300mm
29.5mm
38.8mm
24 coil, 7 tight, 17 open

calculates out at around 0.47kg/mm, but once the closed section is compressed there's 7 coils less so it's around 0.67.  from my notes on the 09 model I replaced springs on.

Thanks very much brad!!  [thumbsup] I just replaced the rear Sachs with an Ohlins unit, and am looking at replacing the front springs with linear rate ones for track duty.
