- Many motorcycle crashes involve the motorcycle capsizing and sliding on the road surface. Often, when performing speed calculations, the reconstructionist will need to calculate the energy or speed loss for the capsizing and sliding phase. To perform these calculations, the reconstructionist would determine the slide distance based on the physical evidence, and then a range of decelerations for the slide would be selected from physical tests reported in the literature for motorcycles with similar characteristics sliding on similar surfaces. This approach is adequate in many instances but sometimes results in a wide range due to the variability in reported decelerations in prior studies. It could be helpful to narrow the range of decelerations that need to be used. However, most of the past studies described their tests with inadequate detail to parse out precisely what factors were most influential in the producing the reported decelerations. The present study reports additional motorcycle sliding tests, attempting in the process to lay out a model of how future tests could be reported such that influential factors could be identified.
