Of all companies, I think most would agree that Harley coming out with a production electric is the most unlikely. They are however making strides into territories some thought they never would have. The earliest example of this was the liquid cooled VROD and now based on that general design the Street models. Who knows what is being discussed in their board meetings, it is all speculation.
What can be guaranteed is that every vehicle company better begin to understand that electric vehicles are the future. There is no question in my opinion that, though it may take quite a while, fully electric vehicles will completely replace ICE vehicles. A company like Harley that has been around for over a hundred years has lasted so long for a reason. Of course an electric bike will turn off many of their hardcore die hard riders but lifelong Harley loyalists like my self and my father (who has been riding Harley's for over 40 years) actually love electric vehicles and we are not the only ones.
If Harley is making an electric it will surely have a certain look and feel that will be all "Harley" even though it is electric. Maybe it is just the shock and surprise of it all that will make people take a step back and say wow, Harley made and electric, let me check this out.
