Bajaj’s Freedom 125, the world’s first CNG-powered motorcycle, features a 125cc engine that runs on either petrol or CNG. Despite its innovative design, the bike’s CNG tank is limited to just 2 kilograms, prompting questions about its size. Here’s why:

• Weight Constraints: The 2-kg CNG tank weighs up to 18kg when full, similar to a full petrol tank on a Pulsar.
• A larger tank would increase the bike’s weight significantly, affecting ride dynamics.
• Cost Considerations: The CNG system is expensive, and a larger tank would drive up costs, challenging the bike’s affordability under Rs 1 lakh.
• Pressure Limitations: Current CNG dispensing pressures (around 200 bar) limit the amount of fuel that can be stored.
• Bajaj suggests increasing pressures to improve tank capacity.

Future advancements may address these issues with lightweight materials and higher pressure systems.
