Abstract
A driving state display device of a straddle type vehicle has a nonvolatile memory in which operation modes are stored to be readable with a grade point provided for each operation mode, the grade point being proportional to a degree of energy-saving operation or uneconomic operation. A microcomputer calculates the rotational speed and acceleration of an engine to determine the operation mode of the vehicle. The grade point corresponding to the operation mode is read from the nonvolatile memory and accumulated until a predetermined time period has elapsed, after which it is determined whether the accumulated value falls in an energy-saving operation range or an uneconomic operation range without the use of a fuel flow meter or the like, said determined result communicated to a rider of the vehicle via a display.
