Hi Tim, I am from West Yorkshire, just outside Wakefield. I have ordered a DIN CanBus connector for my Optimate that I used on my Pan, hopefully it works okCongrats on the new purchase, you didn't say what part of the country. I'm in Windsor, Bahnstormer is my local dealer.
The BMW charger plugs into both sockets for trickle charging as do after market chargers.
If you're looking around for a new charger, I would love to find one that simultaneously charges the bike and has 2 USB ports for the helmets.
Let me know if you find anything.
