Motorcycles powered by fuel engines with a displacement exceeding 50cc are permitted on highways. Displacement requirements must be met: Any motorcycle powered by a fuel engine with a displacement exceeding 50cc (including 50cc) is classified as a motor vehicle, thus motorcycles with displacements over 50cc are allowed on highways. Regulations for motorcycles on highways: When riding on highways, the maximum speed for motorcycles must not exceed 80 km/h, and the minimum speed must not be below 60 km/h. Lane changes are prohibited on highways. Motorcycle riders must wear helmets, carrying passengers is forbidden, and riding must be done in the far-right lane.

This issue depends on several key points. To ride a motorcycle on the highway, it must have an engine displacement of at least 125cc - small scooters definitely don't qualify. Last year I rode my friend's 150cc street bike on the highway without any issues. However, regulations vary by province - places like Qinghai and Xinjiang have more lenient displacement requirements, while coastal areas may require 250cc or more. You also need to check if the design speed meets standards - the speedometer's maximum speed should be at least 70km/h to safely keep up with traffic. Additionally, the bike must be from a legitimate manufacturer, you need to wear a safety helmet and reflective vest, and the vehicle must have complete license plates with valid insurance. It's advisable to check the local highway administration's regulations before your trip to be safe.

Let's break it down into two parts. First, the vehicle requirement: it must be a two-wheeled motorcycle with an engine displacement of 125cc or above. Mopeds are prohibited from entering highways, which is a nationwide regulation. Second, there are significant regional differences. For example, Yunnan allows motorcycles above 150cc on highways, while Guizhou outright bans all motorcycles from highways. During my long-distance travels, I've found that cruisers with 250cc or more are the most suitable—they offer good stability and can maintain a speed of 100 km/h for extended periods. While 150cc motorcycles are legally allowed, they can struggle during overtaking. It's best to call the local highway service hotline before your trip to confirm, so you don't make a wasted journey.

Riding motorcycles on highways mainly depends on engine displacement and local regulations. The national standard requires a minimum of 125cc, and the exhaust noise must not exceed permissible limits. In practice, a 250cc adventure bike is most suitable with its large fuel tank and stable cruising. However, the most annoying part is the varying regulations across provinces. Zhejiang started allowing motorcycles on highways last year but requires riders to wear a dashcam, while Shanxi completely prohibits it. I once rode a 500cc adventure bike from Sichuan to Shaanxi and was turned back midway. It's advisable to check the Ministry of Transport's official website or call 12123 to inquire about regulations in each province along your route, especially paying attention to prohibition signs at highway entrances.
