I purchased my Hunk On jan 29, 2008 after a waiting of 2 months..Till now I have covered 27, 000 KM. with an average of 1000 km/month. Still its as new as it was in 2008. I am college student and went home on every weekend. 140 km every weekend. And I feel no tiredness during journey. Within this more than 2 year span, my bike got punctured 3 times-bike service was regular-and spent nothing for the maintenance....
Frankly, I have never measured the mileage, as its not the concern for me.weather it give me less or more, it cant stop me to travel on this bike. It gives me mileage around 34-40.
