry".

Granted, there are guidelines and a range to stay within, but to attempt to say that X rake combined with Y trail is the best / optimum geometry is like saying that there's only one way to make power from an engine, it just doesn't hold true.


What about an optimum geometry for a specific bike?


This becomes a bit more complex. In this case, rider preference and input weigh in quite heavily;

On one end of the spectrum you may have a racer who prefers a quick steering bike that will change line mid corner with little more than a light pressure on the bars, but the trade off is a loose, never completely planted feeling.

On the other end of the spectrum is a rider who wants a rock solid stable platform that he can late brake on without fear of it tucking the front end.
He may have to muscle the bike a bit to get it to turn in and to maintain a line through the turn, but is o.k.with the trade off.
Often times this racer actually prefers to be physical with the bike and NEEDS the bike to be stable in order to ride it the way he wants.

Somewhere in the middle is the rest of us, we like a bike that is fairly quick turning yet stable, so the "optimum geometry" will once again be different.


Another consideration is this, due to a motorcycles inherent basic design, geometry is a fluid aspect at best.

As a motorcycles front end dives and rises or as it rear compresses and extends, it's rake and trail changes dramatically.

How can one maintain "optimum geometry" in this case?

This is one example where a damper can prevent a problem from getting out of hand during the period the bike is at it's extremes geometry wise.


Suspension set up can be just as complex.
Without going deeply into it, one riders style / preference may dictate a stiff suspension, while another's may dictate a more "plush" one. Either rider on a given day may be faster than the other, so once again, there is no "optimum".

Another need for a damper is oscillations or vibrations in the front end. An oscillation caused by any number of things can quickly accelerate out of control, literally ripping the handlebars from a riders hands.

A steering damper can "dampen" those oscillations before they become so severe that they cause an issue.
In this case, neither geometry nor suspension setup have an affect at all.


While I do agree that a damper can "mask" a poorly set up bike, whether it be geometry, suspension or both, it is still a vital part of helping keep a motorcycle stable, even a "perfectly setup" one.


Lastly, as far as a "gutted damper", in almost 30 years of being around racebikes, I've never encountered a racer who had gutted his damper, and quite frankly wouldn't understand why someone would.
Obviously, there may always be an exception to that, but I wouldn't understand the reasoning behind it.

It's all good. I wasn't trying to come across in a negative manner, I'm sorry if you took it that way.
