i just sold my Hyosung gt650, as I'll be getting my full licence at the end of the month. i was much happier paying $6000 for a 2 year old bike then the same for one that is 10-15 years old, you can bye them with a restrictor fitted to make them Lerner legal, and if you want to keep it after you get your full licence you can just have the restriction removed. i never had had a problem with mine, was countable to ride, looked and sounded grate, and you didn't have to rev to 15000rpm to get it to move anywhere. if you go to there web site or just Google it, there's heaps of info out there.
ps; a big loud bike gets more attention, which makes it a lot easier for other motorists to see you
