Measurement of Motorcycle Riders Eye Locations 856131
In this study, with a final objective of obtaining such data
necessary for the international standardization of eye ranges of
motorcycle riders in the future, we selected five different models
of motorcycles (with engine capacities ranging from 250 cc class to
1,000 cc class) comprising four typical motorcycle types and
measured the eye locations and riding positions of 456 Japanese and
American motorcycle riders mounted on those motorcycles.
As a result, we found that when the shoulder location is adopted
as the origin, four items-namely, distances between shoulder and
handle grip, shoulder and hip, shoulder and eye, and the angle
formed by the locations of eye, shoulder, and hip-are nearly
constant, regardless of differences in vehicle frame dimensions.
Therefore, the eye range of motorcycle riders can be located from
the relative positions between the handle grip and hip point.
Furthermore, through comparison of anthropometric data between
Europeans and Americans, the actually measured eye locations of
American riders can be used as representing European riders'
