I always thought that there was a decent market for an electric jet ski (something Polaris knows about). Many reservoirs and public fresh water lakes prohibit IC powered craft from using their facilities due to pollution and noise concerns. But you would think that electric power would be permitted.
Also, the same goes for snowmobiles, which are being prohibited in many areas, again due to pollution. However, the power requirements for those things might put a strain on the technology right now.
I am pretty sure that Polaris is going to use electric power in a number of their products in the future. But will it be motorcycles? I am not so sure, with with sales of electric motorcycles being so low right now. Plus, the 10% tax credit is gone and unlikely to return, what with the Republicans running Congress and likely not showing any love for anything manufactured anywhere on the West Coast.
Even some states are backing off on EV rebates.
Both of these trends will likely do little to improve the public's acceptance of electric vehicles - no matter what the big car companies and government are hoping will happen.
