ABSTRACT:
Disclosed is a shock absorber for a water jet ski which comprises a cylinder-and-piston assembly, the cylinder and piston of which are pivotably attached to a water jet ski body and to the handlebar of the water jet ski respectively. The fluid filled in the cylinder is allowed to pass through the orifices of the piston body while the piston moves back and forward in the cylinder in response to the rise and descent of the handlebar. With this arrangement the rider can move up and down the handlebar so freely as to permit him to keep his balance on the water jet ski while running on water. The orifice size is selected to be appropriate for the purpose of preventing uncontrollable quick move of the handlebar which otherwise would be caused by sudden application of strong force to the water jet ski body, thereby preventing the rider from losing his balance on the water jet ski.
