I bought a FZ6 S2 in Oct 07 after passing my test. So far I have only covered 600 miles (running in) and am still being precious about taking it out in the wet or on salted roads. I added the top box and carrier, heated grips (oxfords) and the taller touring screen - considering fairing lowers but haven't made up my mind yet. The bike was pre-reg by the dealer and I paid £4950 including the extras.
So far I have found it user friendly, comfortable, good fun and more that capable of out performing me. During the running in period I kept it below 6000 rpm for the first 400 miles. For the next 200 I stayed below a sustained 7000 rpm (advised in the handbook) but did allow the engine to spin upto 9000 rpm for 3rd or 4th gear overtakes.
I'm 6 foot and 17 stone. I've found the handling good (remember I am a complete novice) - added a click of preload to the rear suspension to cater for my weight and added 2 lb/in2 to the rear tyre and 1 lb/in2 to the front; sort of part way between the recommended pressures for a 90Kg rider and fully laden at 190Kg.
Fuel consumption has been around the 47 mpg mark.
I've just had the first service carried out (basically an oil and filter change) and a few adjustment to cables etc - cost £30.
Hope this helps
