Hey Slick, welcome.
I want to echo the 'starter bike' comments.
I'm 6'2" and 255 right now (trying to get back to 225!) and I'll tell you that you do not need a liter Honda or GSXR 750 to start on because of your size.
My wimpy 75-80ish horsepower 600R is about all I want to try to handle, and I had ~7500mi of experience on cruisers. An SV 650 would have been a perfect starter bike for me, but I found the 600R first.
Me at 255lbs, can get my bike to ~145 indicated. My buddy at 175 could only get it to ~152 indicated. Neither of these reflect true top indicated speeds of the bike, since I start to get nervous and won't go faster. Trust me, your size won't matter that much.
