Front forks for bicycles are described herein. An example front fork includes an upper fork including a first leg and a second leg, a lower fork including a third leg disposed along the first leg and a fourth leg disposed along the second leg, a first set of links rotatably coupled between the first leg and the third leg, and a second set of links rotatably coupled between the second leg and the fourth leg. The first and second sets of links enable the lower fork to swing relative to the upper fork. The front fork also includes a steerer tube coupled to the front fork and a spring in the steerer tube. The spring is configured to bias the lower fork away from the steer tube.

A bicycle comprising a frame; a handlebar assembly attached to an upper steering tube of the frame in such a way that at least the relative rotation between the two with respect to an upper axis is allowed, but the relative displacements between both in the directions perpendicular to the upper axis are restricted; a fork attached to a lower steering tube of the frame so that it has the same degrees of freedom relative to the lower axis between the fork and the lower steering tube as the degrees of freedom relative to the upper axis between the handlebar assembly and the upper steering tube; and a means for rotation transmission for transmitting at least partially a rotation of the handlebar assembly with respect to the upper tube into a rotation of the fork with respect to the lower steering tube.

A motorcycle includes: a front swing arm that includes upper arms and lower arms; a fork holder; a front fork; and a front cushion unit. The fork holder of a front-wheel suspension device includes a pair of left and right sideward extended portions which extend in the vehicle width direction. The front ends of the left and right upper arms are attached to the left and right sideward extended portions though connecting shafts, respectively.
