Just pulled the non-adjustable forks off of the bike, and noticed 1 leg (left) just feels like a spring when I apply a loaded on it.
I hear fluid in there, and there are no leaks.
Is this normal?
If not, why would they be like this?
FYI: I just replaced the forks, so it doesn't really matter. Kinda just want to know.
Wheelies pot holes. Kinda same thing happened to my left fork, caused by slamming down the front of the bike and bottoming out (wrong springs)

If you took off late model Marzocchis I believe they did some of that...
ducvet can give you more info.
Let me guess it was the left leg. [roll]

Should I assume that:
[roll] = This is normal? ;D
Newer marzocchi forks are using only one leg for damping, the other just helps with a bottoming resistance.
this is on the s2r,sport classics a few 620,695 and probably the 696 as well.
There are many worse forks out there but this is as low as they go on the Ducati's.

Thanks. [thumbsup] I've looked through the ducati parts catalog, and workshop manual, and I did not notice any mention of difference between the left and right fork legs. :-\
I am going to "try" [laugh] to sell the forks, and wanted to make sure they are ok before I do so. [thumbsup]
first set of those I came across I believed were bad so I had the damper waranted. second damper was the same as was all the similar forks I saw later. I got permission from my area service rep to dissect the warranty damper and once I was inside It was obvious that this is done by design.
I'm a little ashamed that I haven't picked up on the one leg thing...
Before handing them over to my suspension guy I bounced the left leg all over my living room and was proud to have found the reason why my track riding damping felt soft/deep/jumpy. Obviously I was wrong.
To match my improved skills I bought better damping and more preload, both still in the same leg. (yes, I regret not getting adjustable forks from the start).
The point of this post is to confirm Club' and to show the pictures of the late 'non-adjustable' bottom and cap.
Also, to repeat that they can be tuned - at least if you're as stubborn and willing to waste money as I am.
Left leg castings: MA64 961
Right leg castings: MA65 960
Cap hex is 19mm

Many of the new motocross bikes have dampening in one leg (Kawasaki & Suzuki). These bikes have very good suspension.
I had a '97 Moto Guzzi 1100 Sport that came with WP suspension. The forks had rebound damping on the left side and compression damping on the right.
Most new qulity forks have compression damping in one leg, and rebound in the other (Öhlins in the newer Triumph triples, for instance).
All of the damping in one leg is new to me, and probably an idea originating from the beancounters. No reason why it should not work, but somehow som potential must get lost ......
Logic dictates that this is how it's done from the factory and probably how my forks were too,
but after my guy's work it's all in one leg.
My guy isn't interested in disclosing all the details, but said something that might indicate that I still have some high speed compession in the left leg. I'm not sure if that's correct - just mentioning it.
So, even if the one-leg-only solution probably isn't ideal (how could it be?) it's working very well.

Well, that's all that counts, really .... [thumbsup]
