While many previously published works examine motorcycle lateral stability through simulation, current literature incorporating the results of motorcycle lateral stability testing is rather limited. Further, the documented effects of a passenger on weave and wobble vibration modes
has not been published. While conventional wisdom in the public domain suggests that the addition of a passenger benefits weave mode, the effect of a passenger on wobble mode has received even less scrutiny. Unlike bicycles, the majority of motorcycles sold to consumers incorporate
accommodations for carrying a passenger. The current work presents the analysis of experimental weave and wobble stability test data collected with a rider and luggage, with and without a passenger on a touring motorcycle. The Stochastic Subspace Identification (SSI) method has been used to quantify weave mode content and further utilized to examine the wobble mode content. A brief review of the test and analysis protocols is presented followed by the results of
the analysis. For the motorcycle tested, the results confirm the stabilizing effect of passenger on weave mode and suggest little effect on the wobble mode. Although stochastic excitation has previously proven effective for weave identification its usage and limitations for wobble are examined.
