With the 100 hp setting (green curve with maximum power restricted to 100 hp), throttle valve aperture is significantly attenuated, and rotating the throttle grip fully (100%) does not achieve full throttle valve aperture (throttle valves reach a maximum angle of less than 90°. However, this setting still allows the maximum throttle valve opening to be attained when the throttle grip is fully rotated (100% throttle grip rotation corresponds to a throttle valve opening angle α equal to 90°). Therefore, a given aperture angle of the throttle grip corresponds to a lower throttle valve aperture angle. With the 150 hp Soft setting (purple curve with maximum power of 150 hp available), throttle valve opening is “softer“. This linear relationship, however, does not apply at small throttle grip aperture angled (a small throttle valve aperture angle is achieved with a slightly higher throttle grip rotation angle). Therefore, high throttle grip aperture angles correspond to identical high throttle valve aperture angles. With the 150 hp Hard setting selected (red curve with maximum power of 150 hp available), with the exception of the initial zone, the relationship between percentage throttle grip aperture and percentage throttle valve aperture is practically linear (direct). On a conventional mechanical system there is only one throttle valve aperture regimen, which is determined by the profile of the control roller mounted on the spindle of the valves themselves and actuated by a metal cable that moves as the throttle grip is twisted. Each one of these is activated by the rider in relation to the selected riding mode. ![]() Different curves for different engine speed bands are stored in the engine control unit. The three curves show the relationship between the throttle valve aperture regimens and the angle of the throttle grip.
