Just wanted to share another good experience. I am to re-doing the suspension for my SV 1000. I have a new GSXR rear shock, as mine has over 30,000 on it, and was going to put in some Sonics up front. I've rebuilt the forks twice, but figured I'd put in some better springs. Anyways, I wasn't sure about the spring rate given that I was adding the GSXR shock, which is a little stiffer than stock, so I emailed them to see what they recommend. They responded that the spring they would recommend is the same rate as the stock, so don't bother ordering one, just change the oil weight a little. It was really nice to deal with a company who was honest enough to pass up a sale because it wasn't really needed. They could have told me to buy them, and I would have. So cheers to them.

What is the stock spring rate? __kg/mm??

You should PM RichDesmond and thank him, he is the owner of Sonic Springs.

Apparently 95 kg/mm. The rate calculator was putting me right on the cusp of 90 to 95. I guess I'll pack on a couple pounds to make it a solid decision.

+1, he's a great guy. Hey Rich, you coming to the Spring rally?

Here are the STOCK fork spring rates:
1999 - 2001 SV650 have 0.706 kg/mm fork springs.
1999 - 2001 SV650S have 0.706 kg/mm fork springs.
2002 SV650 have 0.712 kg/mm fork springs.
2002 SV650S have 0.706 kg/mm fork springs.
2003 - 2008 SV650 have 0.712 kg/mm fork springs.
2003 - 2008 SV650S have 0.670 kg/mm fork springs.

So Moving up to a .95kg/mm Would be much stiffer than stock. Thats what I just did but went to race-techs

Umm, SV 1k. When I did my 650, I went with a 9.0 with an 04 GSXR rear and 15 weight oil, and it feels great.

Uh...UtahSV has a 1000 not a 650 .
