The present invention achieves improvement of the color reproducibility, color rendering properties and light emitting efficiency of a white light emitting diode. The motorcycle restraint device comprises a base assembly, a catch assembly and a catch pin assembly. The method simultaneously controls the torque transfer across each clutch by linearly decreasing the torque transferred across the off-going clutch while linearly increasing the torque transferred across the on-coming clutch in an inversely proportional rate. Furthermore, there is a process as per the invention for determining the value of at least one parameter of the cross-sectional profile of the gripping tire.
