CNG Motorcycle Refueling & Safety Rules
Official statutory protocol for two-wheeler compressed natural gas refilling under PESO and MoRTH oversight.
Standard NGV1 Dispenser Nozzle
No custom adapter needed. The filler neck follows international NGV1 specifications, identical to automotive passenger cars. Any standard commercial dispenser connects directly.
Mandatory Rider Dismount
Under PESO regulations, the motorcycle ignition must be turned off, and the rider must dismount the bike before the station attendant connects the 200 BAR high-pressure filling hose.
3-Year PESO Hydro-Testing (Rule 35)
Just like cars, two-wheeler gas cylinders must be hydrostatically tested every 3 years at authorized testing stations to ensure structural integrity and receive a valid compliance plate.
Frequently Asked Questions About CNG Bikes
What is the real-world mileage of the Bajaj Freedom 125 CNG bike?
The Bajaj Freedom 125 is ARAI-certified at 102 km/kg on CNG. In real-world urban traffic, owners consistently report 95 km/kg in stop-and-go city riding and up to 105 km/kg on open highways. In petrol mode, it delivers approximately 65 km/l.
Can a CNG bike refill at normal automotive CNG pumps?
Yes. The Bajaj Freedom 125 features a factory-fitted standard NGV1 receptacle concealed under the front tank flap. It connects seamlessly to standard commercial dispensers across all Indian CNG stations without needing any third-party brass adapter.
What is the total driving range of Bajaj Freedom 125 on full tanks?
The combined total driving range is approximately 330 km: ~200 km on 2 kg of CNG plus ~130 km on the 2-liter auxiliary petrol tank.
What happens when the CNG tank runs empty while riding?
The rider can flip the handlebar switch seamlessly to switch between CNG and petrol on the fly without stopping the engine or cutting power. If CNG pressure drops below operating thresholds, the system switches to petrol smoothly.
Is the CNG cylinder under the motorcycle seat safe in a crash?
Yes. The cylinder is enclosed within a high-strength steel trellis perimeter frame that underwent 11 rigorous safety and collision tests under ARAI supervision, including a front impact test, rear collision, and a direct truck run-over load test.
Does a CNG motorcycle require PESO cylinder hydro-testing?
Yes. Under Gas Cylinders Rules (Rule 35) administered by PESO, all automotive natural gas cylinders in India, including motorcycle tanks, must undergo hydrostatic testing every 3 years at authorized test stations.
