Here's a good thread; couple folks riding 2-up on a Ninjette in places that many will never take their dual sport. Pretty cool!
My first and current bike is a Ninja 500. Like you, I use mine for commuting and touring - an awesome first bike (especially for a 5'3" shortarse like me). Someday when I'm rich instead of pretty I'll have an F700GS or maybe an R1200R, but the Ninja will serve me well until then.
