Swiss army knife is the GS by definition. Does everything well but master of none. That isn't a discredit as I'm on my third GS (1988 bumblebee R100GS, 1996 R1100GS, and now my 2005 R1200GS). The only problem on the standard GS, and mostly addressed on the GSA, is the buffeting around the head.
When BMW added the small winglet fairings, it made all the difference. It is a do all bike but will overlap 0% with an S1000RR. Oh, and by the way, they hold their value amazingly. Bought it for around $13k in 2004 and a 2005 sells used today with low mileage for $8-9k.
I might pick up a KLR 650 way cheaper 300 mi range and more of a off road fun but just not as smooth on road . can be had dirt cheap and are bulletproof .
You know I looked at that guy too. The Kawi dealer wanted to sell me a new 2011 for $5,500 US. That may be an option...but my specialized bicycle costs 9K so I'm having trouble wrapping my head around the quality question if its so cheap.
My first bike was a KLR650. I spent about 50% of the new bike cost to farkle it into what I wanted. (Upgraded brakes, suspension, seat, bags, guards, exhaust, etc.) The newer KLR's are more road focused than the older ones (I had a 2006). It's a decent bike for the money but not sure I'd compare it to a GSA.
Honestly if I could only have 2 bikes I'd think a S1kRR and a GSA would be a pretty good pairing (at least that's what I tell myself!)
