1)Mileage of bike is around 37-40kmpl in city if not ridden aggressively. And 40-45kmpl on highway.
2)Comfort for pillion is not that good, as the pillion seat is not that wider. But rider seat is so comfy.
3)Reliability is not much a problem as it is homegrown bike so parts are easily available. But refinement level of gear box is not up to the mark, and engine also jerks sometimes if revved too racy. Due to open chain on bike it attracts dirt a lot, so it has to be lubed and maintain all the time else performance suffers drastically.
4)The MRF tires plays a mind blowing role for grip. Although they are too small but still even in hard braking in slippery roads bike will not skid. Thanks to the wider rear tire. But rear breaks are of no use, and Avenger owners dont even bother to apply rear break, as it wont stop bike even slightly. But Front disk is outstanding, It has incredible stopping power.
5)It is eye catchy bike in India due to being only budget cruiser made by Indian manufacturer. Due to its low slung appearance it gives a chopper bike sort of a feel. And dark theme on 150cc variant makes it sometimes confuse between some international bikes.
