I have a 2008 crf450r that I purchased new in 2009. I sent my suspension away to RG3 for revalve and springs in 2010. RG3 stayed with the stock 5.5kg/mm rear shock spring and went with .48kg/mm spring in the forks. There have been times when other riders commented I should be running a stiffer shock spring? Now, of course, I'm wondering if I should purchase one and try it out. The suspension, as is, seems to be working good. Should I stay with what I got or spend the money and purchase a stiffer rear spring? If yes, should I then consider stiffer fork springs? Any feedback/suggestions would be greatly appreciated.

Race sag: 101mm (with gear)
Static sag: 28mm
Weight: 195 lbs (with gear)
Height: 6'-1"
Type of Riding: MX Tracks
Ability: B Class Vet

Thanks in advance,
Rob

I would listen to your suspension tuner first.

It does seem like you are right on the edge for a stiffer shock spring.

Suspension has a lot of room for personal preference. If you like the way the bike feels, there is no wrong choice.

Thanks for the input Leardriver.
I talked to my local suspension guy and he seems to think a stiffer spring is worth trying. So, I ordered a 5.7. Looking forward to testing it out. Gonna be a while tho. Snow still on the ground up here in Canada. Once it warms up and I get a few rides in I'll let you know how the new spring works out.
