Im just selling my DNA, ive looked around for a 125 and a friend recommended this, but i want to know, is it any good, i would like a bike that cruses confortably at about a mid range speed (60/70) but has the speed when you need it,if you get me. handling is always a big point for me, and are they mechanically sound? are they prone to breaking down? also what price would i be looking at for a second hand 1? 1600 - 1700? thanx
