I own a Maestro from Last 3 year and it really keep up good no big issues. About the mileage its good. Now after 3 years and regular service I achieved 47 kmpl.
Its awesome. It has attractive carbon fibre textured seat which is really really soft an big enough for two seat and super comfortable.
Yet its tyres are are little slippery in moonsoon. You cannot keep speed in tight corners.
Hero Maestro is really awesome.
I loved the most is speedometer and digital odometer.
It gives perfect fuel reading and ofcourse service due indicator.
Its really really fantastic!
Loved it.
