1. An all terrain vehicle (ATV), comprising: a vehicle frame;a seat pivotally mounted relative to the frame at a pivot position adjacent a front of the seat;a seat load compensation assembly comprising a load frame which is pivotally mounted relative to the vehicle frame and connected to a rear port
1. An all terrain vehicle (ATV), comprising: a vehicle frame;a seat pivotally mounted relative to the frame at a pivot position adjacent a front of the seat;a seat load compensation assembly comprising a load frame which is pivotally mounted relative to the vehicle frame and connected to a rear portion of the seat, the seat load compensation assembly providing a reactive force on the seat; anda seat height adjusting mechanism, whereby the seat may be inclined about the pivot position relative to the vehicle frame and held at a different inclined height by way of the seat height adjusting mechanism;wherein the reactive force on the seat may be modified for different drivers. 2. The ATV of claim 1, wherein a rear portion of the load frame is pivotally mounted to the vehicle frame, the rear portion of the load frame extending forwardly towards the seat. 3. The ATV of claim 2, wherein the seat height adjusting mechanism comprises a latching jaw which cooperates with latching elements. 4. The ATV of claim 3, wherein the seat height adjusting mechanism cooperates with the seat load compensation assembly in order to vary one or both of, the seat height and the reactive load on the seat. 5. The ATV of claim 4, wherein the seat and the load frame intersect at the seat height adjusting mechanism. 6. The ATV of claim 5, wherein the seat height adjusting mechanism comprises a latching jaw, and the load frame comprises latching elements. 7. The ATV of claim 6, wherein the latching jaw is in the form of a pawl. 8. The ATV of claim 6, wherein the latching elements are located in a plate mounted relative to the vehicle frame. 9. The ATV of claim 8, wherein the seat height adjusting mechanism comprises a plurality of latching jaws connected to a lever, where the lever moves the latching jaws out of a latched position. 10. The ATV of claim 9, wherein the latching elements are located in the plate, and the plate is mounted to a front of the load frame. 11. The ATV of claim 6, wherein the seat load compensation assembly comprises one of a coil spring or damper, positioned between the vehicle frame and the load frame. 12. The ATV of claim 11, wherein the seat load compensation assembly comprises a spring load adjustment mechanism. 13. The ATV of claim 12, wherein the latching jaw is connected to a lever positioned adjacent to a rear of the seat. 14. The ATV of claim 13, further comprising a rear utility rack mounted rearward of the seat, the utility rack being positioned above and substantially covering the load frame, and the lever and the spring load adjustment mechanism being accessible with the utility rack in place. 15. An all terrain vehicle (ATV), comprising: a vehicle frame;a seat pivotally mounted relative to the frame at a pivot position adjacent a front of the seat; anda seat load compensation assembly comprising a load frame which is pivotally coupled to the vehicle frame and coupled to the seat to provide a reactive force on the seat;wherein the reactive force on the seat may be modified for different drivers. 16. The ATV of claim 15, wherein a rear portion of the load frame is pivotally mounted to the vehicle frame, the rear portion of the load frame extending forwardly towards the seat. 17. The ATV of claim 16, further comprising a seat height adjusting mechanism, whereby the seat may be inclined about the pivot position relative to the vehicle frame and held at a different inclined height by way of the seat height adjusting mechanism. 18. The ATV of claim 17, wherein the seat height adjusting mechanism comprises a latching jaw which cooperates with latching elements. 19. The ATV of claim 18, wherein the seat height adjusting mechanism cooperates with the seat load compensation assembly in order to vary one or both of, the seat height and the reactive load on the seat. 20. The ATV of claim 19, wherein the seat and the load frame intersect at the seat height adjusting mechanism. 21. The ATV of claim 20, wherein the seat height adjusting mechanism comprises a latching jaw and the load frame comprises latching elements. 22. The ATV of claim 21, wherein the latching jaw is in the form of a pawl. 23. The ATV of claim 21, wherein the latching elements are located in a plate mounted relative to the vehicle frame. 24. The ATV of claim 23, wherein the seat height adjusting mechanism comprises a plurality of latching jaws connected to a lever, where the lever moves the latching jaws out of a latched position. 25. The ATV of claim 24, wherein the latching elements are located in the plate, and the plate is mounted to a front of the load frame. 26. The ATV of claim 21, wherein the seat load compensation assembly comprises one of a coil spring or damper, positioned between the vehicle frame and the load frame. 27. The ATV of claim 26, wherein the seat load compensation assembly comprises a spring load adjustment mechanism. 28. The ATV of claim 27, wherein the latching jaw is connected to a lever positioned adjacent to a rear of the seat. 29. The ATV of claim 28, further comprising a rear utility rack mounted rearward of the seat, the utility rack being positioned above and substantially covering the load frame, and the lever and the spring load adjustment mechanism being accessible with the utility rack in place.
