KYB rebound stacks (WP AER)


Recommended Posts

What's the difference between these stacks?

Technical touch recommend 12-14 clicks, but i need to be at 9 to stop frontend from pushing, deflecting or feeling high.

First stack is what I'm running now in one set, second in another set i have. They are for 5.0 springs, sxf 450 2021 ~90kg.

20-0.11*4
13-0.11*1
18-0.11*1
16-0.11*1
14-0.11*1
12-0.11*1
11-0.30*2

20-0,11*4
13-0,11*1
18-0,11*1
16-0,11*1
14-0,11*1
12-0,11*1
11-0,25*2
16-0,20*2

Below i got from another thumpertalk member trying to get along with technical touch valving.

20-0,11*4
13-0,11*1
18-0,11*1
16-0,11*1
14-0,11*1
12-0,11*1
11-0,25*2

As Mog said, all the same. Maybe try backing off your compression a bit?

Consider your shock setting.
A low rear-end with a lot of rebound, or a low rear due to a linkage will take some weight off the front wheel.
That low-slung rear makes the front end feel stiff and makes it push.
Backing out the high-speed adjuster on the shock can contribute to this feeling too.

I don't think your rebound stack is too light, that is pretty normal for motocross.
We run basically the same rebound stack in my YZ125, my YZ250, KX500, a friend's 350SX-F and a FC450-RE with springs ranging from 0.45kg/mm all the way up to 0.52kg/mm.

In my opinion:
A tall riding chassis setting will pitch more and transition more weight from rear to front under braking.
A low riding chassis setting will pitch less and may lack traction in corners.

Thanks. I cant go stiffer or taller in rear, already at 50nm with 6mm preload 104/40, hsc 1.0, 17c, 15-17r. Stiffer then that and it throws me off the bike.

Rebound and comp in rear has been ran through Restackor so it is tuned to suit me. Im gona test 12bar in bladder instead of 10, and then back off a bit of preload (othwerwise i would get 38 static just increasing pressure) and see if that helps.

Front is absolutely to stiff valved from Technical touch. But it is rebound that is to fast right now, not compression.

But only time i have been able to run 12r in front, is when the KTMs linkage screws up and brings up the rear. Done the same now on my 17,18,19.5 SXF 450 bike. 2021 is to new and SKF seals. At that time, i have to back of from 5.5-6mm preload, to 4.5mm to get 104/40 and i can still increase pressure in AER fork from 138psi to 146psi. So weird behavior.
