In January 2025, China’s Ministry of Industry and Information Technology (MIIT), in collaboration with the Sub-Technical Committee for Motorcycles under the National Technical Committee of Auto Standardization, released the draft revision of the mandatory national standard titled “Performance and Measurement Method for Braking of Motorcycles and Mopeds.” This marks a significant update in China’s regulatory framework for two-wheeled vehicle safety.
The draft for comments was released on April 30, 2025 and the The deadline for submitting comments is June 30, 2025. If you have any feedback or suggestions, please provide them in written form. Individual submissions should include the sender’s name; organizational submissions should be stamped with the official seal and include contact details.

The brief of the mandatory standard is as follows
The draft revision of the mandatory national standard “Performance and Measurement Method for Braking of Motorcycles and Mopeds.”, which replaces the 2018 version, applies to motorcycles and mopeds powered by internal combustion engines, electric motors, or hybrid systems. It excludes off-road motorcycles and vehicles for persons with disabilities. The revision is the fifth of its kind and was developed with reference to international regulations such as UNECE Regulation No. 78, UN GTR No. 3, and EU Regulation (EU) No. 168/2013. It also considers domestic industry conditions, supply chain capabilities, and vehicle safety requirements.
A major focus of the updated standard is the enhancement of braking system safety and compatibility with advanced technologies. It specifies detailed requirements for anti-lock braking systems (ABS), combined braking systems (CBS), electronic control systems, and regenerative braking systems. The draft mandates that two-wheeled motorcycles with engine displacements over 125mL or with electric motors exceeding 2.0 kW must be equipped with either ABS or CBS. Electric motorcycles with motor power above 4.0 kW are required to install ABS. These provisions reflect China's commitment to harmonizing with global safety practices.
To ensure performance reliability, the standard defines metrics such as mean fully developed deceleration, stopping distance, and conditions for high-speed, wet-surface, and hill-start tests. It introduces requirements for emergency braking signal activation, electromagnetic compatibility (EMC), and the logic governing brake light signals.
Notably, the draft introduces safety provisions for composite electronic control systems that include automatic braking functions. These systems must have clear fault management strategies and may not be deactivated during testing. A new annex on type extension requirements is also included, covering parameters such as drive type, maximum design speed, curb and gross weight, transmission specifications, tire models, and braking configurations.
According to the draft, the revised standard will apply to newly approved vehicle types starting from the implementation date. For vehicle types with existing type approval, compliance will be mandatory starting from the 25th month after the effective date. As some technical clauses deviate from international standards and involve public safety, the draft will be submitted for WTO/TBT notification in accordance with China’s regulations on mandatory standards.
The revision and enforcement of this standard are expected to significantly improve the braking safety of motorcycles and mopeds in China, promote the adoption of advanced braking technologies, and support the alignment of national regulations with international best practices.
