Equations of Longitudinal Motion for the Rider/Motorcycle System

Longitudinal equations of motion for the rider/motorcycle system are deduced. The rider's body is assumed to be composed of lower and upper leg, pelvis part, torso, head, lower and upper arms. The motorcycle is composed of front wheel with suspension, rear wheel and motorcycle frame.

Equations of motion are obtained for each part. The actions and reactions working at the joints or connecting points are considered.
