From my experience many former Harley owners that still want to ride and have fun, have opted for lighter weight dual sport motorcycles. They're light, they won't crush you if the bike falls over in the garage, this one below gets 72 miles per gallon, and they go just about anywhere, on or off road.
No need to electric when one can get dual sports such as the Yamaha XT-250, which is street legal and gets about 70 miles per gallon. Reliability? They've been making basically the same bike for 30 years. They run forever. Pretty much bullet proof. And these models come with a real low seat, electric start and provide large ground clearance for off road trails.
They're not for the Interstate, but around town or country roads, the fun and reliability are hard to beat.

I’m into dual sport bikes too, but my 1200 cc Buell that I mentioned a few comments back is 440 pounds curb weight and not pig in the garage at all. I did replace the OEM muffler as it was a boat anchor and put in li battery, too (nod to the rare earths crowd).
