I'm not trying to equate you to a child prodigy racer or anything, but unless there is something horribly wrong with your bike, and/or you have t-Rex arms, you can probably handle the bike alright. The questions you have on the limitations of lean angle, etc can be answered by you... If you want to do it in a safe, controlled environment, track day is the way to go. Sure, you can do more street rides with fast guys and maybe spend some time in a parking lot... But the only way to get instructors watching your riding and proving feedback, and riding in a environment designed for safely riding like a numbnuts is the track. If you're interested, come along to the track days/racing section of the forum. Be prepared for just absolutely ludicrous amounts of homo eroticism. It's really just madcat, the rest of us actually don't talk about dongs all the time. Feel free to pm me or anyone else active in the td/race section for more info, but a read through of the section will tell you most of what you need to know.
