The biggest difference between Rallye and Adventure or Overland is the PDS addition for the Rallye. Position Damping System will basically ensure a bottoming free shock and will allow different settings compared to Adventure or Overland. Looking ace! Sorry for your loss! Been through that 7y. ago . Hard use means bottoming hence the PDS. You don't have to be Coma to bottom this heavy bike so if money is not an issue, I'll go with Rallye anytime no matter the riding style (unless one uses the 690 as a daily commuter on tarmac, but then you don't think the 690 OEM suspension sucks big time). To lower it a bit, you could get a new seat which although with reduced amount of foam will be much more comfortable than the stocker.
