Unicorn 160 has fast pick-up when compare to unicorn 150 and has almost equal mileage The whell sizes are reduced so that its stability while driving reduced so when u do turns with Unicorn160 be cautious, It wont give as flexible turns as 150cc.Recentlly I fell down while turning at a corner. According to my view the design is not improved, Except design everything else is very good.One other factor which I need to mention here is shock absorption, which is not good . I think the designers much concentrated on slimming the bike but in that process they sacrificed some safety and flexible things which they gave with UNICORN 150,
