A traction control system for two and three wheeled motorcycles that prevents or limits the rear wheel(s) from slipping when the operator accelerates the vehicle. If the torque supplied by the motor exceeds the tractive force developed between the rear tire(s) and the road surface the rear tire(s) will slip creating a dangerous condition. The operator engages the system and selects the degree of desired traction control. The system detects rear (driven) and front (non-driven) wheel rotational speeds. If the rear wheel(s) begins rotating faster than the front wheel(s) the traction control computer will send a signal to the motor control unit to reduce the motor's power output. Additionally, as the operator applies the throttle the traction control computer sends a signal is sent to the rear suspension to stiffen for the purpose of more efficiently transmitting power to the rear wheel(s) and road surface.
