RaceTech springs question

I'm thinking about putting Racetech springs in the ole KLR. Mainly I just want to get rid of the front end dive when braking. That and it would be nice to get rid of the pucker factor when you come up on a big dip real quick.
Looking at RT site it states the stock spring rate is .40
For my weight, about 200, it states I need .742
That is a huge difference! What rate did you guys choose?
Are you happy with the results? Thanks

If I put that I'm not tall it lowers the rate to .68
I think if I get them I'll go with .70

I just researched that issue. I will go with the .70 springs, but will add their emulators. There are some real good articles on these, and the full discussion and pics race tech web site make sense. The cost in minimal compared to a full suspension change, and, I don't need to make my KLR into my KX450F anyway!
I will get a .80 rear spring, as well and hope the shock adjustment will match the increased performance the fork springs, emulator and changed fork oil will give me. I will add a fork brace, as well. it's a 2012. If you find anything in your research that would be helpful, please post back.

I too have just ordered springs based on the RT calculator. I'm 210 without gear, fairly farkled, and carry some stuff so I've opted for the .70 fronts and 8.1 rear on a rebuild. If I'm unusually diligent I'll post my experience as well! Yay knowledge!

I've got a 2013, for which RaceTech has no info. Is there any reason why I shouldn't use their 2012 calculator?

I'm 6'3", 240 lbs. Racetech says I need 0.718 in front and 8.593 in back.
Little wonder it feels soft.

So I'm definitely not an expert, but I have heard nothing about any major changes to a KLR since 08, so I'd say your golden. As for your suggested rates, seems in line with my suggested rates. I'm getting mine though a local suspension guy (RMR Suspensions, also online) who does a lot of dirt bike work and he seemed to think the rates were going to be good as well. The proof is in the pudding, but either way I'm taking my stand over height back!

THE PUDDING: have now had my Race Tech suggested springs installed for a few weeks. Rear seems like a good choice as per their calculator (though it my stock shock preload adjuster does not dig the spring), but the fronts seem a little stiff, perhaps especially because of the Intiminators as well. I'll ride them for a little longer and will eventually have someone measure the sag for me, but i sense a downgrade for the fork rate in the future.

BTW, another fist pump for the Intiminators. They're magical.

Can you tell me at what level did you put the fork oil prior to installing the springs?
I too have springs on order for the forks and one for shock.

I put them at whatever the factory spec was... FWIW, I talked to racetech and apparently they call for a mere 6mm preload on their fork springs. Might explain my stiff feeling...

Thanks for the quick reply and the extra info on preload from racetech.
