Heh, apparently I didn't properly convey how cheap I am. I paid $400 for my last bike (91 ex500) and $2k for my 09 250r with crash damage. So i'd prefer to stay under $200 for a rear swap including the tire

I'd probably be doing the work over the winter so I have time to be patient and wait for the right deal, or just use the FZR600 suspension I have in the basement.

Thanks though.

Anybody know what the stock ninja spring rate is?

Stock ninja spring rate is 9.3 kg/mm according to racetech. They also spec out that the optimal spring rate for a 150 lb rider for racing is 8.4 kg/mm using their calculator thing. Maybe thats spec'd for their special damper valving.

Here are some OEM rear spring rates for reference (taken from racetech):
- 2009-up Ninja EX250: 9.3 kg/mm
- 2003-2004 GSXR 1000: 8.6 kg/mm
- 2005-2006 GSXR 1000: 8.1 kg/mm
- 2001-2003 GSXR 600: 8.0 kg/mm
- 2004-2005 GSXR 600: 7.2 kg/mm
- 2006-2009 GSXR 600: 9.4 kg/mm
- 2006-2007 ZX10R: 8.3 kg/mm
- 2008-2010 ZX10R: 9.1 kg/mm
- 2007-2010 ZX6R: 9.2 kg/mm

I didn't post others, because they were all much stiffer than these ones posted, and wasnt sure how well they would fit, especially with the external reservoir shape of some of them.

I measure:
stock: 320mm long
gsxr600: 317mm long

Install procedure:
- drill out shock on top and bottom. i used a 15/32" drill
- lower fork on the rear shock is narrower, so:
- make some clearance on lower swing-link thing. i used a harbor-freight milling machine. only need to file down a few mm
- same story on the steel pivot cylinder.
- bolt it up. dogbones hit the shock, so you'll need two longer bolts and a handful of spacers

because the shock is shorter, i'm going to make some shorter dogbones. stock dogbones measure about 165mm.

I made some new dogbones...came out to 154mm.

Sold my ninja. Got it back.

Re-did the wiring harness for track-only and put a tail on it...

This bike is fun!

I like the duck tape wrap hehe. Love the rs125 tail, it's one of the nicest looking tail fairings out there.

Why not just run a set of triple trees that pushes the forks out a bit farther forward and keep the bodywork?

That would mess up steering geometry and could quicken the steering ALOT.

I personally prefer the bobbed tail. Mean machine any way you slice it, though!
