Motorcycle emission standards can be found on the vehicle's compliance certificate. Emission Standards: The emission standards for China III motorcycles are GB14621-2011 and GB14622-2007, while China IV standards are GB14622-2016, which makes them easy to distinguish. Emission Standard Identification: Checking the electronic fuel injection system may not necessarily determine whether it's China III or China IV, as China III motorcycles also have electronic fuel injection. However, some China III models like those from Sanya still use carburetors instead of electronic fuel injection. Generally, both China IV and China III motorcycles have identification labels indicating their emission standards. Additionally, you can check the production date. Motorcycles produced after July 1, 2019, are China IV compliant. Some motorcycles produced shortly before this date might also be China IV compliant, as manufacturers started producing and releasing them to the market before the official implementation of China IV standards. Checking the frame number or frame plate is another method, though it's not highly accurate. The best way is to refer to the compliance certificate.

I also struggled with checking the emission standards when I last bought a new motorcycle. The sales guy taught me that the most straightforward way is to check the vehicle's compliance certificate or manual, which clearly indicates whether it's China IV or China V. There's also an environmental label on the vehicle, usually stuck on the lower right corner of the windshield or near the engine—just look for it. Online inquiries are convenient too; just enter the Vehicle Identification Number (VIN) on the official website or the environmental department's app, and you'll get the answer. Higher emission standards are better—they're more eco-friendly, fuel-efficient, and hold their value. Older motorcycles with lower standards might face traffic restrictions. My advice is to keep the documents safe after buying, check the exhaust during regular annual inspections to avoid trouble. Checking emission standards isn't hard; the key is not to slack off. Make it a habit to protect yourself and the environment.

After repairing motorcycles for ten years, I've found there's a knack to checking emission standards. Typically, the compliance certificate and body stickers specify the exact standard, such as China V or China VI. I often help owners scan the VIN code using professional apps, or they can enter the model on the official website. The level of emission standards affects the lifespan of the catalytic converter and fuel consumption—higher-standard vehicles are simpler to maintain. I advise owners to stay updated on policy changes, as some regions restrict low-emission vehicles. When buying a new vehicle, prioritize China VI standards. After checking, keep a record and don't lose the documents. For regular maintenance, always use genuine parts to prolong the health of the emission system.

Before buying a car, I care about the emission standards. When checking out a car, the salesperson directly showed me the compliance certificate, clearly indicating which national standard it meets. Online platforms like Xianyu or official websites also display emission details when searching for specific models. Choosing a motorcycle with higher emission standards has many benefits, being more environmentally friendly and holding better resale value. Verification is simple and doesn’t take much time—don’t overlook this. For new cars, it’s better to choose those meeting National V or above to avoid restrictions on older vehicles. In short, verifying emissions is a basic step in car buying, ensuring peace of mind on the road.
