Bajaj Freedom 125: CNG Dyno, Crash Test Safety Audit & 102 km/kg Telemetry
As petrol prices continue to pressure daily commuters, Bajaj Auto has delivered a historic transportation innovation: the Freedom 125, the world's first mass-production CNG motorcycle. Read our long-term endurance report in the Freedom 125 15,000 km maintenance review, review the operational breakdown in our Freedom 125 real-world mileage cost test, and analyze the Petrol vs CNG vs Electric 5-year total cost of ownership.
1. 124.58cc Dual-Fuel Engine & 102 km/kg Mileage Telemetry
The Freedom 125 is powered by a specially engineered 124.58cc air-cooled engine with a 10.5:1 compression ratio optimized for CNG combustion. Delivering 9.5 PS at 8,000 RPM and 9.7 Nm of torque at 5,000 RPM, the motor achieves a verified 102 km/kg fuel economy on CNG. Combined with the 2.0-liter petrol tank, the bike travels over 330 km before needing a fill-up. Compare its running economy against sporty 125cc petrol rivals in our Bajaj Pulsar N125 review, the TVS Raider 125 review, and our Xtreme 125R vs Raider 125 shootout.
2. Trellis Cage Structural Engineering & 11 Crash Tests
Safety was the central engineering challenge of mounting a 200-bar CNG cylinder on a two-wheeler. Bajaj designed an external steel trellis frame that cradles the tank beneath the seat, isolated from frontal, lateral, and rear impacts. The model passed 11 extreme crash trials without gas leakage. For traditional 100cc-110cc commuter comparisons, review the Hero Splendor Plus XTEC review, the Honda Shine 100 review, and our technical guide on carburetor tuning for fuel average.
3. Ergonomics, Pricing & EV Alternatives
Starting at ₹95,000 for the base Drum variant up to ₹1,10,000 for the Disc LED model, the Freedom 125 competes directly against mainstream petrol commuters while slashing monthly running costs. For mild-hybrid and electric commuter comparisons, see the TVS Jupiter 110 iGO Assist review, the electric Bajaj Chetak Blue 3202 review, the upcoming Simple Wave EV review, the family-focused Ather Konarc EL review, and flagship performance models like the Bajaj Pulsar NS400Z review.
