$400/month....ok, well, yeah, that's more realistic. When you quoted that solo and then all the others in yearly I thought you were talking a full year for $400. That's possible for experienced riders on non sport bikes, but not for a new rider on a supersport.
Keep in mind that it may not seem bad at this point but when you're paying that $400/month still in October/November thru April when the bike is sitting unused, it may not seem to palatable anymore. Something other than a 600r for your first bike will likely get you into a better insurance segment. When I first started riding in the 90's I was paying in that territory then myself for my first bike and I remember thinking it was all great in the summer...but once winter came around and I watched that chunk of money leave my bank account every month even when I hadn't had the bike even uncovered for months, well, it sours things a little.
