Need spring rate advice for '03 KTM 450 EXC

Posted by: E-Ticket---------------------
I just picked up my new '03 KTM 450 EXC. And even though I'm still on break-in and not in full-flog mode ..... I love it!
Specs:
I am *currently* 6', 230 lbs (nekkid). But I am on a serious training program to get down to 220 by Feb. '04 and ~195 lbs by summer '04.
Ability: I am an experienced intermediate.
Riding areas/style:
80%: I typically ride deep-woods trails in the Pacific Northwest - which means slick, rocky, crawln'-type speeds
20%: Will definately do 3-4 high-speed Grand Prixs - such as Elsinore Grand Prix. Ride pretty fast, fairly aggressive.
10%: Love to *play* on mx/indoor arena courses a couple times a year. I do jump - but typically nothing more than a very small double or table-top. 3-5' of air.... 5-20' of distance. So nothing big.
Given that my weight is either:
a) going to stay at 230
b) go to ~200lbs (Most realistic weight range is 205-215 lbs. with gear...)
and I ride a wide variety of terrain/speeds.... sometimes fast, but more trail-pickin' with limited air...
what's best suggestion on front/rear springs?
Thanks! - E-Ticket

At your current weight you should run .46's up front and a PDS4 in back.

My edit button doesn't work.
If you get down to 200lbs you will need .44-.46's up front and a PDS3 in back.

Thanks, CP. That mirrors what I've been thinkin'....
I've currently got a PDS-3 on my 400MXC and it was *just* outside of the proper adjustment range. If I'm *truly* going to lose the weight - I should probably aim for the .44/3 combo as giving me the best range for 195-215.
I thought about putting the PDS-3 on my 450 EXC -- but until I match w/ a fork spring change - it wouldn't be a valid trial.
Thanks! - ET

Personally, I have found it much easier to change springs than go on a diet. Buy .50's Then you can eat what you want this holiday season.

Too true, Cannon! <grin> - ET

Thanks for all the advice guys! I have decided to go with the 44s/PDS-7 and lose my fat a**. <g>
See you at Elsinore GP next November! -- E-Ticket
