So I put in my sonic springs yesterday and noticed that the stock springs looked pretty hearty...

I have not owned this bike since new and Honestly for as big of a guy as I am I have never really had too many issues with the bike bottoming out, I will say that with the new springs the suspension feels 100% better and stiffer and does not dive much if at all lol, But I was wondering if these springs are stock or some lower weight aftermarket springs.

I don't know for sure, but they look short like stock springs.  Here is a comparison shot of stock (pre spanish-built?) and Progressive:

Here's a working picture.
They look stock.
2 versions of stock with their spacers on the bottom.
Sonic 0.85 on the top.
I have since discovered there is a 3rd stock spring in between the 2 shown here. I found it as I took apart a pile of forks to rebuild.

My Sonic Springs came with .85 hand etched in end of the spring to indicate the weight. Check the ends for an etching. My stock springs had no #'s.

Yeah mine look like the middle spring in that pic.

I thought that all stock springs looked like the bottom one. It seems these are half decent as far as compression goes. So I guess Suzuki slowly improved the fork springs.

didn't the later (04+) models get better or bigger sproings?

The middle one is 2004+.
Bottom is 1989-2002. and  I believe I found a 3rd factory spring in between those two. Though the parts lists do not show a 3rd spring part number.
Interesting - the old springs are listed as still available. The newer 2004+ springs are listed as discontinued. WTF?
Oh, the 3rd spring is listed in 2004-2006 NOT FOR US MARKET. I did get one set of springs from the UK in order to get the adjustable fork caps. So that's where the 3rd OEM spring type came from. And that spring is listed as still available.

adidas sell me your fork caps!!!! I <3 rare parts tooo!

Junior won't give them up for anything. He looks pretty good for a 1992.

Damn adidas, your bike is so much cleaner than mine. sigh.
