Either two or three years ago - I am pretty sure it was either April or May, 2013 - some very senior Yamaha engineers told me they would love to be able to marry an electric motor to their machines; according to them range and power draw were the limiting concerns. Sounds to me like EV skeptics everywhere. To be more clear, these were long-time old-timers: i.e., they have spent their entire careers perfecting ICEs for go-fasts, and likely aren't of the right mindset to embrace electric motors. Regardless, what they believe carries weight.
Sound familiar?
