Hi I have owned many motorcycles before harleys, suzuki rf 600, ninja zx7r,prostreet etc. I am really looking to buy another sportbike again the local market here has a few decent prospects, there is a 2001 gsxr 600 with 8 inch swingarm chromed everywhere custom paint etc only 7500 miles and clean title for only 2500, but i have really been wanting a 750 or liter bike my question is can a 600 be built to outperform the 1000 or 750 or should i just keep waiting for the big boy bike?
