Patent ID: 8287053

Claim:
A motorcycle, comprising: a body frame comprising left and right frame sections which are spaced apart from one another; and a crossmember which connects said left and right frame sections; a support member which is flexibly supported between said left and right frame sections through a plurality of flexibly resilient members, said support member also operatively connected to said crossmember; an engine mounted on said body frame such that said left and right frame sections are disposed on left and right sides of said engine, respectively, and said crossmember is disposed at a rear side of said engine, said engine comprising an engine body; a wheel brake; a manually operable brake operating element which is fluidly connected to said wheel brake; and a brake-by wire system, comprising: an operation amount detector for detecting an amount of force applied to the brake operating element; a fluid pressure-generating unit capable of-generating a fluid pressure independently from an operation of said brake operating element; a pressure-regulating unit interposed between said fluid pressure-generating unit and a wheel brake for regulating an output fluid pressure of said fluid pressure-generating unit and applying the regulated fluid pressure to said wheel brake, wherein said pressure-regulating unit is attached to said support member; and a control unit for controlling operation of said pressure-regulating unit on the basis of a signal received from said operating amount detector, said pressure-regulating unit being disposed on the rear side of said engine body; wherein the support member comprises: an outer bracket member having a central connecting portion and two downwardly extending side portions, each of the side portions of the outer bracket member having an attaching arm part extending outwardly thereon which is operatively attached to a respective adjacent one of said frame members; an inner bracket member having a central connecting portion and two downwardly extending side portions, the inner bracket member fitting nestingly inside of the outer bracket member central connecting portion and two downwardly extending side portions; and a plurality of rubber bushings operable to help isolate the pressure-regulating unit from vibration.
