Motorcycle including brake-by-wire system with flexibly supported pressure-generating unit

A motorcycle comprising:

• a body frame comprising left and right seat rails which are spaced apart from one another and provided to support a seat thereon;
• an engine mounted on said body frame, 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, and
• a control unit for controlling the operation of said pressure-regulating unit on the basis of a signal from said operating amount detector, said pressure-regulating unit being disposed on the rear side of said engine body,
• wherein as seen in a top plan view thereof, said fluid pressure-generating unit is disposed between and supported by said left and right seat rails;
• wherein said fluid pressure-generating unit is flexibly supported, through a flexibly resilient member, by a first support member which is attached to one of said seat rails, and by a crossmember which extends between and connects both said seat rails;
• and wherein a second support member is firmly attached to said crossmember, and an attaching member, fixed to said fluid pressure-generating unit, is supported by said second support member through a flexibly resilient member.

A motorcycle comprising:

• a body frame comprising left and right seat rails which are spaced apart from one another and provided to support a seat thereon;
• an engine mounted on said body frame, said engine comprising an engine body;
• a wheel brake;
• a manually operable brake operating element which is fluidly connected to said wheel brake;
• a swing arm which is pivotally attached to said body frame and is supported for reciprocal movement thereon;
• a rear wheel which is rotatably attached to said swing arm;
• a link mechanism provided between said swing arm and said body frame, said link mechanism comprising a link member;
• a shock absorber extending between said swing arm and said link member;
• and
• a sub-tank for conditioning a damping force of said shock absorber, said sub-tank disposed on the rear side of said fluid pressure-generating unit and supported by said seat rail;
• 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, and
• a control unit for controlling the operation of said pressure-regulating unit on the basis of a signal from said operating amount detector, said pressure-regulating unit being disposed on the rear side of said engine body,
• wherein as seen in a top plan view thereof, said fluid pressure-generating unit is disposed between and supported by said left and right seat rails.
