I don't know... my 2019 Yamaha XMAX gets 70 mpg on the highway and only requires about 3.3 gallons of fuel, so that's over 200 miles on a three minute gas station stop. Electrics are a LONG way from that. Until then, 6kW charging at a shopping mall is fine... it may take an hour for the bike to go another sixty miles BUT I have something to do to kill the time at the mall. If I take in a movie, I can even get a 100% charge. Not a bad deal for a leisurely joy ride. For us "40 hour a week" guys, I don't REALLY need more than Level 1 charging because I'm going to be sitting at my desk for eight hours anyway.
When the weather warms up again in the Spring I'm already connecting the dots for an "Around Long Island" ride on my Zero. There are enough Level2 statoins around to make that possible. Most of them are in shopping malls; the one on Shelter Island is at a police station so I need to see what is in the area to kill time there.
Right now, electric motorcycles are simply not practical as "only bikes" unless you are really really dedicated and willing to make compromises. As I've pointed out before, though, for over 90% of the riding I actually do, the Zero is perfectly capable and it save a lot of wear and tear on my ICE bikes to boot.
