I need a stiffer spring

[By jones422, Posted April 6, 2010]

I ride a KTM xc-f 450 and weigh 225. I checked with a company on the correct shock spring rate and they said to go with a 8.0 but i belive the stock spring is a 8.8 and it is too soft. Any recomendations?

I believe they misinformed you. You should be about a 10.7kg. Go to racetech.com and dial yourself in.

If it is an 08 450 XC-F and you are 225 in gear and ride HS use a PDS6 . You will be much happier with the progressive spring.
