Saturation is "soft" but if you plot V & I without suppressed zeros on both axes it's not as soft as it appears here. Th Honda and KTM curves are close enough to identical eg he gets about 13A at 3000 RPM and under 15A at 9000 RPM. ie for practical purposes saturation is about 13A. (4th box down labelled "Estimated stator parameters based on DC output".) The XR having 10 stator poles equipped but only 4 wound is the "magic bullet" for the Honda. This just means that the designers purposefully chose to limit the power to about 40% of what is sensibly available and he has increased the available power by using all the steel.
