For those considering fork spring changes, I have installed two sets of Race-Tech KLX 300 springs in KLX 250S bikes. They fit good when used with two preload spring washers in each side. There is 1/2" uncompressed difference in height when compared to the 250, but once installed with proper preload there are no problems. Install only took about 20-30 minutes per bike excluding distractions (two year old). I weigh 165 and used .42 kg springs andit feelsgreat now. Cost was $109 and free shipping from my dealer.

I'm sure Moto-Pro would have been just as good or better, but it was easier for me to order the Race-Tech springs from my dealer. I would've ordered from Moto-Pro if I could've done it online at the time.

 

Yeah, I'm all about who can give me immediate results once I'm ready to make my order. Thanks for the info. I'm sure there are a lot of people who will benefit.

I will eventually address the suspension, but because I weigh-inat 140lbs, it's not an immdediate need. My butt has the biggest vote right now, so I think a seat will be on order soon. The seatshould compliment the Clark 2.9gal tank nicely

 

I'm the other set of springs that Wes installed. Being a bit heavier at 185 pounds, I went with the .44 kg spring rate.

What a difference it makes! The gentle wallowing that the bike did at speed on dirt roads is gone. I can actually come up fast to a 90 degree corner on a dirt road and pitch it sideways and setup a nice powerslide coming out of the corner. Before, the front end would want to turn in too much or just kind of 'crab' through the corner. It felt like a highside waiting to happen.

Trail riding is better too. I don't feel like I'm going to bottom out on big ruts anymore and it's a lot less jarring through the handlebars. As long as you're doing your part with weight transfer, etc, the front will stick where you put it. (Assuming you have a good front tire for the dirt .)

It feels better on the pavement too. Fork dive is greatly reduced and the bike feels a lot more settled in fast sweepers. It's a lot more 'flickable' too. In quick left/right transitions, the forks don't pump anymore.

Thanks for the help Wes!

 

Thats probably next on my list of things that never gets smaller... better suspension.
