What helped me when I started riding was I focus on riding well, rather than riding agressive. Riding agressive is easy, anyone can pin the thorttle, yank the steering as fast and as hard as they can or ham fist the brakes to lock them up. Riding agressive without first riding well is usually just an accident waiting to happen.
Riding well have nothing to do with how much hp your bike has or how wide your rear tire is, otherwise anyone who owns an R1 will instantly became Rossi. It is a mind set on how to prepare yourself to effectively control the bike so it can do its job.
When you can, find the time and do a trackday and I guarantee it WILL make you a better street rider.
