Honda unicorn is best bike in 150cc category , I am owner of a unicorn bike since 2013 and it is so reliable that never taken it to mechanic since I purchased this bike, if we talk about fuel efficiency then it will be about 45-50 km/liter, while riding this bike u will get a different experience grunted. Due to its suspension system up to speed of 90km/hr, but above the speed bike will start getting unbalance and u will feel some how distracted from path, setting arrangement of this bike is simple, another thing that will reduce its rating is that engine and silencer get extremely heated during continuous running. Over all this bike is value for money
