Suspension feels too soft

Did a search for suspension setups for the rear but couldn't find anything. Just wondering what some of you do to take the squishyness out of the rear of the KLRs. It's an '07. Also, what is a good general setting for the front air shocks? I'm gearing up for hunting season so I'll probably do as much off road as on. Thanks.

I think most people put the rear shock on 5 which is the max. I'm 180lbs and use 5 as well.

I also think most people run 0psi in the front shocks. I don't have any air in mine.

How much air pressure should I use in the forks?
The forks will allow some amount of preload air pressure, but are designed for atmospheric, and this is best because it minimizes loads on the seals. In fact, you might get a plusher ride if you sit on the bike, and then vent the forks through the valves. If you need preload in the front, it is best to put additional spacers over the springs.

Same here, but I do have Progressive front springs, which make a world of difference when it comes to front end dive.. $80 well spent..

As far as the rear, there's no easy fix.. Bumping it up to 5 is a great start and it might be exactly what you're after..

I tried it and wanted more.. I put a Progressive rear shock on, but I didn't like it.. Over sprung and under dampened for my riding.. I finally went with a MOAB rear shock made for my weight and riding style and have never been so happy with a suspension in my life.. But it's not cheap, at almost $600..

I completely agree with Wanderer on the front as far as air pressure, and bump your shock up to see if that does it for you, too..

Remember, the bike is made for both street and off road, and it's got a lot of travel for a reason..

Thanks for the fast reply! Yeah, I know they travel a lot but with just me on there it just seems to light (set at 1) #1 is the only number I can see so I'm just under the assumption that it's set at that from the factory. I just got the bike and I love it so much so anything you can help me out with would be so nice!

So, pardon my ignorance but how do you adjust the rear shock? Do I need to take the weight off the rear to do it? Also, will this alter the ride height? ( meaning will it sit any higher overall with me off of it or will it sit the same but only firmer? ) Know what I mean?

If I'm not mistaken, you turn the screw on the lower side of the shock with a 10mm socket.. It goes from 1 to 5, and if you turn it too far, it just goes back to 1.

You do this with the bike just sitting (and you not on it). It's preload, so yeah, your ride height would be increased slightly.

suspension feels too soft

mr foxx,
My first question would be; how much do you weigh? You need more spring rate if you weigh more than 170#. Adding preload wont make up for too soft a spring rate.
The rear spring preload adjuster is a 12mm bolt looking thing on the left side of the shock near the top of the spring. Much easier to turn it tighter if the rear wheel is hanging topped out. (no weight sitting on the rear suspension)

The best solution to the rear feeling squishy is to improve the hydraulics thru a Racetech Goldvalve kit, or a better shock. That will do more to improve the ride than most folks can imagine.

Use the schrader valves on your forks to release any built-up pressure, don't add air. If you need the front end firmer use straight rate springs, lightly preloaded.
Again the hydraulics are best fixxed with a Goldvalve Cartridge Emulator kit.

We do professional installs of the racetech kits everyday. Done right with good choices on all the variables, this will produce a high quality upgrade to your KLR. The ride will blow you away.
You might think you are on a different bike.

I weigh 196lbs and the 1 setting on the shock is way too soft! When my girlfriend is on the back it's even worse. Thanks for all the info guys!!

Suspension feels too soft

Mr. FOXX, at 196# plus the girl friend, going to the #5 setting might help in a tiny way, but not like firmer springs will.
you will benefit massively from the proper spring RATEs , but not preload. Here's a few ideas on options and solutions for you.
First, you can do whatever, yourself, or;

second: I have a developed a KLR specific shock with Penske Racing Shocks. A 8900e series shock for the KLR, brand new, custom built, per application, 2 wks delivery time at $615.99.
This is for an emultion style shock with damping, spring preload and ride height adjustment,

Or third: I have a GMDATL spec Racetech Goldvalved oem unit that I will put the appropriate spring on for you all for the low low price of $435, exchange. That buys you the goldvalve kit, the spring, oil and labor. I could send that out to you immediatley. you send me your core shock.
I can also put a remote resevoir so you have a compression adjustment too, that will add some cost to it.
Either way I will offer satisfaction garaunteed.
If you are interested, you can call me at 706 253 1148

Wow thanks for the info! I don't think I'm ready to upgrade to a new suspension just yet but when I do I'll surely revisit this thread and what you posted! I was just hoping to firm up the suspension the easy way I guess. I have no doubt that what you have will do the job and then some. Heck, just the suspension tuning that I had done on my stock Honda 929RR made a huge difference! I couldn't imagine what a custom unit might provide! So, that being said, just by cranking it up to 5 won't really do me any good for taking the sag and squishyness out of the rear? Thanks!
