I have owned an 08 600rr for the past 2+ years. Ill try my best with this review and im sure most of it relates to other 600's including the 05 RR..

Engine:
-Ok as your already aware, these things are FAST.. 0-100 in approx 3 secs or thereabouts
-1st gear can pull in excess of 115km/h on the 08
-the RR's usually have a strong mid-range so this is a positive for daily usage
-at 100km on the freeway your probably sitting at around 4k/RPM in 6th gear (will double check next time I ride haha)


Seating:
- Probably not the most comfiest of bikes for daily usage, but is relatively comfortable for a supersport machine
- In my opinion, comfiest seating position of the 600's along with the GSX-R 600.. the R6's positioning was way to 'race mode' for everyday riding (this is again, objective)
- ass starts feeling sore after lenghty rides

Suspension:
- in all honesty, all the 600's supersport machines have awsome handling, you look where you want to go, and it goes !
- the sussy on my 08 is relatively firm, but is soft enough for daily usage
- a cheap but great mod is to go to a suspension specialist to get the suspension dialled in for your weight. Honestly makes a world of difference
- these bikes are really flickable and with the right rider, the right tyres and on the right track, can give 1000s a run for there money

Aesthetics:
- this is a matter of personal preference once again, but I think they look good

Running Costs:
- services usually set you back from Honda approx $200+
- service intervals every 6,000km
- ofcourse, services can be cheaper at other places
- I get around 300km out of a tank

Misc
- really easy to lose your licence on lol
- great popo magnet, superb chick magnet
- kinda exxy to repair if crashed specially coz of the fairings, so even a light fall can set you back 1k+ if you want a brand new lookin bike
- good tyres are a must to really bring the best out of the bike
- exhausts make them sound amazing

Hope this helps and feel free to ask any other Q's
