A ride-height robust sensor measures shock absorber travel and monitors absolute ride-height in a front and rear shock absorber of a motorcycle regardless of varying cargo weights. Rather than modifying the frame, the sensor is mountable directly to a motorcycle rear shock absorber using a novel upper mount and lower mount. A second sensor is mountable to a front shock absorber using a novel ride-height upper fork bracket and ride-height lower fork bracket. A novel ride-height display module and attendant control module provide a visual display of shock height using a multicolored six LED array. User-customised ride-height and dismount height are activated upon motor ignition and cutoff using a solenoid control module. Components are electronically isolated from the motorcycle ignition system and shock solenoids for accuracy and reliability. The ride-height controller enters sleep mode when not in use and is installable by the user.

A front fork of a bicycle may include a suspension system that includes a damper. The damper may include a hollow tube with orifices that may be partially blocked by an adjustable blocker. A free end of the adjuster that adjusts the blocker may maintain its axial position in any rotational position. Ambient air may be introduced through a valve and retained in the suspension system. The suspension may include a mechanical spring in a chamber away from the valve that introduces the ambient air.

An object is to provide a front fork including a stroke sensor as well as a damping force variable device, and allowing structure of the front fork to be simplified. A front fork of an embodiment includes a pair of a first leg and a second leg. The first leg includes a stroke sensor section that detects a stroke amount of the front fork as a distance between extension and compression of the front fork. The second leg includes a damping force variable device that controls a flow of a working fluid contained in the second leg to enable a damping force to be varied.

The present invention relates to a spring unit (1) for a shock absorber (100) intended for a vehicle. The shock absorber (100) comprises a damping cylinder (101), wherein the damping cylinder (101) is adapted to be telescopically arranged within the spring unit (1). The spring unit (1) comprises a hollow body (2) comprising at least one compression chamber (2b) and at least one additional chamber (3) arranged to be in fluid communication with the compression chamber such that at least a first flow of fluid (F1) is adapted to be allowed between the compression chamber (2b) and the additional chamber (3) when a threshold value is met. The invention further relates to a shock absorber (100) comprising such a spring unit (1), and a front fork comprising such a shock absorber (100) as well as a method for filling the shock absorber (100).

Providing a sealing member which can successfully scrape off foreign substances and prevent failure caused by incorporation of foreign substances. A dust seal serving as a sealing member includes a dust seal body and a lip member. The dust seal body has a predetermined elasticity and is retained in an opening of an outer tube into which an inner tube reciprocated in a projected state is inserted. The lip member is harder than the dust seal body and is attached to a distal end of the dust seal body. The lip member has a distal end which is brought into sliding contact with an outer peripheral surface of the inner tube.

An arrangement for the temporary pre-tensioning of fork tubes (1, 2) of a telescoping fork, displaceable with respect to each other, comprises a base body (3) attached to a first fork tube (1) to secure and guide at least a first locking element (4) and a second locking element (5), whereby the locking elements (4, 5) interact with a receptacle element (6) attached to the second fork tube (2). A common actuation element (7) is provided within the housing of the base body (3) to actuate the locking elements (4,5).
