My GSX1400

Cheers all, sorry I've been off the forum for a while! The swinging arm as said stiffens up the frame and reduces that wollowy feel as some people mention. I can't personally give any input as the bike was as is when I bought it and so far I'm very pleased with it, it's beast!

As far as I know, they stiffen the back end up (if it needs it) & helps overcome the 'wallowy' feeling you can get going round corners & through the twisties whilst heavily loaded (2 up or lots of travel gear).   Bit of expensive bling I reckon, aaannndd, lower ground clearance - no good for us Mike!

Stoli has one, maybe he'll read this & fire his experience in.

Yes yes Kiwi..  i have one on mine...  as i like to be stiffened up, especially as I'm considered a "2 up" - in that being a bit rotund i may as well have as much bracing as possible !!! 
as far as i know you have your existing Swing Arm braced.  Mechamex will do it for you i think.  mine was already on but i suppose a good ole Google will bring info !!!
