I am using a pulsar 135 since 5 years and yet it gives an fuel economy of about 65kmpl which is the best thing which you require in these days. although the bike is just 135cc it generates enough torque. But the main problem is the vibration of the engine is very much which degrades the ride quality. also the engine gets heated up very soon and thus increases the vibration. the seats are not that comfortable but it gets the work done.
