自動二輪車のフレーム
Document Type and Number:
Japanese Patent JP4630754
Kind Code:
B2
Abstract:
A lightweight motorcycle frame is made with sufficient rigidity to minimize or avoid the occurrence of frame cracks, due to impacts on the frame caused by a harsh landing after a vehicle jump or the like. The motorcycle frame includes a head pipe, a pair of main frames extending rearwardly from the head pipe, and a down tube extending downwardly from a lower portion of the head pipe. The frame may include a forged reinforcing body for connecting the head pipe and the down tube, and the other frame components may be formed by casting. In this case, the other frame components include a portion of the head pipe, the main frames, the down tube, and the reinforcing frame, which may be integrally molded by aluminum casting. Where used, the reinforcing body may be secured to a front portion of an integrally cast frame body.
