The people who say that the bike average is low, are wrong. I have this bike for 9 months and it has run 14000 km. My daily commute on an average is 70 km out of which 60 is on highway on which my average speed is 75 to 90, it gives me an average of 50 to 55 km/l.
I don’t know what problem lies in all yours bike mine is perfect.
Now for vibrations get a good tyre and check the pressure of air level of back tyre in your bike.
I have race with this bike with almost all 125 cc bikes and nobody is near about me. Well the initial speed is low but after 50 km/hr speed, it sails to 100 in no time.
Tyres are worst for high speed, and it might lead to accidents. So please change it before you get hurt.
Look is awesome and the rear suspension is super awesome with pillion.
