get the F4. now the F4i is out, but go with whatever honda is your choice. yamahas are great, but honda has displayed nothing but good engineering and winning bikes. a cbr 600 f1 beats a vfr1000 interceptor. how´s that? don´t get suzuki, they suck. they are high maintenance and cost too much money to fix all the time. yamaha is awesome stuff and they got motorcycles to prove it, but they just can´t beat the engineering of the unique CBR600 F series.
