sway means for controllably moving said motorcycle mount assembly between the left and right sides of said support structure;

surge means for controllably moving said motorcycle mount assembly between the front and rear ends of said support structure;

roll means for controllably moving the motorcycle frame from a vertical position to inclined positions on the left or right side of said vertical position;

yaw means for controllably pivoting the motorcycle mount assembly to provide horizontal rotation of said motorcycle frame relative to said support structure;

front fork elevator means for controllably lowering and raising the front end of said motorcycle frame;

rear fork elevator means for controllably lowering and raising the rear end of said motorcycle frame independently of said front fork elevator means wherein said sway means, surge means, roll means, yaw means, front fork elevator means and rear fork elevator means can be controlled to provide movement of said motorcycle frame with six degrees of freedom to thereby provide a realistic simulation of riding a motorcycle.

2. A motorcycle simulator according to claim 1 wherein said motorcycle mount assembly includes a mounting tower assembly comprising:

a base attached to said support structure;

a tower having a bottom connected to said base and a top;

at least one vertical guide rail attached to said tower; and

means for pivotably attaching said motorcycle frame to said vertical guide rail(s) wherein said motorcycle frame can travel vertically and pivot for and aft from the tower bottom to the tower top while remaining securely attached to said mounting tower assembly.

3. A motorcycle simulator according to claim 2 wherein said motorcycle main frame includes a front down tube assembly, a rear tube assembly, a top backbone tube assembly and a bottom tube assembly and wherein said main frame is attached to said vertical guide rails at said rear tube and backbone tube assemblies.

4. A motorcycle simulator according to claim 2. wherein said surge means comprises:

at least one surge guide rail extending from the support structure front to the support structure back; and

means for attaching said motorcycle mount assembly to said surge guide rail(s) to provide controlled movement of said motorcycle mount assembly along said surge rail(s).

5. A motorcycle simulator according to claim 4 wherein said means for attaching said motorcycle mount assembly to said surge guide rails comprises:

a surge sled having a front end, a rear end, a left side, a right side, a bottom and a top;

means for slidably attaching the bottom of the surge sled to the surge guide rail(s) to provide fore and aft movement of said surge sled;

at least one sway guide rail attached to the top of said surge sled and extending from the left side of said surge sled to the right side of said surge sled; and

a sway sled having a front end, a rear end, a left side, a right side, a bottom and a top;

means for slidably attaching the bottom of the sway sled o the sway guide rail(s) to provide side to side movement of said sway sled; and

means for attaching said motorcycle mount assembly to the top of said sway sled.

6. A motorcycle simulator according to claim 5 wherein said sway means comprises said sway guide rail(s), said sway sled and said means for slidably attaching the bottom of the sway sled to the sway guide rail(s).

7. A motorcycle simulator according to claim 5 wherein said means for attaching said motorcycle mount assembly to the top of said sway sled comprises said roll means and said yaw means.

8. A motorcycle simulator according to claim 7 wherein said yaw means comprises:

a pivot plate attached to the base of said motorcycle mount assembly; and

horizontal rotation means for connecting said pivot plate to said sway sled and for providing controllable horizontal rotation of said pivot plate relative to said sway sled.

9. A motorcycle simulator according to claim 8 wherein said roll means comprises:

a roll plate attached directly to the base of said motorcycle mount assembly; and

vertical rotation means for connecting said pivot plate to the base of said motorcycle mount assembly and for providing controllable vertical rotation of said motorcycle frame from a vertical position to inclined positions on the left or right side of said vertical position.

10. A motorcycle simulator according to claim 9 wherein said front fork elevator means comprises:

at least one front fork cylinder having a bottom end and a top end;

at least one front fork piston having a lower end housed within the top end of said front fork cylinder and an upper end attached to said motorcycle frame wherein said fork piston(s) is(are) movable between a retracted position within said front fork cylinder(s) and an extended position; and

means for controllably moving said front fork piston(s) between said retracted and extended positions to thereby provide lowering and raising of the front end of said motorcycle frame.

11. A motorcycle simulator according to claim 10 wherein said rear fork elevator means comprises:

at least one rear fork cylinder having a bottom end and a top;

at least one rear fork piston having a lower end housed within the top end of said rear fork cylinder and an upper end attached to said motorcycle frame wherein said rear fork piston(s) is(are) movable between a retracted position within said rear fork cylinder(s) and an extended position; and

means for controllably moving said rear fork piston(s) between said retracted and extended positions to thereby provide lowering and raising of the rear end of said motorcycle frame.

12. A motorcycle simulator according to claim 10 which further includes a front axle and wherein the bottom of said front fork cylinder(s) is connected to said front axle.

13. A motorcycle simulator according to claim 11 wherein said rear fork assembly comprises a swing arm having a rear end, a lower arm extending forward from said rear end and an upper arm extending forward from said rear end and wherein said upper arm is connected to the bottom end of said rear fork cylinder(s) and said lower arm is connected to said motorcycle frame.

14. A motorcycle simulator according to claim 1 wherein said roll means and yaw means are hydraulically, pneumatically or electro-mechanically controlled.
