While we Indians worry too much on fuel economy and an Indian company is the world’s largest seller, the Argentinians have got ahead in this respect- Argentinian company Zanella has launched a CNG powered bike.
This is possibly the first bike in the world to come with a factory fitted Compressed Natural gas power.
The bike is essentially a converted RX-150 model and as the name suggests, displaces 150cc. The bike has space for two tanks that stocks enough gas for a range of approximately 100km (120miles).
The tanks store a total of 1.4 m3 of natural gas and the storage tank is in the same place as a conventional tank. Also on board is a 3.5 litres gasoline tank which will take care of immediate emergencies. The CNG option costs US$ 285 (1000 pesos) and is supplied by local manufacturer Ecopos, based in Santa Fe, Argentina.
