This paper proposes a simulation scenario in order to compare a proposed motorcycle model in cornering condition. The behaviours obtained by considering a linearized roll dynamic and a nonlinear roll dynamic have been investigated in order to evaluate their use in designing automatic stability controls of a motorcycle. The former model shows a linear dependency on the roll angle and the steer angle. The second model starts from the former and removes the linearization on the roll angle. The comparative analysis of the results shows how the proposed model is able to describe adequately the cornering dynamics for a suficiently large roll angles. These performances are suitable for designing a motorcycle active safety device controlling the lateral dynamic for preventing lateral falls.
