IF I WAS YOU I WOULD GET SOMETHING BIGGER THAN A 600CC, BECAUSE HOW FAST YOU WANT TO GO IS UP TO YOU, NOT THE BIKE. I GOT A 600CC FOR MY FIRST BIKE AND I WAS READY FOR SOMETHING BIGGER WITHIN ONE SUMMER. I WENT FROM A GSXR600CC TO A CBR 900RR AND I LOVE MY 900RR. I WAS TOLD NOT TO GET IT BECAUSE IT IS HARD TO KEEP THE FRONT END DOWN. THIS IS NOT TRUE, I CAN KEEP IT DOWN IF I WANT TO.GOOD LUCK, JUST REMEMBER YOU ARE THE ONE WHO CONTROLS THE THROTTLE.
