How fast can a domestic twin-cylinder 400cc motorcycle go?
2 Answers
Domestic motorcycles with a 400cc displacement can reach a maximum speed of 190 kilometers per hour. Here is some relevant information: Heavy motorcycles: Heavy motorcycles generally refer to motorcycles with an engine displacement of over 400cc. They are powered by gasoline engines and are two-wheeled or three-wheeled vehicles steered by handlebars. They are lightweight, flexible, and fast, widely used for patrols, passenger and cargo transportation, and also serve as sports equipment. Classification of motorcycles: Power-assisted vehicles (below 50cc), small-displacement motorcycles (50cc to 250cc), mid-range (400cc to 750cc), and large-displacement (above 600cc) are all referred to as large-displacement motorcycles. In China, motorcycles with a displacement exceeding 400cc are generally called heavy motorcycles.
I've ridden quite a few domestic 400cc twin-cylinder motorcycles, with speeds typically ranging from 140 to 150 kilometers per hour. For example, the CFMoto NK400 can easily reach 145 km/h at full throttle on the highway, but due to wind resistance and rider weight, the top speed might drop to around 130. The twin-cylinder design ensures smooth power delivery, unlike the noticeable vibrations of a single-cylinder, making daily commutes at 80-100 km/h effortless. With aftermarket exhausts or lightweight modifications, it might occasionally hit 160 km/h, but safety always comes first. Regular maintenance of the chain and engine oil is recommended to keep the engine in top condition. Lighter models accelerate faster but may compromise stability at high speeds, so don't always chase the top speed.
