TNC, According to MOTO PRO web site, the stock spring is 5.5 and recomended is 5.8 for my weight -187 Lbs. The workshop manual tells me nothing...
I checked my Static sag which is 32mm, This seems high. { Bike sagging under own weight }.
The race sag is only at 63 mm, This seems low. { Me and kit on the pegs } My impression is that the stock spring is way too soft innitially and a bit stiff with me on the bike and on trails. Gives a harsh ride, especially over rocks n roots.
Makes no sence to buy another spring with the standard 5.8?

Any suggestions?

Unlike the fork springs, the shock absorber spring is the possibility of multiple brands: Eibach, DSP, KYB, Moto-Pro, etc. No problems with that.
They are compatible with KX250 springs fitted with KYB, so there is a large market.

Definitely put springs suitable for the weight of each rider is important, but I would like to make a clarification:
When I installed the stiffer springs (fork as in shock) expected a firmer suspension. While it is true that hardened a little, in my opinion was not enough.
Really where I have noticed difference is installing the fork hydraulic valve system quality, as RaceTech or Moto-Pro.
In the shock I have only 5'8kgm spring and it still seems insufficient (weight 185lb). As you can install a GoldValve as the fork to prevent this excess subsidence, lacking in progressivity, as recommended by TNC.

Diverse Spring Company that manfactures DSP had this to say.. Thanks for your interest in Diverse Spring. Our F6161265XX series shock springs will work on your KLX250S. I would recommend a 6.0 or 6.2 kg/mm shock spring. If the stock spring is just a little too soft, go with the 6.0, but if it is way too soft I would go with the 6.2 kg/mm.

So which is it, 6.0 or 6.2 for my weight? 187 Lbs/ 85 Kg

Tough choice.
I am sure with either an excellent compromise reached after completion of preload to adjust the SAG.
Seeing how soft is my 5'8kg I would go for the 6'2kgm. Especially if you do not plan to install GoldValves.

I have an Eibach 6.0 spring...up from the OEM 5.8...on my '06 model. I weigh 190 pounds nekkid and carry a large Camelback, some tools, and other gear on the bike...quite a few pounds actually on my bigger epic rides. I think a 6.2 would be too heavy for me. I do have Race Tech revalving. Jeff, I think my revalve softened up my rear suspension to where I needed the 6.0. Before that the 5.8 felt just fine. And I guess we can't even compare revalves, as you know when you and I talked on a PM about revalving, my revalve may be noticeably different than yours by my riding needs and preferece.

OK guys, I am going to pull the trigger on the 6.0. I will report back after I fit and ride it.

Thanks a lot for the input.

Yes, I think the 6'0kg is a safe option.
TNC that you say is very interesting. I'll remember that when you install the GoldValve in the rear suspension. I'm wishing for it but the birth of a daughter being delayed. I'm going to be a father within a month!
I wait a bit then.
