Question about spring rates on a YZ 250. (Racetech)

Recommended Posts

I have a 2000 Yz 250 with stock springs in it (as far as i know). I weigh 190lbs and I'm 6'1". I ride mainly MX tracks and usually jump everything, and can not stand bottoming out all the time. The stock springs are too soft for my weight, so i'm looking to upgrade along with getting racetech gold valves front and rear(i get a nice discount because i know a guy).

RaceTech's spring calculator specs 0.46kg/mm fork springs and a 5.0kg/mm rear spring for my weight. Does this sound right?

The reason I ask is because I was going through the Yz250 suspension setup database and noticed that a lot of riders around my weight are using MUCH stiffer rear springs, like 5.6kg/mm. Whats the deal?

Also, i plan on getting these springs for my current weight, but will probably lose a bit of weight soon as i get more fit, and will probably be faster. Do you think the stiffer springs will be fine, given my lighter weight but probably increased skill? From what i read, the faster you get, the stiffer the springs you'll want, and really the characteristics of the suspension is controlled by the valving anyway.

Thanks in advance.

.

do they have 4-strokes?

YZ 2-strokes have a different wheel/shock ratio, so they use lighter springs

(4.8 is stock for the 2000 YZ250).

you are slightly heavier than the average rider, so 5.0 sounds ok IMO.

best thing is to post your sag numbers...

and, springs do affect bottoming resistance, but valving is more important. also you can add fork oil. what do you run? 135mm is stock, you can go up until 80mm

Chances are the cartridge seals in the forks are also worn. Race Tech sells a repair kit for $30 to help reduce the fluid blowing past the worn cartridge seals which can make it overly soft even with the right spring rates and oil height.
