more seat time

body position (get off the bike/kiss the mirror), you will be surprised at what you can do on a bike with better body position, sportbikes have way more lean angle than what most of us are willing to learn (espcially on the streets).

you will also be surprised on how much speed you can scrub off with the front tire just by leaning a lil more,

always know the roads that you are going to haul butt down, if ya dont know the road than you shouldn't be going that fast

start looking on local forums for rides, there is one that has a Sunday ride just about every weekend, tag along, get use to taking the twisties and each time out try to improve on 1 or 2 things,

read up, twist of the wrist, twist of the wrist 2, and there are a few more

bring it to the track, things you can learn @ the track can intrun make you a better rider on the streets

btw, never try to apply more brake while lean'd, you dont have as much of a contact patch and would cause the front to lock up and wash out from under you
