What is the minimum engine displacement for motorcycles to access highways?
3 Answers
Motorcycles with an engine displacement above 50cc are permitted on highways. Below are specific daily maintenance methods for motorcycles: Idle speed control: During the break-in period, maintain motorcycle idle speed at 100 rpm. Gear-speed correspondence: Ensure proper gear selection matches the riding speed. Braking technique: When braking is required, release the throttle, apply the rear brake with your right foot, while gently applying the front brake with your right hand. Spark plug installation: Hand-tighten new spark plugs until snug, then use a spark plug socket to tighten an additional 1/4 to 1/2 turn.
As a motorcycle enthusiast who rides on highways all year round, I must say that in China, the displacement requirement for motorcycles on highways is above 50cc. This regulation is not just a numbers game but a safety consideration. Engines that are too small, such as those below 50cc, lack sufficient power, leading to slow acceleration, difficulty climbing slopes on highways, and potentially causing traffic congestion or accidents. I remember once trying to ride a friend's 40cc small motorcycle on the highway, but the power was insufficient, and I was left behind by the traffic, which was very dangerous. Policies vary slightly by province; places like Guangdong and Zhejiang generally allow motorcycles above 50cc, while Beijing and Shanghai may have stricter or temporary controls. Regardless of displacement, safety gear must be complete: a securely fastened helmet, reflective clothing, and speed controlled within 80km/h. When choosing a motorcycle, it's advisable to opt for 250cc or above for a balance between power and fuel efficiency. In short, follow the rules, ride safely, and don't take risks.
I've been riding motorcycles for long-distance trips for several years and am very familiar with highway regulations. Domestically, engines above 50cc are required for highway access, but in practice, I recommend starting with at least 150cc. Engine size directly impacts the riding experience—too small of an engine means weak power and instability at high speeds. My 250cc street bike handles highways smoothly with quick throttle response and easy speed control. Safety is non-negotiable: a helmet is mandatory, along with protective gloves and knee guards to ensure visibility. Regional differences can be significant, so check navigation apps for route restrictions before traveling—for example, mountainous areas in Yunnan may have additional limitations. Regular motorcycle maintenance is also crucial, including checking tire pressure and the braking system to avoid sudden breakdowns. In short, safety comes first, choose your bike wisely, and don’t let a small engine ruin your trip.
