Xtreme is quite a good bike. Quite refined engine. Good looks and impressive edges. Mileage is good. Average 45-50kmpl. less need of servicing. All round a good bike. Racing bike with a monstrous power! Graphics and colour options are just awesome. And available in many colours. Hero is reliable in the market. CBZ with Advanced tumble flow technology which means the engine makes zero noises. I give a 4 star for the performance.
