CRF Springs

[Bent6]

What weight will stock CRF450R spings support with proper sag? I've been told 200lb, but that seems a little stiff for stock springs.

Thanks

The MX-Tech Spring Rate Generator says stock 02 CRF springs are good for 215lb motor cross. It does not list the 03's. Do 03's have the same rate springs as 02's?

Thanks

I think the 03s are stiffer.

03's are .47 same as 02. The rear spring went up in rate to 5.6
