VEHICLE BODY STRUCTURE OF MOTORCYCLE

PROBLEM TO BE SOLVED: To reduce the weight of a vehicle body frame including a cross member by reducing the burden on the cross member by the load transmitted from a swing arm via a rear suspension. SOLUTION: In this structure, the vehicle body frame 10 and the swing arm 11 for rear wheels vertically oscillatably supported on the vehicle body frame 10 are provided, and the rear suspension 12 is interposed between the vehicle body frame 10 and the swing arm 11. The vehicle body frame 10 has a pair of left and right main frame members 20L and 20R extending backward from a head pipe 25 and the cross member 26 for connecting rear end parts of the left and right main frames. The cross member 26 has a supporting boss 63 for oscillatably supporting an end part of the rear suspension 12 in a connecting part with the main frame 20R. An oscillating fulcrum P of the rear suspension 12 in the supporting boss 63 is arranged on the same axial center O2 as the cross member 26. COPYRIGHT: (C)2007,JPO&INPIT
