If you feel you have out grown your GS Id say jump to it right now, or when ever the finances will let you. I think you will grow into it a lot quicker than you think. I sarted out on a gsxr750 (100hp) then took a 4 year hiatus then picked up my TL1000(125hp), took it easy with the TL till i got comfortable then started giving her hell. I'm no knee dragger but i'd like to think i'm a above average rider. Like i said learn self control and respect the bike and you will be fine. My current 1400 is still a learning curve for me but ive only had her for half a season.
