What kind? I have a Ninja 650r and a Buell 1125R. Got a good deal on a Yamaha FZ6R. It's essentially a dumbed down 600... my dad and insurance price talked me out of the R6 I wanted (i'll probably have a better chance of living until i get comfortable on the bike lol) When you decide you want more performance you can just get a piggy back ECU for cheap (and if you want to, but not neccesary, R6 cams) and you can get alot more out of the bike. The FZR is just a detuned R6 03-05 engine. You may actually like the FZ6R more, it has better mid range torque though it lacks some high end so for highway/city cruising the FZR is a better choice. If youre going to track it, the R6 of the same year has the edge... newer R6's also have some extra goodies but nothing huge for a first bike. Let me know if you have any questions about the bike, especially the engine as I've designed and built Formula race cars using the same years R6. If you want some tips on things I'd change right away to save yourself a headache down the road let me know.
