Motorcycle conversion assembly

1. A motorcycle conversion assembly, comprising:

first and second side members disposed in a laterally spaced-apart relationship;

first and second cross members operably connected to the first and second side members to thereby define a rigid frame;

first and second frame plates operably connected to the frame;

first and second axle plates operably coupled to and rotatably adjustable with the first and second frame plates; and

first and second torsion adjusting assemblies operably connected to first and second axle plates.

2. A motorcycle conversion assembly as set forth in claim 1 , wherein said second cross member is a rear cross member having an accessory plate operably coupled thereto.

3. A motorcycle conversion assembly as set forth in claim 2 , wherein said accessory plate further comprises apertures for mounting accessories.

4. A motorcycle conversion assembly as set forth in claim 2 , wherein said accessory plate further comprises supports for operably coupling the accessory plate to a motorcycle frame.

5. A motorcycle conversion assembly as set forth in claim 1 , wherein said torsion adjusting assemblies comprise a flange and a spacer operably connected to the first and second axle plates.

6. A motorcycle conversion assembly as set forth in claim 5 , wherein said torsion adjusting assemblies are adjustable relative to the spacer.

7. A motorcycle conversion assembly as set forth in claim 5 , wherein said first and second torsion adjusting assemblies are also operably connected to said first and second frame plates.

8. A motorcycle conversion assembly as set forth in claim 1 , wherein said first and second axle plates are rotatably adjusted relative to the first and second mounting plates by loosening one or more fasteners connecting the first and second axle plates to the first and second mounting plates and rotating either the first and second axle plates or the first and second mounting plates relative to each other.

9. A motorcycle conversion assembly as set forth in claim 1 , wherein said first and second axle plates are independently adjustable relative to each other.

10. A motorcycle conversion assembly as set forth in claim 1 , wherein said first and second torsion adjusting assemblies are independently adjustable relative to each other.

11. A motorcycle conversion assembly, comprising:

first and second side members disposed in a laterally spaced-apart relationship;

first and second cross members operably connected to the first and second side members to thereby define a rigid frame;

first and second axle plates operably coupled to and rotatably adjustable with the rigid frame; and

first and second torsion adjusting assemblies operably connected to the first and second mounting plates.

12. A motorcycle conversion assembly as set forth in claim 11 , wherein said first and second torsion adjusting assemblies are independently adjustable relative to each other.

13. A motorcycle conversion assembly as set forth in claim 12 , wherein said torsion adjusting assemblies are also operably connected to a first frame plate and a second frame plate.

14. A motorcycle conversion assembly as set forth in claim 13 , wherein said torsion adjusting assemblies comprise mechanical fastener assemblies that can be adjusted to control torsion and is operably coupled to the rigid frame.

15. A method of making a motorcycle conversion assembly, comprising:

providing first and second side members;

providing first and second cross members;

operably connecting first and second side members to the first and second cross members to thereby define a rigid frame;

providing first and second frame plates;

operably connecting first and second frame plates to the frame;

providing first and second axle plates;

operably coupling first and second axle plates to the first and second mounting plates in rotatably adjustable relationship;

providing first and second torsion adjusting assemblies; and

operably connecting first and second torsion adjusting assemblies to the first and second axle plates.
