These shocks fit but with a bit of hassle.
The standard spring is too soft unless you're a featherweight 8 stone or less & don't think about a pillion! A re-spring is needed to be safe
Although some people have transplanted the Fazer FZS 1000's rear shock onto their 600 (and this is a step in the right direction), these R6 shocks are an improvement again as they have separate high & low speed compression adjusters (particularly useful for overcoming those jarring, sharp-edged bumps that litter our public roads)
Save yourself a lot of p1ssing around by REMOVING the suspension linkages to allow the shock to fit more easily! While they're out, give 'em a good greasing.
The model you're after (13S) is the same one that all the 1000 owners are after, as well as GS500 twin owners(!) (2008 onwards shocks, it must have the compression adjusters together, not separate). That means you'll have to watch ebay like a hawk or just buy one off a 1000 owner. Still, much cheaper than the likes of Nitron's basic emulsion shock & actually offers more adjustment options.
At 293mm long from eye centre to centre, its nearly 10mm shorter than the standard shock, so need different dogbones. I went with multiple height plates listed frequently on ebay that allow four different options & chose the highest ride height (normally +40mm) which is still slightly lower than standard.
Luke / Devilyam's suggested settings,
"Setting the high/low compression damping at 4 clicks out from full hard on the high speed adjusting nut, and 16 clicks out from full hard on the low speed compression blue screw worked well for me, and my weight. Rebound damping i have set at 16 clicks out from full hard, and that worked well, also."
