[0002] As the core load-bearing structure of the whole vehicle, motorcycle frames are widely used in various motorcycle designs, and their rigidity and damping performance directly affect the controllability, comfort and safety of the vehicle. Traditional motorcycle frames mostly adopt cradle-type structures, and the engine is usually installed in the cradle space at the lower part of the frame and fixed through rigid connection or simple cushioning. However, the motorcycle engine will produce strong periodic vibration during operation, especially for single-cylinder or double-cylinder engines, and the vibration frequency is easy to couple with the natural frequency of the frame, causing overall resonance of the frame.

[0003] This resonance phenomenon not only reduces the riding comfort and aggravates the driver's fatigue, but also may cause metal fatigue of the welding points or connecting parts of the frame, leading to structural loosening or even breaking after long-term use, which seriously affects the driving safety. In addition, excessive vibration will also be transmitted to other key components such as fuel tank, instruments and lamps, accelerating their aging or damage. Therefore, how to effectively isolate engine vibration and avoid its direct transmission to the frame has become an important issue in motorcycle design. SUMMARY
