Spring

Thought I would share this tidbit of info, hoping it helps someone. I am a 205lb rider, could not get my static sag/rider sag correct on my 2006 FE450e. I have a friend with many KTMs, many spares, got a PDS4-250 spring from him. It dialed my sags in correctly, and is a great improvement. My stock spring was an 80-250. The PDS4 is supposed to be a progressive spring ranging from 85-110. I am a typical 50+ rider with not much left in the knees, I sit more than I used to, I like this spring!

Stoveguy, the KTM suspension is very similar to a Bergs. You can find springs from KTMs that will fit your bike, both front and rear. For your weight you will need to find the correct springs, hopefully someone of a similar weight will have some feedback. May 06 Dirtrider has an interesting article on setting up a Honda 450 for a heavy rider, most in the article applies to you and your bike, as well. Springs are rated by weight/distance, kilograms (how many) required to move the spring one centimeter, or millimeter. Some are rated in pounds/inch. The main thing you need to be concerned with is getting your sag ratings in the ballpark. Your owners manual has a good description of this. You will definitely need heavier than stock springs for best results.
