Riders across Pakistan are facing the pinch of soaring petrol prices, and many daily commuters are searching for practical ways to improve bike mileage. For owners of the Honda CG 125, one of the country’s most popular motorcycles, careful maintenance and proper riding practices can make a significant difference in fuel efficiency.
The Honda CG 125 has been Pakistan’s top-selling bike for decades, trusted for its resale value, iconic exhaust note, and low upkeep. According to the Pakistan Automotive Manufacturers Association (PAMA), Atlas Honda sold 90,483 units in August 2024 alone. This shows how deeply models like the CD 70 and CG 125 are woven into the everyday commute of millions.
Yet, despite its popularity, many riders report declining mileage averages, which are often traced back to simple maintenance oversights such as clogged air filters, improper lubrication, or under-inflated tyres. Mechanics say that resolving these issues on time not only restores the CG 125’s performance but also keeps petrol bills under control on crowded urban roads and rural highways.
Carburetor and Air Filter Maintenance
The carburetor is the heart of the engine’s fuel delivery system, regulating the air-fuel mixture. When the carburetor interior turns blackened with deposits, it signals inefficient combustion and increased fuel use.
However, experts advise checking the air filter before tampering with the carburetor. A clogged filter restricts airflow, which causes sluggish pickup, stalling, and poor fuel economy.
Honda recommends replacing the air filter every 1,500 km or during routine tuning. Riders should ensure they purchase genuine CG 125 parts from trusted shops, since counterfeit filters wear out quickly and compromise mileage.
Engine Oil and Spark Plugs
Clean engine oil reduces friction between moving parts, stabilizes engine temperature, and prolongs the bike’s life.
- Oil should be changed every 1,000–1,500 km.
- Popular choices for CG 125 riders include:
- Liqui Moly Street 4T 10W-40
- ZIC M5 20W-40
- Havoline 4T SAE 20W-40
These lubricants provide semi-synthetic protection, making them ideal for Pakistan’s hot weather and heavy traffic conditions.
Similarly, spark plugs play a vital role in mileage. Worn-out plugs cause weak ignition, incomplete combustion, and higher fuel use.
Mechanics recommend:
- Replacing spark plugs every 10,000 km
- Reliable options: NGK G-Power or Denso plugs
- Fouled plugs can be cleaned using petrol or carb cleaner
Restoring ignition with new or cleaned plugs can bring noticeable gains in mileage.
Tyre Pressure and Routine Service
Tyres directly impact fuel economy. Under-inflated tyres increase rolling resistance, forcing the engine to consume more petrol.
-For solo riding: 25 PSI (front), 29 PSI (rear)
-With a passenger: 25 PSI (front), 40 PSI (rear)
In addition to tyre checks, riders should ensure:
- Proper chain adjustment
- Regular tuning intervals
- Timely oil and filter replacements
With consistent service, a Honda CG 125 engine can easily cross 80,000 km while maintaining efficiency — making it a reliable workhorse for daily riders across Pakistan.
Honda CG 125 vs Competitors
The CG 125 dominates the market, but riders often compare it with Yamaha YBR 125 and Chinese bikes.
Here’s a quick comparison:
Mileage & Maintenance Comparison
| Motorcycle | Average Mileage (km/l) | Maintenance Cost | Strengths | Weaknesses |
|---|---|---|---|---|
| Honda CG 125 | 35–40 | Low | Strong resale, reliable engine, easy parts availability | Vibrations at higher speeds |
| Yamaha YBR 125 | 38–45 | High | Smoother ride, modern design, better suspension | Expensive parts, weaker resale |
| Chinese 125cc bikes | 30–35 | Very Low | Affordable upfront cost | Poor durability, low resale, inconsistent mileage |
Final Word
The Honda CG 125 remains a staple on Pakistan’s roads because it strikes the right balance between performance, affordability, and durability. While rising fuel costs are straining commuters, riders can still achieve optimal mileage by focusing on carburetor tuning, clean filters, quality oil, spark plug care, and tyre pressure.
Competitors may offer modern styling or cheaper upfront prices, but the CG 125’s proven track record makes it the go-to motorcycle for everyday Pakistanis. With regular upkeep, it will continue to deliver both its iconic growl and wallet-friendly mileage for years to come.
