Pulled down an 04 ktm 450 exc shock yesterday. They are a lot different. Still 44mm o.d face pistons on comp. but both stacks now use .15 crossovers. The needle is way shorter and almost looks like last years needle just chopped of half way down.It has close to no taper to it. Almost makes me think that there will be no progression once the needle comes into play it will just hit a wall of valving. Much testing and playing to be done. I can post the fork and shock valving if anyone is keen for a look.

Strange...it was my understanding that the 04 needle was to be longer than the older one's and be more progressive? More taper? :think:

It would be great if you can post the valving for the fork and shock. I rode the 2004 of a friend and the forks were really plush compared to my 2003 EXC. I would like to see which changes in valving they did make, and if they changed the midvalve.

Do i understand that there is no rebound shim stack at the midvalve.
(i have only seen mine forks from the inside, marzocchies)

Thanks for your input dbrace! The fork setting looks quite similar to 2003, but I don't know right now which size the clamping shim was, if it was a 10mm or 9mm. Do you know the mid valve of 2003? As the new setting is much plusher...

Prucucuma, so this rebound stack is located at the midvalve piston.
I read this like it is at the basevalve?
I mean mine fork come with a rebound stack at the base and one at the midvalve.

The WP forks have the rebound stack at the midvalve positioned (on the other side of the piston...). At the base valve is only a check plate for letting the oil flow nearly unrestricted back into the cartridge to prevent cavity (read air bubbles). From top down you have:

mid valve (for comp)
piston
rebound shim stack

check plate
piston
comp shim stack (base valve)

I hope this helps...

Oke i noticed that there is no high-speed comp stack at the midvalve. So is there any improvement possible? And the same for the rebound stack in the shock, no high-speed shim stack there either. That is common with WP's?
