A motorcycle including a main frame, a rear swing frame, and a pull shock assembly operatively disposed between the main frame and the rear swing frame. The swing frame is pivotally mounted to the main frame. The main frame includes a pair of slide tracks that receive a slide member of the pull shock assembly. A link arm extends between a forward portion of the swing frame and the slide member, and translates pivotal movement of the swing frame into sliding longitudinal movement of the slide member. A damper associated with the slide member restricts sliding movement of the slide member and, thus, pivotal movement of the swing frame. The link has a forward end secured to the swing frame and a rearward end secured to the slide member.

What is claimed is: 1. A motorcycle subassembly, comprising: a main frame, said main frame having a forward end and a rearward end; and, a rear suspension assembly, comprising: a rear swing frame, said swing frame being pivotally secured to said main frame and defining a pivoting axis; and, a pull
What is claimed is: 1. A motorcycle subassembly, comprising: a main frame, said main frame having a forward end and a rearward end; and, a rear suspension assembly, comprising: a rear swing frame, said swing frame being pivotally secured to said main frame and defining a pivoting axis; and, a pull shock assembly, said pull shock assembly including a slide member and a damper, said slide member being slidably secured to said main frame at a location that is rearward of the pivoting axis, while said damper is affixed to said slide member and to said main frame, said slide member being operatively associated with said rear swing frame; wherein, pivotal movement of said rear swing frame relative to said main frame causes said slide member to slidably move relative to said main frame against a biasing force of said damper. 2. The motorcycle subassembly according to claim 1, wherein said main frame includes a slide track that receives said slide member. 3. The motorcycle subassembly according to claim 2, wherein said pull shock assembly further comprises a link that extends between said rear swing frame and said slide member, said link forcing said slide member to slidably move relative to said main frame upon pivotal movement of said rear swing frame relative to said main frame. 4. The motorcycle subassembly according to claim 3, wherein said link includes a forward end that is pivotally secured to said rear swing frame and a rearward end that is pivotally secured to said slide member. 5. The motorcycle subassembly according to claim 4, wherein said link forward end is disposed relatively forward of the pivoting axis while said link rearward end is disposed relatively rearward of the pivoting axis. 6. A motorcycle subassembly, comprising: a main frame, said main frame having a forward end and a rearward end; and, a rear suspension assembly, comprising: a rear swing frame, said swing frame being pivotally secured to said main frame; and, a pull shock assembly, said pull shock assembly including a slide member and a damper, said slide member being slidably secured to said main frame while said damper is affixed to said slide member and to said main frame, said slide member being operatively associated with said rear swing frame; wherein, pivotal movement of said rear swing frame relative to said main frame causes said slide member to slidably move relative to said main frame against a biasing force of said damper and wherein said pull shock assembly further comprises a link that extends between said rear swing frame and said slide member, said link forcing said slide member to slidably move relative to said main frame upon pivotal movement of said rear swing frame relative to said main frame. 7. The motorcycle subassembly according to claim 6, wherein said main frame includes a slide track that receives said slide member. 8. The motorcycle subassembly according to claim 6, wherein said link includes a forward end secured to said rear swing frame and a rearward end that is secured to said slide member. 9. The motorcycle subassembly according to claim 8, wherein said link forward end is pivotally secured to said rear swing frame and said link rearward end is pivotally secured to said slide member. 10. The motorcycle subassembly according to claim 9, wherein said main frame includes a slide track that receives said slide member. 11. The motorcycle subassembly according to claim 8, wherein said link forward end is disposed relatively forward of the pivotal connection between said rear swing frame and said main frame. 12. The motorcycle subassembly according to claim 11, wherein said link forward end is pivotally secured to said rear swing frame and said link rearward end is pivotally secured to said slide member. 13. The motorcycle subassembly according to claim 12, wherein said main frame includes a slide track that receives said slide member. 14. A motorcycle assembly, comprising: a main frame, said main frame having a forward end and a rearward end, said rearward end of said main frame including a slide track; a front wheel operatively secured to said main frame and defining a first rotational axis; a rear suspension assembly, comprising: a rear swing frame, said swing frame being pivotally secured about a pivoting axis to said main frame rearward end at a location relatively forward of said slide track; and, a shock assembly that includes a slide member and a damper, said slide member being slidably received within said slide track provided by said main frame rearward end while said damper is affixed to said slide member and to said main frame, said slide member being operatively associated with said rear swing frame so as to translate pivotal movement of said rear swing frame into longitudinal movement of said slide member and said shock assembly being operable to dampen pivotal movement of said rear swing frame relative to said main frame; a rear wheel operatively secured to said rear swing frame and being vertically movable therewith, said rear wheel defining a second rotational axis; wherein said rear swing frame is secured to said main frame for pivotal motion about said pivoting axis at a location that is vertically above a line extending between said first and second rotational axes. 15. The motorcycle assembly according to claim 14, wherein pivotal movement of said rear swing frame relative to said main frame causes said slide member to slidably move relative to said main frame against a biasing force of said damper. 16. The motorcycle assembly according to claim 15, wherein said shock assembly further comprises a link that extends between said rear swing frame and said slide member, said link forcing said slide member to slidably move relative to said main frame upon pivotal movement of said rear swing frame relative to said main frame. 17. The motorcycle assembly according to claim 16, wherein said link includes a forward end secured to said rear swing frame and a rearward end that is secured to said slide member. 18. The motorcycle assembly according to claim 17, wherein said link forward end is pivotally secured to said rear swing frame and said link rearward end is pivotally secured to said slide member. 19. The motorcycle assembly according to claim 17, wherein said link forward end is disposed relatively forward of the pivotal connection between said rear swing frame and said main frame. 20. The motorcycle assembly according to claim 19, wherein said link forward end is pivotally secured to said rear swing frame and said link rearward end is pivotally secured to said slide member.
