Abstract: A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.

Abstract: A method for controlling vehicle motion is described. The method includes: accessing a set of control signals, wherein at least a first control signal of the set of control signals includes a set of values associated a pressure applied to a vehicle component of a vehicle; accessing a set of predetermined vehicle component base-level pressure values associated with the vehicle component; comparing the set of values associated with a pressure applied to the vehicle component with the set of predetermined vehicle component base-level pressure values; based on said comparing, calculating an approximate shift in a center of gravity of the vehicle; monitoring a state of at least one valve; and based on the calculating and the monitoring, determining a control mode for said at least one vehicle suspension damper that, if actuated, would compensate the vehicle for the shift in the center of gravity.

Abstract: A motorcycle includes a frame, a fork, a from wheel, an upper arm, a lower arm, a handlebar, and a suspension element. The fork is pivotable with respect to the frame about a steering axis. The front wheel is rotatably coupled with the fork. The upper arm and the lower arm are each pivotally coupled with each of the fork and the frame. The handlebar is pivotally coupled with the frame and is configured to facilitate steering of the front wheel. The suspension element is coupled with each of the frame and the fork.

Abstract: A vehicle, such as a motorcycle, includes an engine and a frame. The engine includes a cylinder housing and a spark plug. The cylinder housing defines a spark plug aperture. The spark plug is received within the spark plug aperture. The frame supports the engine and comprises a frame member. The frame member is adjacent to the cylinder housing and defines an access aperture. The access aperture is substantially aligned with the spark plug aperture. The access aperture is configured to facilitate installation and removal of the spark plug with respect to the spark plug aperture. Methods of installing and replacing a spark plug are also provided.

Abstract: A half-track vehicle includes a frame, first and second beams having forward and rearward wheels attached thereto, and first and second suspension systems. The frame includes a first side and a second side, and the first suspension system suspends the first beam from the frame adjacent the first side of the frame and the second suspension system suspends the second beam from the frame adjacent the second side of the frame. Each suspension system includes at least one element, such as a trailing arm, and A-arm, and a transverse suspension member, that is attached to one of frame and an associated one of the first and second beams in a manner that permits three degrees of rotational movement and that transmits motive force from the first and second beams to the frame.
