Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, and in particular to a high-strength motorcycle frame. Background Technology

[0002] Existing motorcycle frames have shortcomings in terms of collision protection and riding comfort. In the event of a collision, the frame lacks an effective cushioning and impact-distribution structure, making it susceptible to damage. Simultaneously, vibrations transmitted by the motor affect the riding experience, and the seat frame lacks cushioning design when the user sits down, resulting in poor comfort. To address these issues, this invention proposes a high-strength motorcycle frame. It utilizes a connecting tube on the side surface of the head tube, with a carbon fiber triangular tube fixed to the side surface of the connecting tube. Combined with a bent tube at the end of the triangular tube, it achieves cushioning and impact distribution during a collision, reducing frame damage. Furthermore, a double-arm tube is installed on the lower surface of the seat frame. Springs within the double-arm tube reduce vibration, and the seat frame can slide relative to the sliding tube and resist spring force when compressed, achieving cushioning and improving riding comfort.
