Thank you for the tally, Shinysideup, and the cultural perspective, Roma256. That does suggest e-motorcycles are in the minority among two-wheelers.
As Roma256 mentioned, I think that there are lifestyle and population density differences that US e-motorcycle manufacturers need to overcome to increase their appeal to Europeans.
Even in the US, women riders I know prefer bikes with lower seat heights. My wife much prefers her Suzuki Boulevard maxi-scooter to any ICE sport or touring bike due to the seat height. On my Brammo Empulse R, she can sit comfortably with both feet touching the ground and enjoy riding, but cannot say the same for any pre-2014 Zero because she is shorter than I am. Also, for practical purposes, she prefers her scooter due to its built-in underseat storage. No stock e-motorcycle comes with storage.
I hypothesize that city-dwelling European men and women would prefer e-scooters to e-motorcycles for the following reasons:
* The reduced seat height, lower center of gravity, and non-aggressive styling of a scooter will appeal to women and men who might otherwise be too short for a motorcycle.
* The built-in storage is practical for running errands and carrying small loads safely for short distances such as groceries or parcels.
* The lower speeds of urban roads (ie. non-autobahn) don't require the muscle of a motorcycle.
* If the German laws for motorcycle licenses are any example, it looks like novice European motorcyclists over 16 years old may not ride anything with a motor larger than 125 cc or 11 kW (14 hp), so e-bicycles, e-mopeds, or e-scooters would be their easiest entry point. The spec page for Brammo's Enertia suggests that it is capable of 13 kW (17 hp) peak, so maybe novice riders might be able to squeak by with it. Even the 2015 Zero FX ZF2.8 offers no less than 20 kW (27 hp), and would require German motorcyclists to be over 18. My understanding is that to ride any motorcycle with motor more powerful than 25 kW (33 hp), you must first spend two years with the 25 kW-capped license.

I guess this brings us back to market penetration and brand recognition. A European customer would have to be EV savvy or lucky to happen across a Brammo or Zero while shopping in Europe.
