2021 Motorcycle Annual Inspection Regulations: Motorcycles within 4 years of registration must be inspected every 2 years; those reaching or exceeding 4 years must be inspected annually. For motor vehicles that meet the national safety technical standards, apply for the motor vehicle inspection compliance mark at the designated inspection site. The following circumstances will result in refusal to issue the motor vehicle inspection compliance mark: 1. Inconsistent information: Discrepancies in the recorded content of the motor vehicle license plate number, driving license, compulsory traffic accident liability insurance certificate, vehicle and vessel tax payment or tax exemption certificate, and motor vehicle safety technical inspection compliance certificate; 2. Unresolved violations: The motor vehicle has unresolved road traffic safety violations or accidents; 3. Unregistered: The motor vehicle is not registered locally and lacks an inspection authorization letter from the registration location's public security authority.

As a frequent motorcycle rider, I know that new motorcycles meeting China III emission standards couldn't be registered in 2021 at all. Since 2019, the country has mandatorily implemented China IV emission standards, requiring all new vehicles to comply before hitting the road. I remember back then the market completely phased out China III models, with DMVs directly rejecting vehicles with outdated emission standards. Cities were even stricter - places like Beijing and Shanghai made it difficult to register even used China III motorcycles with new plates. Therefore, when buying a motorcycle in 2021, you had to choose models meeting at least China IV standards, otherwise it would be money wasted. The policy is a hard rule, and manufacturers had already shifted to producing new standard vehicles. Everyone should pay extra attention when purchasing bikes - always verify the emission level before buying to avoid getting scammed.

This topic reminds me of the importance of environmental protection. The reason why China III motorcycles couldn't be registered in 2021 is mainly due to their high pollution levels and failure to meet emission standards. To improve air quality, the government has been promoting China IV and China V standards for several years. New vehicles must keep up with these requirements, otherwise the DMV will directly reject the registration application. As someone who cares about the environment, I support such measures because improved air quality means easier breathing for everyone. When buying a new motorcycle, pay attention to the manufacturing date and emission certification. China III models produced in 2021 absolutely cannot be registered - I recommend choosing China IV or above models which are both compliant and durable.

Having spent a lot of time in repair shops, I've encountered many similar issues. A brand-new 2021 China III motorcycle definitely can't be registered—the emission standard is too low. China IV became the minimum threshold two or three years ago. However, if it's a used bike or a refurbished old model, you might get lucky and have a chance at registration, but new models are completely out of the question. I always remind customers to check the emission certificate first when they ask. For new bikes, starting with China IV is the safer bet. Policies change, and we have to adapt—the registration system automatically filters out vehicles with lower standards. It's best to familiarize yourself with local regulations to avoid buying the wrong model and wasting time.
