Energica was built more as a race bike, hence the chain. The AC could be better, but show a car that has decent AC charging? yah, they don't because everything mainstream is geared for the DC fast charge like the bike already is, and the rest are not.
300 miles, shit.. im bitching after 80 to 100 miles. That's a long ride, your hands are sore, arms sore, ass sore, im ready for a stretch and or a beer. In all honesty, that is what I tell people, ok so it takes you 40 minutes to recharge? Have you ever ridden with a pack of Harley Tards? 40 minutes is about par just to get gas on a good day! By the time everyone gets their drinks, smokes a cigarette, fills the bikes, sure enough you are getting ready to pull out and. waah, so and so's cow has to pee now, another 10 minutes shot. If you are doing a poker run, now make that more like an hour to hour and a half. Your bike is NOT going to be at 9 percent either, it's probably going to be like maybe 68 percent on a longer run, so you don't even need a full charge /full charge time. I think one of the reasons they limit it to 15 amps, besides obviously that's the rating of the charger, but, it can take 115 volt too, and 15 A is your standard circuit, without having to do special wire and bigger breakers now. That way they can claim it's 115 volt compatible too, w/o having to hear complaints because someone keeps popping the breaker because they have it set too high.
Even racing, 15 minutes is about an average run. If you are pushing longer than that, you are getting tired, getting sore, probably starting to make mistakes. Granted you travelled 25 to 30 miles in that 15 but still, it's not hours and hours of driving.
