I bought this bike 3 months back and rode more than 5000 kms. Please check complete review below.

Here is my experience with Unicorn.
1) There in no other vehicle in 150cc segment that looks this much dashing and matured. You just find it standing beside any other bike and they look very timid or chotta bhaiyya kind of.
2) Every weekend I go for long ride 130 km in single sitting and I never had any issue and never ever any two wheeler dared to overtake me. :)
3) These beast are really very silent. When on Delhi roads you will see pulsar/apache making so much noise to overtake, Unicorn overtake them silently and very smoothly like king.
