What is the fuel consumption of a 400cc engine?

It depends on the specific model. Generally, it is around 3.8 liters or more. Displacement: Displacement (Swept-volume), a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. The working volume of the piston moving from the top dead center to the bottom dead center in the engine is called the cylinder displacement. If there are multiple cylinders in the engine, the sum of the working volumes of all cylinders is called the engine displacement. Classification: According to the standards in Mainland China, it is divided into: micro cars (displacement below 1L), compact cars (displacement between 1.0-1.6L), mid-size cars (displacement between 1.6-2.5L), executive cars (displacement between 2.5-4.0L), and luxury cars (displacement above 4L).
I've been commuting on a 400cc motorcycle for several years. Bikes of this displacement typically consume 3.5 to 6 liters per 100 kilometers. Street models like the Honda CB400 average around 4.5L, while sportbikes like the Kawasaki Ninja 400 can exceed 5L. Surprisingly, cruisers are more fuel-efficient. Last week I tested my bike - it consumed 5.3L during rush hour city riding, but only 4.2L on weekend mountain roads. Proper tire pressure can save 0.5L, while an overly tight chain might increase consumption by 0.3L. I pay special attention to air filter maintenance during servicing and always use full synthetic oil - after six years, my bike now consumes 0.2L less than when it was new. For new 400cc bike owners, installing a phone mount to monitor fuel consumption provides the most intuitive feedback.
There's no standard answer for the fuel consumption of a 400cc motorcycle. I often take friends on motorcycle trips and found that riding with a passenger increases fuel consumption by about 8% compared to solo riding. The difference between road types is significant – frequent stop-and-go in urban areas can push consumption beyond 6L/100km, while maintaining steady speeds on highways can keep it under 4L/100km. Modifications also have considerable impact; a friend who installed a racing exhaust saw his fuel consumption increase by 1L/100km, while I've kept my bike stock. Seasonal variations are noticeable too – cold starts in winter increase consumption by 5%, while summer riding proves more economical. My advice: choose your bike based on usage – touring models are more fuel-efficient for long distances, while street bikes suffice for daily commutes. Recording fuel fills and mileage two or three times will help you understand your bike's fuel consumption patterns.
