FYI, I have two of the Elcons (not for sale) that I can carry in the side bags on my 2017 SR. My bike also has a charge tank. On a recent trip (from the Bay Area, CA, US, to Reno NV, US) I was able to charge -- using two J1772 plugs -- at 1C. One thing I learned: while most Chargepoint stations would let me use two plugs (I used my card for one, and my cell phone for the other), a couple would only let me use one plug, no matter what I tried.
Also, after a bit of experimenting, you can put both the elcons *and* the wiring harnesses in the side cases.
I purchased a couple of new Elcon PFC 2500's direct from Elcon in Sacramento a couple of weeks ago. For $700.00 each. All programed for a Zero, but not the correct cables. So I made my own adapters. I wired up two 50 amp Anderson connectors each with a with 25 amp blade fuse direct to the motor controller battery terminals. At home, I can charge at 8KW (using two Zero quick chargers as well), but only 6.3 KW while on the road. I have plenty of storage space as I also have a tank bag, travel trunk and I often carry a backpack as well, so the cables are no issue and don't take up much room anyway.
I have the Pwr Tank, so no charge tank.
BTW, I am from the SF Bay Area and I used to work (34 years) for the CC of SF. Now retired for five years. And I was born in SF.
Next time you're headed for Auburn, CA or Reno, NV or even Sacramento, let me know if you would like to meet up. But I have been trying to avoid the SF Bay area as much as possible in the last few years.
