In a spring leg of a front fork, the capacity of a rebound air spring chamber is expanded and a stable rebound reaction force is ensured, and the spring leg of the front fork is provided with a sub-tank including an air chamber communicating with a rebound air spring chamber.

A vehicle suspension system is disclosed. The vehicle suspension system can include a first spring having a first spring characteristic, a second spring having a second spring characteristic, and an actuator coupled to the first and second springs such that actuation of the actuator causes a change in the first and second spring characteristics. The change in the second spring characteristic can be inversely proportional to the change in the first spring characteristic to adjust vehicle handling.
