Electric has caught up on range. A quick google search shows Zero Motorcycle claims 185 miles and Tesla is boasting 265 miles. Range hasn't been much of an issue for awhile.
Recharge time is the biggest difference in my opinion. Depending on your intended use of the vehicle, it's either a non issue or a deal breaker.
For a commuter - recharge once a week or so (depending on commute length) overnight and be done with it.
For a weekend warrior who just likes cruising and exploring - recharge during an hour ish lunch in some dinky town if you convince someone to let you borrow their outlet.
For a long distance rider - plan your route using the online maps like

For crazy riderrs like me - the recharge time is a deal breaker. Yes, I know it's been done, but that Zero was heavily modified.
Would I buy an electric? Absolutely!! My work has a charging station right in my parking lot. But would I get rid of my gas guzzling bike? Nope. I need the speed of a standard gas station for the rides I do.
