Bajaj Freedom 125 CNG Bike: How To Keep CNG Tank Leak Proof
The CNG bike comes with two fuel tanks: a primary CNG fuel tank, placed under the seat and a secondary petrol tank, which can be used when the CNG runs out

The Bajaj Freedom 125 CNG bike was recently launched in India as the world’s first CNG bike. Prices of the bike start at Rs 95,000 and go up to Rs 1,10,00 (ex-showroom). The CNG bike is powered by a 125cc, air-cooled, single-cylinder engine, which works with both CNG and petrol fuels.
The Bajaj Freedom 125 comes with two fuel tanks: a 2kg primary CNG fuel tank, which is placed under the seat and a secondary 2-litre petrol tank, which can be used when the CNG runs out. However, with the CNG tank comes its maintenance essentials which are different from a normal petrol fuel tank.
On the Bajaj Freedom 125 CNG bike, you have to get the fuel tank inspection done every 2 years at the Bajaj service centres. This test involves checking the CNG tank for damage, corrosion, wear and tear, its pressure holding capacity, nozzle, potential leaks and other components of the bike associated with the CNG mechanism.
This test should be done by the owner at a regular interval of every 2 years and on priority as it is directly related to the CNG tank and the rider’s safety. If you don't get the test done on time and the validity is expired, then the CNG pump will straightaway refuse to fill CNG in your bike, because of the potential risks involved. For your perspective, every CNG car also requires a CNG tank inspection, but the interval for cars is every 3 years.

- Review after 8k kms usageBaja. Freedom bio is ideal for long commute as it is fuel efficient, low maintenance and economical friendly. Dual fuel adds flexibility although slightly less powered but sufficient for travel without pillion and not much heavy luggage. Ridden 8000 plus kms ok pure CNG, less than 200kms used on petrol, I can say ride on CNG is reliable as Bajaj has been on CNG vehicles like in Auto rickshaw from decades. As said earlier it is slightly less powered but enough for single person travel. I would recommend as the bike itself is easy to ride although it is 148 kg but feels very lightweight while riding. With a great mileage of 90 plus on cng and may be 60 plus on petrol ( coz ridden vert less on petrol)Read More4 4
