What is the fuel consumption of underbone motorcycles?

Currently, the mainstream underbone motorcycles in China are mostly 110CC displacement. More relevant information is as follows: 1. Fuel consumption: For underbone motorcycles, the fuel consumption of 100 and 110 models is basically similar, while 50 and 70 models are rare. Some so-called 48CC mopeds are actually labeled with smaller displacements than their actual size, which is not truly 48/50 displacement. Moreover, due to insufficient power from overly small displacements, under the same usage conditions, larger throttle openings or lower gears are required. Therefore, even with 50 or 70 underbone engines, they may not necessarily be significantly more fuel-efficient than 100 models, and the fuel consumption remains roughly the same. 2. Note: Currently, 100CC underbone motorcycles have an actual fuel consumption of about 1.6-1.8 liters per 100 kilometers, while 50 or 70 models may be slightly lower, generally only about 0.1-0.2 liters less per 100 kilometers. Over 1,000 kilometers, the difference would only be one or two liters of fuel, which is not of much practical significance.

I've been riding underbone motorcycles for several years, with fuel consumption generally ranging between 45 to 65 kilometers per liter, depending on the model and personal riding habits. My old Honda Cub once achieved up to 60 km/L because I always maintained it diligently, regularly changing the oil and checking tire pressure. Avoiding sudden acceleration and maintaining a steady speed helps save fuel. Smaller engines, like 100cc models, offer even better fuel efficiency, approaching 70 km/L. Long-distance riding with less wind resistance yields higher mileage, while city traffic can drop it to around 40 km/L. I recommend beginners choose newer models like Yamaha's, as their official fuel efficiency figures are quite impressive. A sudden drop in fuel economy might indicate a clogged air filter or aging spark plugs, which should be addressed promptly. In short, underbone motorcycles are fuel-efficient, but the key lies in proper maintenance.

Riding a underbone motorcycle to commute every day, the urban fuel consumption is about 40 to 50 kilometers per liter, and frequent stops in traffic jams consume even more fuel. On weekends, riding to the suburbs saves a lot, with the highest reaching 55 km/L. I found that riding at a constant speed, using brakes less, and avoiding overloading are the most effective, and maintaining proper tire pressure can also improve efficiency. Switching to lightweight aftermarket parts is better, as heavy racks can worsen fuel consumption. There are significant differences between models; my friend drives a new Suzuki Smash and easily achieves over 55 km/L. If the fuel consumption is unusually low, it might be due to driving habits or the need to check the fuel system. After commuting for a long time, I concluded: choose a small-engine bike and avoid peak hours.

I work as a mechanic and often encounter inquiries about the fuel consumption of underbone motorcycles. The normal range is 40-70 kilometers per liter, with influencing factors including engine displacement, spark plug wear, or a dirty air filter. Older bikes with poor maintenance often have fuel consumption below 45 km/L; new engines like the Honda Wave, when well-optimized, can exceed 60 km/L. It's recommended to change the engine oil and check the valves every 5,000 kilometers, and avoid using low-quality oil. Insufficient tire pressure or a loose chain can increase resistance and fuel consumption. Riders often report significant differences in fuel consumption, mostly due to improper maintenance. A sudden drop in fuel efficiency may indicate a sensor malfunction, so timely repairs are advised to avoid bigger issues.
