The invention relates to the technical field of motorcycles, and discloses a motorcycle protraction angle adjusting mechanism, flange seats are detachably mounted at the top and the bottom of a frame, bearing rings are embedded in the flange seats, oil seal rings are embedded between the bottoms of the bearing rings and the flange seats, frame holes are coaxial up and down (coaxial with the outer circles of the flange seats), and the oil seal rings are embedded in the flange seats. A set included angle is machined between the inner circle (bearing press-fitting surface) of the flange and the outer circle axis of the flange; a user can take out the upper flange base and the lower flange base according to needs, rotate the upper flange base and the lower flange base by 180 degrees and then assemble the flange bases into a frame, and the forward extending angle can be adjusted When in use, the size of the front extension angle of the whole vehicle can be adjusted according to the use requirements of the vehicle, so that not only can the control sensitivity during driving under a racing track limit be met, but also the high-speed stability during long-distance riding of a friction trip can be met, and different driving experiences and driving fun can be brought by one vehicle.

    本发明涉及摩托车技术领域,公开了一种摩托车前伸角调节机构,所述车架的顶部与底部均可拆卸安装有法兰座,所述法兰座的内部嵌设有轴承圈,所述轴承圈的底部与法兰座之间嵌设有油封圈,车架孔上下同轴(与法兰座外圆同轴),法兰内圆(轴承压装面)与法兰外圆轴线加工设定夹角;用户可根据需要将上下法兰座取出各自旋转180°再装配进车架中,前伸角便可调整;使用时可以根据车辆使用需求调整整车的前伸角大小,这样既能满足下赛道极限驾驶时的操控灵敏性,也能满足摩旅长途骑行时的高速稳定性,一辆车就能带来不同的驾驶体验和驾驶乐趣。
