The fluid supply device comprises a screw, which has a male thread formed thereon and rotates, and a nut, which has a female thread formed therein that meshes with the male threading and which, by the screw rotating in a first direction, i.e., the circumferential direction, moves towards a first end in the rotation axis direction, and which, by moving with said movement a piston that forms a reservoir chamber, discharges a fluid stored in the reservoir chamber, wherein, if the fluid is discharged and if the screw is not rotating, first surfaces which form the threading of the male screw and second surfaces which form the threading of the female screw are in contact with each other, and second surfaces which form the threading of the male screw and first surfaces which form the threading of the female screw are not in contact with each other.

A system and method for utilizing an active valve customizable tune application is disclosed. The system initiates an active valve tune application. Receive a suspension tune for a vehicle, the suspension tune comprising a number of performance range adjustable settings. Presents the suspension tune within the active valve tune application on the display. Receive input to modify, at the active valve tune application, one or more of the number of performance range adjustable settings. Generates a modified suspension tune based on the modification input.

A control apparatus for a suspension apparatus, includes: a vehicle speed acquiring section which acquires a vehicle speed as a speed of a vehicle; an acquisition section which acquires a stroke velocity of the suspension apparatus; a contribution ratio determining section which determines a contribution ratio between a first parameter and a second parameter based on the vehicle speed, the first parameter serving for controlling a damping force in a first speed region of the vehicle, the second parameter serving for controlling the damping force in a second speed region which is a speed region higher in speed than the first speed region; a change amount restricting section which restricts a change amount of the contribution ratio; and a damping force controlling section which controls the damping force of the suspension apparatus based on the restricted contribution ratio and the stroke velocity.

A straddle vehicle of the present invention includes: a vehicle body frame member; a rotatably supporting member supporting a front wheel; a support arm supporting the rotatably supporting member, the support arm extending rearward from the rotatably supporting member; a pair of upper and lower link members pivotally connected to the support arm at two locations on a rear portion of the support arm at least on one side of the vehicle body in a vehicle width direction, the two locations being spaced in the upward-downward direction, the pair of upper and lower link members extending rearward from the support arm, each of the link members having a rear portion pivotally connected to the vehicle body frame member; a handle; and a handle supporting member removably coupled to the vehicle body frame member and supporting the handle.

An active air spring regulates and controls compression and rebound travel, speed, and shock position by modulating internal pressures in an air bag and/or air cylinder in real time by varying the internal volume of discrete air reservoirs in fluid connection with one another as controlled by valves, venting, and self-pressurization.

Altering the damping rate of a vehicle suspension damper. A pressure of a damping fluid is exerted against a second valve mechanism connected to the vehicle suspension damper. The pressure of the damping fluid is increased beyond a threshold of the second valve mechanism that is adjustable by an adjustment member. The adjustment member is exposed through a high pressure side of the vehicle suspension damper. The second valve mechanism is then opened.

A motorcycle includes: a front swing arm that includes upper arms and lower arms; a fork holder; a front fork; and a front cushion unit. The fork holder of a front-wheel suspension device includes a pair of left and right sideward extended portions which extend in the vehicle width direction. The front ends of the left and right upper arms are attached to the left and right sideward extended portions though connecting shafts, respectively.

The integrated tank and compressor mounting system for a motorcycle has a mount block which has a mounting face, and a compressor clamp. The mount block has a threaded cylindrical section which forms a tank mount for mounting a tank. The tank has a cylindrical tubular section closed at one end and threaded at the other end such that the tank threads correspond to the mount block threads. The tank provides air for an air suspension which includes a forward suspension unit activated by air and an aft suspension unit activated by air. A supply line connects the tank air volume to an inlet valve on the suspension control unit. The suspension control unit has a cylindrical forward control valve passage and the forward control valve passage has a forward transfer chamber.

Methods and apparatus for regulating the function of a suspension system are disclosed herein. Suspension characteristics often contribute to the efficiency of a suspended system. Depending on the desired operating parameters of the suspended system, it may be desirable to alter the functional characteristics of the suspension from time to time in order to maintain or increase efficiency. The suspension hereof may be selectively locked into a substantially rigid configuration, and the damping fluid may be phase separated and/or cooled to increase damping rate during use (or offset rate degradation). The suspension hereof may generate power usable to achieve any or all of the foregoing or to be stored for use elsewhere in the suspended system or beyond.

A hydraulic flow adjuster includes a first hydraulic tank, a second hydraulic tank, and a piston actuator. A first piston operates within the first hydraulic tank and a second piston operates within the second hydraulic tank. The piston actuator adjusts a relative position of the first piston in the first hydraulic tank and a relative position of the second piston position in the second hydraulic tank, such that the relative position of the first piston in the first hydraulic tank is the same as the relative position of the second piston in the second hydraulic tank.
