Abstract
A motorcycle includes a rear fork with a first and the second extending portions, and a cross portion, the cross section linking the first and the second extending portions together. The first extending portion extends toward a first side of a rear wheel, the second extending portion extends toward a second side of the rear wheel. The first extending portion, which has an open cross sectional structure and through which a drive shaft is passed, is made to have larger outer diameter than the second extending portion, which has a closed cross sectional structure. Nonetheless, the rigidity of the first extending portion and the second extending portion are approximately the same. The drive shaft extends rearwardly and passes through the opening on the inside of the first extending portion.
