Anyway, a couple of those guys swear on this DIY compression stack revalve:
- remove the compression valve from the forks
- measure the OEM comp stack shims, mark down the order, diameters and thickness of each shim
- the magic: change all 0.15mm thick shims into 0.10mm thick shims, keeping otherwise same diameters and order
- re-assemble and enjoy the plush ride
I have a 2012 690 Enduro (250mm travel)and have had the front forks partly re-valved. I weight 78kg in my birthday suit. Haven't ridden it yet, will do tomorrow and let you know my findings. I had told the suspension guy that it was too harsh on the trail, ruts, bumps, stutters/corrugations. Worked well if you were leaping off jumps but then there was still a bit of harshness about it. So, just the 24mm diameter shims changed this time, suspension guys recommendation, different thickness and qty.
Shim setup:
Was-----------Now
24 - 0.15 -----24 - 0.10 x 2
16 - 0.10 -----16 - 0.10
24 - 0.15 x 2--24 - 0.10 x 2
20 - 0.15 -----20 - 0.15
18 - 0.15 -----18 -0.15
16 - 0.15 -----16 -0.15
14 - 0.15 -----14 -0.15
9.5 - 0.30-----9.5 - 0.30

Update:
Took the bike for a ride and now the front forks go up and down when riding over corrugations/stutters. Woohoo!! Finally suspension that works. I can start to hold a line going around gravel roads that are corrugated. It's not perfect or "superplush" but it's a start in the right direction.
So will stay with this setup for a month or so till I decide what else needs doing.
I do need to ask the suspension guy i used why he replaced the first 24mm 0.15 shim with 2 x 24mm 0.10 shims.
All I can say is if you do not have a 690 suspension guru near by, just get your KTM bike shop to start replacing the 0.15 shims with 0.10 shims.

No idea on the float sorry. What ever is standard i assume. But I will ask him tomorrow.

Didn't touch the rebound stack. Do you have any thoughts on the rebound?

I will be seeing the suspension guy in about a months time so he can check the bike out and advise me what to do even further.

Well i guess the only thing to do is tear into mine and start from scratch and baseline measure everything, plug it into restacker app and go from there

Lowering 690

Hi,

I have a 690 with 40mm Koubalink and about 30mm through the clamps. I need to drop it a further 25mm. How would I do that with the suspension. Spacers,shims, progressive springs.

I'd appreciate any advice chaps,

cheers dave

I've done the same as you. I wouldn't do any more than that. You will lose too much ground clearance. The risk of banging the rear link or the rear brake master is much greater. I'm thinking of changing out the 1 5/8 Kouba for a 1 incher. It will be slightly taller but when I load up the saddlebags and such I'll likely be back to where it is now.

However I do believe that if you call around to suspension specalists you'll find someone that can shorten the rear shock shaft and find a shorter spring. Maybe even the front can be done the same too.

What I would also like is get more compliance in the high speed compression of the front forks. Where does one source the shims? Part numbers?

Adjusting Sag on the 690 Enduro R

The owners manual for the 690 Enduro R has instructions for adjusting the sag for the shock. I laughed to myself when the instructions say to remove the seat and side cover and remove shock. I think they forgot to mention a few other items to access the shock. No instruction for adjusting the sag for the forks. Seems odd. Any thoughts on this?

Fork Sag

On a standard 690 you have to remove the fork caps and either add or remove the plastic preload packers.
Or you can fit the KTM Hard Parts preload adjustable fork caps for EXC

Thanks ktmmitch however those preload adjustable fork caps are no longer available as far as I can tell. I'll adjust with the spacers.
