Is there any CNG bike in India?

Niks, your link does not appear to lead to any obvious information on a CNG-fueled motorcycle. The Bajaj site itself doesn't offer any clues either. I doubt whether a CNG-fueled bike would be practicable. You need a pressure vessel for the fuel tank, which has to be a cylinder, so in order to make it look aesthetically pleasing it would have to be covered by something. On most Indian motorcycles (which by world standards are all quite small) there is not enough space around the carburettor to fit the mixing device needed in order to make the carburettor handle the CNG and mix it with air for combustion inside the cylinder. Of course, it's not impossible; here in New Zealand there was a big CNG conversion industry in the 1980s, but all on cars, but the technology would be convertable to motorcycles. It's just that I haven't heard of anyone doing it.

EDIT Okay, looks like I was wrong about CNG motorcycles (see link below) - but I doubt they are available in India

Yes very much.

Bajaj Platina has the CNG model.

its 100 CC bike and launched in 2008, over all response of this bike is good.

Also there is CNG/LPG kits available in market, if you are looking for conversion.Please refer to the dealer on the same.

no there are no CNG bike model in india it is not possible to have in india or wait for future they are likely to come in our country

bajaj was planning to launch platina with cng kit

you need to scroll down to the flag of India and ask there...you'll get more answers than you will here in the US.
