What is the difference between China III and China IV motorcycle standards?

[SiennaLee]

Motorcycle China III and China IV standards mainly differ in reduced sulfur content and greater reductions in pollutant emissions. Here is relevant information: 1. The biggest difference between China IV and China III motorcycles is the improved emission standards. With higher emission standards, the price and performance of motorcycles undergo some changes. To meet these standards, China IV motorcycles have replaced traditional carburetors with electronic fuel injection systems and upgraded the exhaust systems. 2. The China III motorcycle standard was implemented starting July 1, 2010. For motorcycle manufacturers, China III motorcycles required not only improvements in production technology but also considerations of production costs and market sales. Many owners worry that after the formal implementation of the China IV policy, China III motorcycles cannot be registered. However, as long as the vehicle management office can scan and approve the vehicle's certification, even China III emission motorcycles can be registered if they pass the inspection.
