In regular shock absorbers, bump rubber is vital to avoid damage from bottoming out. Unfortunately it causes instability, because when a large impact compresses it, energy thus amassed is released upwards.

RX1 however uses the Hydraulic Bump Stopper to convert the impact to thermal energy and absorb it. This strongly reduces the shock, and there's no repulsion force. Swiftly absorbing the impact of big jumps, H.B.S. produces a much more stable vehicle. In shock absorbers with inactive or no H.B.S., the operative valve (green) floats, and oil flows freely through the base valve ports. Resistance to the flow from the shim stack then, causes damping force.Near full compression, when the piston rod strokes beyond a predetermined point, the operative valve is pushed down and activates H.B.S.: the base valve ports are narrowed, blocking the oil flow. This results in high damping force.A relief valve serves to suppress sudden damping force increase, when the pressure in the cylinder exceeds its regular level.The setup of the H.B.S. mechanism is optimized per vehicle model, with the right activation point and damping force.

 

Advantage: adjusting ride height has little effect on ride quality. RX1 features 16-level damping force adjustment, for simultaneous adjustment of compression and rebound.Modify ride comfort and handling according to your preference, changing the properties of the shock absorber with the adjustment dial.

NOTE:RR: INTERIOR NEEDS TO BE REMOVED, MODIFIED AND/OR RELOCATED TO AVOID INTERFERENCE WITH THE MOTOR.

[ Characteristics ]
THE ORIGINAL CAR'S FRONT-TO-REAR ROLL RESISTANCE BALANCE, WHEN GOING OVER UNDULATIONS AND GAPS AND/OR AT CORNERS, IS IMPROVED, IN ORDER TO PROVIDE OVERALL FLAT RIDE FEEL FOR COMFORTABLE RIDE ON STREETS AND HIGHWAYS EVEN IN REAR SEATS. H.B.S. MAKES EFFECTIVE USE OF COMPRESSION STROKE, IN ORDER TO PROVIDE BETTER TRACTION PERFORMANCE AND CONTROLLABILITY.
