Hi Andy!
I just got one and they are great!!
Regarding tank range, I had my fuel warning light come on at 84 miles the other day. The good news is that this happens with about a third of the tank left. Once your fuel light goes on, you then get a 'fuel trip' display telling you how far you have travelled since the fuel warning light came on - rather than 'trip 1', 'trip 2', or the Odo. I suspect that my 84 miles was the result of me hooning away from the lights all the time...I can't help it!
Anyway, the MT03 is not the bike to buy as a practical tourer. It is however a very capable and fun streetbike that does not put your license at too much risk by exposing you to high BHP figures (my reason for getting one - I currently have 8 points). Low and mid-range torque is the way-of-the-walk here!
Regards
Tara
