The FZS is impossible to beat with anything new of a similar size even the FZ6 doesn't cut it. Time and time again my customers wish they'd never sold theirs or end up getting another, there's just nothing out there. All the newer stuff has bit's that better the FZS, like ABS or emission standard to get you into to cities etc, but none can match what the FZS can do, size, power, performance, weight, comfort (2up), running and service costs it was pretty well right straight off the drawing board.
You need to look at the adventure type bikes, but to match the FZS power/performance you'll have to look at 1000's which will hike the insurance and they're mostly bigger bikes all round.
FZS is as mentioned is unbeatable, good luck mate.
