I have been driving my Honda Unicorn since last 5 years. Till now I haven’t got any major problems with it. Definitely a great bike to drive in city as well as on highways.It is a little heavy bike which keeps it steady at high speeds but will affect you if you are driving through tight corners.Also the milege is great. I am getting about 52-55 km/lit. This bike literally delivers whatever you expect from it. Also it is very comfortable for long drives. I am used to of driving my bike for about 150km once or twice a month. Can reach a speed of about 90km/h very easily. There is a little problem after you cross 100kmph mark. The engine starts to vibrate a little but it is a minor issue. You won’t even feel it. About the servicing part. I did not had any problem related to the service centres. Also the servicing costs proved to be economical. I service my bike every 3 months and I’m always happy as it is worth it.So all in all Honda Unicorn 150 is a very great bike. Go for it.
