An in-line, two-wheeled vehicle, with a torque generator operably secured thereto is disclosed. The torque generator generates a defined auxiliary torque about the point-of-contact of the steering wheel, and it is sized to balance the naturally occurring torques arising at slow speeds about the point-of-contact of the steering wheel, thereby improving the stability and control of the vehicle. In one disclosed embodiment, the vehicle is a stand-up riding board. In another disclosed embodiment, the vehicle is a cycle, such as a bicycle or the like. Torque generator structures such as using an elastic member, mechanical linkage, and dampening systems are also disclosed.

1. A two-wheeled vehicle for operating on a riding surface, said vehicle having: a frame tiltable about a longitudinal center line;a first wheel pivotally secured to said frame, said first wheel having a first area of contact with the riding surface;a second wheel pivotally secured to said frame, said second wheel having a second area of contact spaced apart from said first area of contact;a steering axis extending from said frame and intersecting said riding surface at a point, said point, first area of contact and second area of contact substantially aligned during steady-state straight movement of said vehicle;said first wheel pivotable about a shaft to define said steering axis to steer said two-wheeled vehicle by tilting said frame about said longitudinal center line; and,a torque generator operably engaging said shaft to apply an auxiliary torque about said steering axis during transient movement of said vehicle. 2. The two-wheeled vehicle of claim 1, where the amount of auxiliary torque generated by said torque generator substantially balances the natural occurring torques arising about said steering axis. 3. The two-wheeled vehicle of claim 2, wherein said torque generator substantially balances the natural occurring torques about said steering axis at slow operating speeds of the two-wheeled vehicle. 4. A two-wheeled vehicle for operating on a riding surface, said vehicle having: a frame tiltable about a longitudinal center line;a first wheel pivotally secured to said frame, said first wheel having a first area of contact with the riding surface;a second wheel pivotally secured to said frame, said second wheel having a second area of contact spaced apart from said first area of contact;a steering axis extending from said frame and intersecting said riding surface at a point, said point, first area of contact and second area of contact substantially aligned during steady-state straight movement of said vehicle;said first wheel pivotable about said steering axis to steer said two-wheeled vehicle by tilting said frame about said longitudinal center line;a torque generator operably engaging said first wheel to apply an auxiliary torque during transient movement of said vehicle; and,a computer system in communication with said torque generator and a sensor, and said computer system activated said torque generator only upon predetermined condition being detected by said sensor. 5. The two-wheeled vehicle of claim 4, wherein said sensor is a speed sensor, and said predetermined conditioned is the detected speed of the vehicle being below a predetermined level. 6. The two-wheeled vehicle of claim 2, wherein said torque generator is formed by an elastic element operably extending between said frame and said first wheel. 7. The two-wheeled vehicle of claim 2, wherein said torque generator is formed by a mechanical linkage operably engaging said shaft. 8. The two-wheeled vehicle of claim 2, wherein said torque generator is formed by a dampener operably engaging said shaft. 9. The two-wheeled vehicle of claim 1, wherein said first and said second wheels are secured to trucks, and said trucks are detachably secured to said frame. 10. The two-wheeled vehicle of claim 1, wherein the vehicle is ridden by riders having different weights, and the auxiliary torque generated by said torque generator is proportional to the weight of each rider. 11. The two-wheeled vehicle of claim 1, further including a brake for operably engaging the second wheel. 12. An in-line two-wheeled vehicle truck system for a riding board comprising: a front truck portion having a front wheel mounting portion, a frame portion, and a front wheel pivotally secured to said frame portion, said wheel pivotal about a shaft to define a steering axis;a torque generator operably secured to said shaft and operably engaging said front wheel to apply an auxiliary torque about said steering axis during transient movement of said front wheel;a rear truck portion having a rear wheel mounting portion, a rear frame portion, and a rear wheel pivotally secured to said rear frame portion; wherein,said front truck portion and said rear truck portion are detachably securable to a substantially planar member to define an in-line two wheeled vehicle. 13. The in-line two-wheeled vehicle truck system of claim 12, wherein said substantially planar member is an off-the-shelf skateboard board. 14. The in-line two-wheeled vehicle truck system of claim 12, further including a brake structure operably engaging said rear wheel. 15. The in-line two-wheeled vehicle truck system of claim 14, wherein said brake structure include a foot pedal portion positioned on the substantially planar member, said foot pedal portion operably secured to a braking structure so as to engage said brake by a user stepping on said foot pedal portion. 16. The in-line two-wheeled vehicle truck system of claim 12, wherein said torque generator includes a cam that operably engages a concave surface, and said concave surface is positioned so as to optimize the auxiliary torque generated. 17. A two-wheeled vehicle for operating on a riding surface, said vehicle having: a frame tiltable about a longitudinal center line;a first wheel pivotally secured to said frame, said first wheel having a first area of contact with the riding surface;a second wheel pivotally secured to said frame, said second wheel having a second area of contact spaced apart from said first area of contact;a steering axis extending from said frame and intersecting said riding surface at a point, said point, first area of contact and second area of contact substantially aligned during steady-state straight movement of said vehicle defining a neutral position;said first wheel pivotable about a shaft to define said steering axis to steer said two-wheeled vehicle by tilting said frame about said longitudinal center line;a dampener operably secured to said shaft so as to operably engage said first wheel to apply an auxiliary torque about said steering axis and to the first wheel by resisting movement of said first wheel about said steering axis. 18. The two-wheeled vehicle of claim 17, further including a biasing structure operably engaging said first wheel, said biasing structure biasing said first wheel to said neutral position. 19. The two-wheeled vehicle of claim 18, wherein said biasing structure is a spring. 20. The two-wheeled vehicle of claim 17, wherein said dampener is a pneumatic dampener in communication with a control system, and said dampener is activated on predetermined criteria detected by said control system.
