Hi, I'm after a rear lock out shock for my '09 575, to replace the fox rp23. I think the DT Swiss XM180 (200mm - 7.875" eye to eye) will fit. Can anyone please confirm and/or give me advise? I know I should put a tape mesure to it but I'm away from my bike working atm and won't to order shock so I can climbe out of the valley as soon as I get home. Thanks Ben
