Heavy motorcycles generally refer to motorcycles with an engine displacement of 400cc or above, which are allowed to travel on highways. The following are relevant regulations regarding highway restrictions: 1. Speed limit signs: Highway speed limit signs indicate that the maximum speed must not exceed 120 kilometers per hour. 2. Legal provisions: Article 67 of the Road Traffic Safety Law stipulates that pedestrians, non-motorized vehicles, tractors, wheeled special machinery vehicles, articulated buses, full-trailer trucks, and other motor vehicles with a design maximum speed of less than 70 kilometers per hour are not allowed to enter the highway.

I've been riding motorcycles for over 20 years and frequently take highways. This issue varies by region. In China, heavy motorcycles generally refer to those with an engine displacement exceeding 150cc, and they are allowed on highways but must comply with local regulations—such as wearing a helmet and adhering to speed limits of 80 to 100 km/h. Some provinces like Guizhou or Yunnan may completely prohibit motorcycles on highways, so it's essential to check local traffic rules in advance. In the U.S. or Europe, highway access is much more liberal; as long as the vehicle passes its annual inspection, it's good to go. If unsure, it's advisable to check the official website of the transportation department or use a navigation app, which will alert you to any road restrictions. Safety is paramount—always check tire pressure and the braking system before hitting the highway to avoid stability issues from crosswinds.

As a safety riding advocate, I emphasize the importance of caution when riding on highways. Heavy motorcycles are fast and have significant inertia, making them prone to crosswind interference, which can cause body sway. Adequate protective gear is essential: wear reflective vests and full-face helmets, keep speed below 80% of the limit, and maintain a safe distance. Legally, motorcycles with displacements over 400cc are allowed on highways in many countries, but it depends on the route—certain tunnels or bridge sections may be prohibited. Regular motorcycle maintenance is crucial; checking chain tension and lighting systems can reduce the risk of breakdowns. Avoid highways in bad weather, as rain and fog impair visibility and make roads slippery, increasing accident risks. Plan your route in advance and avoid nighttime riding.

I've ridden heavy motorcycles on long-distance trips, and the highway experience varies from person to person. Small-displacement bikes shouldn't go on highways, while heavy motorcycles with 500cc or above can legally ride in permitted areas. It's crucial to check local regulations: highways in Beijing and Shanghai may allow them, but some highways in Shandong prohibit them—always verify before riding. Ensure proper motorcycle maintenance before the trip: check engine oil level, brake fluid, and tire wear. Use anti-fog windshields, as bugs can easily scratch them at high speeds. Bring a phone and power bank in case of navigation issues during emergencies. Always obey speed limits—no reckless riding—safety comes first.

For motorcycle beginners, understand the basic rules before hitting the highway. Heavy motorcycles are allowed on highways in most areas, but must meet displacement standards—generally 250cc or above is permitted, with some regions in China imposing displacement or speed limits. Check vehicle documents: bring your vehicle license and insurance policy, and don’t forget to wear a helmet. Consider installing a dashcam to record road conditions and prevent lack of evidence in case of accidents. Adding a windshield is also recommended to reduce wind resistance fatigue. Riding in good weather is safer; avoid traveling during heavy rain. Practice high-speed riding skills before departure, such as controlling your center of gravity during turns and maintaining a safe following distance. Schedule regular comprehensive inspections at a repair shop.
