My wife had one as she was concerned about something heavier, having dropped the CB500 she was riding. TBH I spent more time on that than I did my KTM Duke, especially through the autumn and spring riding seasons. Indestructible engine, same small frame as the 125cc version I think, would never get less than 90mpg and the bike I've had the throttle wide open on more than the rest combined. Certainly had to plan your overtakes but there's something about ragging a slow bike fast than the other way around. They're pretty rare in the UK - a dealer came down from Kent to Devon to pick mine up and I was happy with the price he paid for it
