I'm digging the floral cushion design...batik?

I was looking at the spring diameter on the Racetech web site for the 06-10 GSXR 600/750 and it looked like they are different.I think we also need to take into account the length of the springs as well, and not just the rates.
2012 GSX -R 600 has a 195mm spring length, but the 2003 GSX-R 600 has a 210mm spring length, according to the replacement springs by K-tech.
2005 GSX-R 1000 appears to have a spring length of 195mm also even though the eye to eye is different.
I went ahead and matched up the lengths with what you posted, I also find it interesting for example that the GSXR 1000 spring lengths all stayed the same except 07 and 08 which shortened by 10mm then went back to 195mm....
Looks like for these 600 shocks we need to stick with the 195mm length spring.
Also looks like the 600 and 750 springs, 06 and up would work as they are the right length.
The 1000, anything but 07-08 would work.
98-00 GSX-R 600 = 210mm
01-03 GSX-R 600 = 210mm
04-05 GSX-R 600 = 210mm
06-09 GSX-R 600 = 195mm
11-13 GSX-R 600 = 195mm
14-19 GSX-R 600 = 195mm
00-03 GSX-R 750 = 210mm
04-05 GSX-R 750 = 210mm
06-07 GSX-R 750 = 195mm
08-10 GSX-R 750 = 195mm
11-19 GSX-R 750 = 195mm
01-02 GSX-R 1000 = 195mm
03-04 GSX-R 1000 = 195mm
05-06 GSX-R 1000 = 195mm
07-08 GSX-R 1000 = 185mm
09-16 GSX-R 1000 = 195mm

See the screen shots, here are the links:
For both GSXR model series RaceTech require adapters which is what made me think they might be different diameters, the adapters might compensate for length also. Look on the screen shot for the line "Adapter Collars" the required adapters have numbers that might be dimensions for adapting length or diameter or both.Cool thanks, that helps our cause...........not sure how I missed that when I looked
So they are saying 178mm from Racetech, so I wonder who is right........
Let me measure my extra GSX-R shock and see what stock is...try to get the collars all the way out.....
This shock is off a 2016 GSX-R 600....I checked Race Tech who says 11-15 is the same.
I took the collars all the way out, the top collar I removed all the way, the one holding the spring, or compressing it, I took it all the way to the point I could easily rotate the spring on the shock itself by hand.
I measured twice with a digital caliper, once from the top to the bottom and the other way bottom to top from the flat sides of each end that rests on the collars, I measured:
191.94 mm and 191.42 mm
To me, that says the 195mm looks closer than 178mm, which I am not saying the 178mm will not work, but you might have to move those collars a ways down to get it preloaded good......
I think the earlier GSX-R's at 210mm will be too long to thread the collars without compressing the spring first with some spring compressors, then the thing will always be preloaded pretty darn good
Yeah I also notice they call it "Intall" yourself, lolFor both GSXR model series RaceTech require adapters which is what made me think they might be different diameters, the adapters might compensate for length also. Look on the screen shot for the line "Adapter Collars" the required adapters have numbers that might be dimensions for adapting length or diameter or both.
Keep in mind that the free length of the spring doesn't really matter, as long as the preloaded length is within the operating range of the shock you're putting it on. The PreGen 250's stiffer spring is about 1/2" shorter than the 500's, but it'll still just barely reach with the preload adjusted to match the weight of a rider who should be using that spring rate
But as long as your desired preloaded length falls somewhere in the normal range of the shock's preload adjuster, it'll work just fine. I've spent like 5 minutes total looking at my new GSXR shock, but even the 15mm difference between certain years might not be an issue. The 25mm between the shortest and longest is probably pushing it. If the spring is too short, you won't be able to secure it on the shock; if it's too long, you won't be able to get it on the shock at all, or without preloading it way too much.
Racetechs are perfectly fine, especially with their collars or spacers. I would also say the K-Techs are fine.I think the earlier GSX-R's at 210mm will be too long to thread the collars without compressing the spring first with some spring compressors, then the thing will always be preloaded pretty darn good
