Recommended Posts

Would anyone want to swap an 04 CRF450R stock fork springs for a much softer springs for a 140lbs guy? I need softer springs.

Are you sure those will work with the 04 450 forks?

Can someone confirm this?

I have some .43s or .44s that I will trade for stock 04 springs. Both sets are stock honda from 00 and 01 CR250s. I couldn't use them because I am not a light guy.

This is what I got from MX-Tech:

It seems like it's a perfect match. Also, I can use a stock rear shock on the 04 CRF250R and put it on my 450 too.

Yes, they work, I can confirm it. I am running 03 CRF450 springs in my 01 CR250, front and back. I got those from a 150lb guy who put my 01 CR springs on his 450.

They are all interchangeable from 2000-2004 without a doubt.

Looks like the .43s are the closest but still not .41. Let me know.

James if you have an interest in buying '04 springs - let me know. I have a stock .47 set with 10-12 hours on them.
