What is the Emission Standard for Motorcycles?
4 Answers
Motorcycle emission standard is China III. Below are the specific details regarding motorcycle emission standards: Regulatory Standards: Starting one year after the specified type approval implementation date, all manufactured, sold, and registered motorcycles and mopeds must comply with the above emission standard requirements. China III Standard: Domestically manufactured and sold motorcycles and mopeds currently adhere to the China II emission standard. However, according to newly enacted regulations, newly certified models must meet the China III standard and be mass-produced accordingly. Additionally, all manufactured, sold, and registered motorcycles and mopeds must complete the transition to meet the China III emission standard within a specified timeframe.
Hi, I've been riding motorcycles for over a decade. Nowadays, the emission standards are mostly China IV, especially for those manufactured after 2018, the vast majority meet the standards. I used to ride a China III bike, which had strong exhaust fumes and emitted black smoke, but the new standard bikes don't have these issues. The country is promoting the China IV standard to reduce pollution and improve urban air quality, so I support upgrading to new bikes earlier. When buying a used motorcycle, check the vehicle nameplate or registration certificate to confirm the emission level to avoid future inspection troubles. Currently, there's a transition to China V, with some new bikes already upgraded to cleaner catalysts, but overall China IV remains the mainstream. For older bikes, maintaining the three-way catalytic converter well can reduce emissions and save fuel, avoiding environmental fines. This change is really great, allowing everyone to share a better environment.
I really care about environmental protection. The emission standards of motorcycles directly affect air quality, so most current models are at the China IV level. Older China III motorcycles are still on the road, but they face many restrictions in urban centers due to high pollution. Stricter standards force manufacturers to improve engines and reduce harmful gases like nitrogen oxides and carbon monoxide. I remember that after the full implementation of China IV, smoggy days decreased significantly, which is great for health. The government also introduced subsidies for scrapping old vehicles to encourage upgrades, and now almost all new vehicles start at China IV. Checking emission standards is easy—just look at the vehicle manual or search the VIN online. It's important because air pollution is extremely harmful, especially to children who are more prone to illness. I suggest everyone use vehicles with the latest standards to contribute to the planet.
When it comes to motorcycle emissions, the standards are generally dominated by China IV, with levels determined by the manufacturing year. New motorcycles after 2020 are all China IV or above, with changes in engine design such as adding high-efficiency catalytic converters to control pollution. There are still many older motorcycles meeting China III standards, but they struggle to pass tailpipe emission tests. Key parameters include CO and NOx limits, with China IV being much stricter than older versions. Vehicle information is clearly stated on the compliance certificate or environmental label. The current trend is towards China V, which demands higher purification efficiency but is being adopted more slowly. The difference in daily riding experience is minimal, but the long-term environmental impact is significant.
