Its been one year I bought this bike, really well satisfied to ride. At first my bike mileage was 70 kmpl, after Hondas first free service it got reduced to 62 and they said to drive in 45 speed, which was irritating. Then I took my bike to local bike service point and mechanic to tune the mileage and now I get a whopping 87 kmpl when I go in 60- 70 speed. This was amazing. I suggest you not to take to Honda showroom and spoil the Bike. They are really useless.
The engine is 110cc, but all my friends who drove the bike said its not less than 150cc, the performance and power is all good depending on our gear shift and drive.
I wish I have a thick back tyre and one more gear shift could make the bike perfect. But overall its a very good choice on buying the bike at this budget.
