Description

Technical Field

[0001] The utility model relates to the technical field of off-road motorcycles, in particular to a flat tube type off-road motorcycle frame. Background Art

[0002] Off-road motorcycles are designed for off-road riding. They can be ridden in harsh ground environments such as sand, mud, river beaches, mountains, and even rocky areas. Off-road motorcycles have a lightweight body, tires with thick patterns or particles, long suspension travel, and high ground clearance. You can easily perform various stunts such as head-turning, jumping, and flying uphill. In a nutshell, off-road motorcycles can take you across boulders and through the jungle. For this reason, it is particularly important that the frame of an off-road motorcycle has high strength and stability, so that it can meet the harsh ground riding environment. In order to achieve the needs of high strength and stability, the existing off-road motorcycles have a relatively complex frame structure design, and round steel pipes are generally used as frame materials. Considering the cost and lightweight design requirements, the traditional off-road motorcycle frame still has a lot of room for optimization. Utility Model Content
