Lockup hydraulic valve system for controlling side swing arm supported wheels on a motorcycle when the wheels are in a downward ground engaging position. The valve system has an open-unlocked and closed-locked position. In the unlocked position, a driver riding the motorcycle about turns where the bike tilts either to the right or to the left allows the corresponding side wheel to move upward. Also in the unlocked position, the side wheels will raise when the motorcycle is running over uneven road surfaces. In the locked position, the side wheels stay in a rigid/fixed downward position while the motorcycle is standing still up to speeds of approximately 15 mph. Magnets attached to the front wheel along with a pickup sensor determine the speed of the motorcycle. Above, 15 mph, a relay activated safety switch overides the locked position putting the valve controls into the unlocked position. A handle bar mounted toggle switch with corresponding colored panel indicates to the driver the positions of the valve controls.
