Patent ID: 8888107

Claim:
A motorcycle comprising: a rear suspension and a front fork, and a hydraulic pump for the rear suspension and the front fork, the rear suspension including a hydraulic jack with a plunger thrust by hydraulic oil discharged by the hydraulic pump and a suspension spring supported by the plunger of the hydraulic jack, the hydraulic jack being actuated in a controllable manner based on a detection result from rear-wheel-side vehicle height detection means attached to the rear suspension to thereby adjust a rear-wheel-side vehicle height, the front fork including a hydraulic jack with a plunger thrust by hydraulic oil discharged by the hydraulic pump and a suspension spring supported by the plunger of the hydraulic jack, the hydraulic jack being actuated in a controllable manner based on a detection result from front-wheel-side vehicle height detection means attached to the front fork to thereby adjust a front-wheel-side vehicle height, wherein a vehicle height of the whole of the motorcycle is adjusted by interlocking a rear-wheel-side vehicle height adjusting operation based on controllable actuation of the hydraulic jack provided in the rear suspension, with a front-wheel-side vehicle height adjusting operation based on controllable actuation of the hydraulic jack provided in the front fork, wherein, in one of a front-wheel-side vehicle height adjustment device and a rear-wheel-side vehicle height adjustment device each having independent right and left pump functions, when one of the right and left pump functions fails, only the other of the pump functions performs control, and the failed pump function avoids performing control.
