The R1 features Yamaha D-MODE (or drive mode) with rider-selectable throttle control maps to program YCC-T performance characteristics for riding conditions.

The change of throttle aperture effect little on atomizer flux through experiment on flux characteristics. The flux was effect by the diameter of mix chamber.

This paper describes an approach using power bond graph and condition space method to digitally imitate the dynamic characteristics of the hydrostatic bearings with film feedback throttle.
