Swingarm, as a mechanical element, has a significant influence on overall motorcycle dynamics. Dynamics is especially influenced by stiffness, which must be at an appropriate level to provide response and stability, and also transfer vertical, lateral and torsional loads. CFRP (Carbon Fiber Reinforced Plastics) allows us to reduce weight due to high stiffness-to-weight ratio. This paper presents experimental measurement results of torsional and vertical stiffness distribution over a CFRP single side swingarm prototype. The TRITOP optical measuring system was chosen for data collection, as it allows fast and precise measurement of reference points displacement in 3D space. Several static loading conditions were then measured while loading was applied using weights on a testing jig. The results were plotted as distribution of stiffness over length to show weak spots. The gathered data will be used for numerical simulation and further layup and stiffness optimization.
