| Summary: | The aerodynamic drag of a motorcycle greatly affects its energy efficiency, with the rider’s posture being a key factor in determining overall drag. This study presents a systematic comparative analysis of various rider postures through a multi-phase experimental approach: modification of an electric motorcycle for a reclining rider posture, quantitatively measuring rider–vehicle interaction forces and developing an analytical framework that correlates rider posture with ergonomic factors and aerodynamic parameters.The results show that aerodynamic drag can be reduced by up to 56% by changes to rider posture but viable applications are limited by the associated trade-offs, in particular a reduction in rider–ground interaction forces of up to 60%. Through this analysis, critical design constraints are identified and quantitative relationships between rider positioning, aerodynamic efficiency, ergonomic constraints and operational stability are established. The findings offer evidence-based design guidelines for optimising the balance between aerodynamic performance, rider control, and ergonomic considerations in motorcycle design. |
