Description

Technical Field

[0001] The utility model relates to the field of motorcycle accessories, in particular to a bumper suitable for large-displacement motorcycles. Background Art

[0002] When a motorcycle collides with other objects during driving, the guard bar fixed on the motorcycle can play a certain buffering role and reduce losses. The current motorcycle guard bars are more of a decorative role. When an accident actually occurs, the protective effect it produces is not very high. A motorcycle guard bar disclosed in the search application number CN202223403693.8 is recorded to include a left guard bar and a right guard bar. The front and rear ends of the left and right guard bars are respectively provided with front end fixing frames and rear end fixing frames fixed to the front and rear end frames of the vehicle body, and there are two sets of connecting fixing plates along the left and right parts of the inner side of the guard bar, which can be connected from the bottom of the motorcycle engine. The right front fixing frame and the left front fixing frame are flat, the left rear end fixing frame, the right rear end fixing frame, the right rear link fixing plate and the left rear link fixing plate, the right front link fixing plate and the left front link fixing plate are not fixed on the motorcycle engine. When an accidental collision with other objects occurs, no additional damage will be caused to the engine, and the motorcycle body can be protected. However, the device still has the following defects in actual use: although the motorcycle guard bar can protect the engine and the body in actual use, it is not suitable for large-displacement motorcycles. Its structure is relatively simple and cannot protect the rider's legs. Therefore, it is necessary to design a practical guard bar suitable for large-displacement motorcycles. Utility Model Content
