The Bajaj Freedom 125 NG04 Drum is touted to be the first CNG powered motorcycle in the world and has a unique bi fuel system that allows it to run on both CNG and petrol. This innovative approach will reduce emissions, save cost, and yet it is a question of how practical it is to use a CNG motorcycle everyday. The limited number of CNG filling stations, long refueling time, and weight and handling problems caused by the CNG tank have been areas of concern. Furthermore, there have been some reports of power delivery problems when changing between fuel types. Even the debate is continued as to whether the potential fuel cost savings are worth the inconvenience and limitations of the CNG system in areas where CNG infrastructure isn’t well developed. Discussion has been generated on the real world practicality of CNG powered motorcycles as a sustainable alternative to conventional petrol bikes.
