Due to factors such as the shape, size, azimuth, and hardness of these components, it may cause physical injury to pedestrian or driver when a motorcycle and pedestrian encounter a traffic accident such as collision or scraping. 5.1.1.2 When used on a road, the design of components that may touch other's body shall meet the requirements of 5.1.2. 5.1.1.3 External projections made of soft rubber, plastic or covered by these materials with Shore hardness less than A60 (HA) are considered to meet the requirements of 5.1.2. 5.1.1.4 If the two-wheeled motorcycle is equipped with a panel for closing or partially closing the components of the driver, passenger or motorcycle, then the vehicle manufacturer can choose whether the motorcycle is a special enclosed part, OR the external projection of the vehicle meets the requirements of GB 11566. If only the closed part meets the requirements of GB 11566, then the external projections of the rest shall meet the requirements of 5.1.2. At the same time, the company must clearly explain the applicable standards of this part in the corresponding technical documents. 5.1.2 Special technical requirements 5.1.2.1 Requirements for radius of curvature of group 1 parts 5.1.2.1.1 Plate - The radius of curvature of each corner of the plate shall not be less than 3.0 mm; - The radius of curvature of the edge of the plate shall not be less than 0.5 mm. 5.1.2.1.2 Stem - The diameter of stem or similar parts shall not be less than 10 mm; - The radius of curvature of the end of the stem shall not be less than 2.0 mm. 5.1.2.2 Requirements for radius of curvature of group 2 parts 5.1.2.2.1 Plate of GB 11566. 5.2.2.2 For the right tricycle that can clearly see the front forks, wheels, bumpers, fenders, shrouds, trunks and other components, the manufacturer can choose whether the tricycle meets the requirements of GB 11566 or 5.1.
