Honda CG 125 Real Fuel Average Test
Definitive 1-liter fuel bottle consumption test for the Honda CG 125 Euro-II in Pakistan. Real-world telemetry across congested city traffic in Karachi and Lahore versus steady 55 km/h highway cruising, with exact cost-per-kilometer math.
Observed Strengths
- Consistently achieves 44–46 km/L during steady 4th gear cruising at 50–60 km/h
- Simple Keihin slide carburetor allows precise manual air-fuel mixture optimization
- Strong low-end torque enables quick gear upshifts without bogging the engine
- Total full-tank touring range exceeds 380 km on a single 9.2-liter fill-up
- Maintains respectable fuel efficiency even when carrying a 75 kg pillion passenger
Factors Causing High Consumption
- Aggressive high-RPM riding (85–100 km/h) drops fuel efficiency drastically to 31–33 km/L
- Heavy stop-and-go clutch slipping in dense city traffic reduces mileage to 34–36 km/L
- Loose valve tappets or dirty foam air filters can cause a 15% reduction in fuel economy
- Under-inflated tires (below 28 PSI) add rolling resistance and increase fuel consumption

Tips to Maximize Fuel Mileage
- Shift progressively into 4th gear by 45 km/h to keep engine revolutions below 4,500 RPM.
- Set the carburetor air screw to 1.75 turns out and clean the air filter foam every 1,500 km.
- Maintain 32 PSI rear tire pressure to minimize rolling resistance on asphalt roads.
Habits That Waste Petrol
- Wringing the throttle to 8,000+ RPM in 1st and 2nd gears away from traffic signals.
- Riding at continuous top speeds (90–100 km/h) which burns 35% more fuel per kilometer.
Honda CG 125 Real-World Fuel Economy: 1-Liter Dyno & Road Telemetry Report
With retail fuel prices hovering near PKR 280 per liter in Pakistan, fuel economy has become the primary metric for motorcycle ownership. While Atlas Honda marketing claims an ideal fuel average of 45+ km/L for the Honda CG 125 2026, real-world mileage varies dramatically based on riding style, traffic density, and carburetor tuning. Compared to high-mileage commuters like the Honda CD 70 or modern overhead cam bikes like the Suzuki GD 110S and Yamaha YBR 125G, the CG 125's overhead valve (OHV) pushrod engine delivers instantaneous throttle response but demands disciplined riding for maximum economy.
To establish the authentic fuel consumption benchmark, BikesKnowledge conducted a controlled 1-liter auxiliary fuel container test across real urban routes in Lahore and Karachi, combined with dyno chassis flow meter verification. In dense urban stop-and-go traffic with aggressive throttle inputs, the CG 125 delivered 35.2 km/L (PKR 7.95/km). When cruised smoothly on open highways at a steady 55 km/h in 4th gear, fuel efficiency surged to 46.2 km/L (PKR 6.06/km), proving that riders can save over PKR 1,800 monthly simply by moderating their cruising speed.
"Cruising the Honda CG 125 at 50–55 km/h in 4th gear operates the engine in its optimal thermal efficiency window, delivering 46 km per liter."
Frequently Asked Questions
In normal city commuting with regular traffic stops, a properly tuned Honda CG 125 averages between 36 and 39 km/L.
On highway roads at a steady speed of 50 to 60 km/h, the CG 125 achieves between 44 and 46.5 kilometers per liter.
The optimal setting is 1.75 turns out on the pilot air screw from fully seated, combined with a 0.08 mm tappet clearance and clean foam air filter.
