Dimensional incompatibility between rider and motorcycle is one of the most causative factors responsible for the prevalence of musculoskeletal discomfort among motorcyclists. The present study aims to identify the comfortable riding posture (CRP) and optimum riding position (ORP) for improving motorcycle design for better riding experience. The data (through image processing technique) was acquired from 120 Indian male motorcyclists (aged 19–40 years) using a static simulator test-rig. The CRP was achieved by adjusting three controls (handgrip, seat, and footrest of the test-rig), and perceived comfort and discomfort ratings. Weighed mean comfort joint angles of ten body-joints defining CRP were estimated and compared with the earlier studies. The best possible ORP among the nine test conditions (defined by the positions of the three controls) was estimated using Taguchi DOE. The study outcomes will help automobile designers to conceptualize the comfortable standard motorcycles.

骑手和摩托车之间的尺寸不兼容是造成摩托车手肌肉骨骼不适普遍发生的最主要原因。本研究旨在确定舒适的骑行姿势（CRP）和最佳骑行姿势（ORP），以改善摩托车设计以获得更好的骑行体验。数据（通过图像处理技术）是使用静态模拟器测试台从120位印度男性摩托车手（年龄19至40岁）中获取的。通过调整三个控制项（测试装置的手柄，座椅和脚凳）以及感知到的舒适度和不舒适度来实现CRP。估计了定义CRP的十个人体关节的加权平均舒适关节角度，并将其与早期研究进行了比较。使用田口DOE估算了九种测试条件（由三个控件的位置定义）中可能的最佳ORP。研究结果将帮助汽车设计人员将舒适的标准摩托车概念化。
