...Buell Blast? I found a 2003 Buell Blast at a good price with low miles. However, I am 6' 3" and I don't know if I am too big for this bike.

it has a pretty compact position. call the seller and ask if you can test drive it, or just see it in person.

You can get different seat heights for those, butyou are tall and pusing it on that bike.They take a fair amount of maintenance too, unless you enjoy working on them I would forget it.

They're a pretty good first bike, and a lot of the things you constantly have to fiddle with on other bikes (valves, chain oil, etc) have been replaced with maintenace-free items. However, be sure to get the tall seat (it has no "scallop" taken out of it) and you might also need to put on taller handlebars or bar risers to make it fit you. I'm about your height and can more or less fit on the tall seat version.
