Whatr is the front spring rate?

I have stock fork springs from both 5th & 4th gen, and I'm curious to know what the spring rates are.

Thanks!

According to ractech:

3gen: .634 kg/mm
4gen: .701 kg/mm
5gen: .740 kg/mm

Cool, thanks Doug! It wouldn't be much, but the 5th gen springs could tighten things up a hair on the 4th gen, it seems? They should slot in as the forks are about the same length and diameter? Just thinkin out loud here, sitting on a pile of parts in the garage...
