Well, there's talk of the '08 model which I suspect will be hardly changed apart from maybe colours.
However, longer term I'd like the following:
* Bigger tank (fewer stops to fill up)
* Bigger radiator for better cooling (reduce fan coming on in traffic)
* Better front fender (so I don't need to buy an extenda)
* Temp gauge in display
* Gear indicator in display
* More space under seat
* Better headlight as stock (haven't done much riding in the dark but it does seem feeble)
* Slightly wider mirrors (to see more of what's behind me and less of my elbows)
These are minor niggles rather than major annoyances and I'm sure I'll find more as the miles rack up. However, these issues wouldn't stop me buying the bike again given the same circumstances.
