Abstract: A lean-steering stabilization device includes: a first hollow member; a second hollow member; a shaft extending into the first and second hollow members and secured to the second hollow member; a cam mechanism including a cam and a cam follower, the cam being provided on the second hollow member, the cam follower being provided on the first hollow member, the cam engaging the cam follower such that rotation of the cam relative to the cam follower about an axis results in movement of the cam relative to the cam follower along the axis; and a biasing member biased against the first hollow member and the shaft.
