A transparent fuel tank for a motorcycle in which the state of wiring and piping under the fuel tank can be inspected. Therefore, the distortions of the motor voltage and current and the torque ripple of the motor are improved by using the dead band compensation for estimating the voltage distortion on the basis of a model current generated from a current command value such that no feeling of physical disorder is given in the handle operation of an electric power steering apparatus. Active pillars are arranged between corresponding even and odd stacks of conductive strips.
