lucifah, no need to think so negative about falling - just get good protective gear - jackets, gloves then you will worry less...

wonder if aprillia still selling the rs 125 in malaysia...
i saw the naza the other day - looks ok - but fit and finish i dunno...it's hyosung rebadge i believe.
krr 150 is just nice for starting out (mine - the choke a bit emotional though)...
