A gas chamber A expandable/compressible with extension/contraction of the front fork 4 is formed in the front fork 4, and gas stored in the gas chamber A generates reaction force in response to an extension/contraction amount of the front fork 4. The motorcycle includes a storage chamber B formed in the body frame 1 for storing gas therein, a passage 5 making the storage chamber B communicate with the gas chamber A, and a regulator 50 capable of supplying the gas to the gas chamber A from the storage chamber B.
