In my opinion you picked a *great* first bike. I started on a '93 Katana junker (kinda heavy), and almost immediately followed it with a 2006 BMW R1200 GS. Simply put, the GS was beautiful, expensive as hell, and just a bit stressful to ride. I eventually realized that fighting 500 pounds of motorcycle was taking the fun out of things, and the BMW logo was burning massive holes in my wallet.
I have found the C5 to be light, forgiving, and a blast to ride. Oh, and parts are cheap.
Ride the crap out of it, keep the bolts tight, and love every second of it!!
