I recommended the Vulcan 500, but I have a Shadow Spirit. I guess it depends on how far you want to step up. The Shadow would take a little getting used to as it is heavier and larger than the GZ (I got used to it pretty quick without owning any previous bike). I get about 50 MPG, with about 90% of my riding time being highway speeds. The 745cc engine is smooth and I couldn't do a wheelie if I tried; it is nothing like a souped up sport bike. It can be a little difficult to maneuver in parking lots and other tight spaces. I find the saddle to be comfortable for about 2 hours, then I need to take a 10-15 minute break. A relaxed ride is the best description. But I hope you can find a good one for 3K total cost, unless you are considering title, registration, etc as separate costs.

Also my 2007 has shaft drive, so no chain.
