Just brought a K4 naked bandit 600 for an approx 20 mile commute into london. Had a GPX600R a couple of years ago (first bike) but haven´t ridden since. First impressions are that it´s a great first´big´ bike. Looks good, handles well enough and goes great - pretty cheap too, particularly now the 650 is out. I´ve read a lot about it being too heavy but I it seems fine to me. Having puncture problems at the moment but I guess I should watch where I´m riding.
