Abstract

A two-wheeled vehicle includes a frame, a front ground-engaging member, a rear ground-engaging member, and a rear suspension assembly operably coupled to the rear ground-engaging member. The rear suspension assembly includes a first swing arm, a second swing arm, and a pivot axle extending between the first and second swing arms. And, rotation of the pivot axle is configured to adjust the position of a portion of the frame relative to the first and second swing arms.

First claim

What is claimed is:

1 . A two-wheeled vehicle, comprising:
a frame assembly including:
a front frame portion including a head portion, a plurality of generally vertically-extending frame tubes, and a plurality of generally longitudinally-extending frame tubes;
a mid-frame portion removably coupled to the front frame portion; and
a rear frame portion removably coupled to the mid-frame portion;
a front ground-engaging member for supporting the frame assembly; a rear ground-engaging member for supporting the frame assembly; and a rear suspension assembly operably coupled to the rear ground-engaging member, the rear suspension assembly including a first swing arm coupled to the mid-frame portion, a second swing arm coupled to the mid-frame portion, and a pivot axle extending between the first and second swing arms, wherein rotation of the pivot axle is configured to adjust the position of the mid-frame portion relative to the first and second swing arms.

2 . The two-wheeled vehicle of claim 1 , wherein the pivot axle includes an internally-profiled surface configured to receive a tool for rotating the pivot axle.

3 . The two-wheeled vehicle of claim 1 , wherein an end of the pivot axle is threadedly received within an aperture of the mid-frame portion.

4 . The two-wheeled vehicle of claim 1 , wherein a first fastener is received within a first end of the pivot axle and extends from a second end of the pivot axle to couple with a second fastener positioned outwardly from one of the first and second swing arms.

5 . The two-wheeled vehicle of claim 1 , wherein the mid-frame portion is cast.

6 . The two-wheeled vehicle of claim 5 , wherein the mid-frame portion is configured to move inwardly and outwardly in response to the rotation of the pivot axle.

7 . The two-wheeled vehicle of claim 1 , further comprising a rear axle operably coupled to the rear ground-engaging member and a drive assembly operably coupled to the rear axle, the drive assembly includes an adjustment member for adjusting the position of the rear axle.

8 . The two-wheeled vehicle of claim 7 , wherein the adjustment member includes a head portion and a post portion, the head portion includes an aperture for receiving the rear axle, and the post portion extends rearwardly from the rear axle.

9 . The two-wheeled vehicle of claim 1 , wherein the rear frame portion is coupled to the mid-frame portion with a plurality of longitudinally-extending fasteners.

10 . The two-wheeled vehicle of claim 1 , further comprising a rear fender coupled to the rear frame portion, and the rear fender has a shape complementary to that of the rear frame portion.

11 . The two-wheeled vehicle of claim 10 , wherein a forward end of the rear fender includes a recess adjacent to the swing arm.

12 . The two-wheeled vehicle of claim 1 , wherein the rear suspension assembly includes a first shock absorber operably coupled to the first swing arm and a second shock absorber operably coupled to the second swing arm, an upper end of the first shock absorber is angled forwardly relative to a lower end of the first shock absorber, and an upper end of the second shock absorber is angled forwardly relative to a lower end of the second shock absorber.

13 . The two-wheeled vehicle of claim 12 , wherein the upper ends of the first and second shock absorbers are coupled to the mid-frame portion, and the lower ends of the first and second shock absorbers are coupled to the first and second swing arms.

14 . The two-wheeled vehicle of claim 13 , wherein the upper ends of the first and second shock absorbers are angled forwardly approximately 45 degrees relative to the first and second swing arms.
