I'm currently looking to upgrade to a 600 sports bike after doing my restrictions on a FZR250. Money permitting I can only justify spending around $6000 and was looking at ZX6/GSX-R600 and CBR600F around the 96-99 age bracket. I am looking for the best handling bike. Are there any other bikes I should be looking at? Will these bigger bikes handle as well as my FZR250? Because they are newer will they handle better or because they are so much heavier they won't be as fast around corners?
