So, if under the same throttle %, is it safe to say that the miles achieved by a 100hp moto would be the same as a 200 hp, if the 100 hp is not working out of it's normal working range?

It is about efficiency, not % of throttle. Mechanical power out / electrical power in. If the two motors are approximately the same efficiency at the comparison power level then the range would be close, probably even difficult see the difference. There are however other considerations and the added weight of the heavier motor will slightly lower the overall efficiency. The heavier motor could want lower voltage and higher current in order to obtain the same power level. This could require heavier cables. There will almost certainly be a change in drive ratio. You can think of the differential as consuming ~5% of the motor power and a transmission about 10%. If your new motor allowed you to get rid of the transmission that would be a pretty big win on overall drive train efficiency including the space reclaimed by the transmission and the weight of said component.

Thanks!

The comparison isn't about throttle %.

For the same vehicle speeds, hence same motor output (assuming the smaller motor has ballast to bring it to the same weight as the larger to make the comparison easier), different motors will have different efficiencies according to their design and construction.

Where can I start researching about that particular topic, more efficient engine design etc for the electric side?
