Not surprisingly, the Optimate 4 Can Bus edition is proving most popular.
Currently available from BikespeedUK for £56.95, OptiMate 4 CAN BUS BMW Motorcycle Battery Charger (bikespeeduk.com)

If you would like to be thrifty and happy to bolt a pigtail lead to the battery (or use croc. clips),  then for £15 you can have this offering from Halfords,

Then again, if the charger must have BMW on it, Nippy Normans will happily take £139 off you for this,

I looked into solar power but you need to spend big for a decent result.The Optimate DC-DC is/was the most sensible answer for me.

One thing that the poll does show is that there are plenty of alternatives to an Optimate 4 Can Bus edition, charging via the onboard socket.

Some new R1250RT's won't accept a charge via the onboard socket, keep it simple and go directly to the battery.

As far as I know the 2021 RT works fine from the fairing aux socket, not from the rear one. Mine charges fine through the front aux socket. No need for direct battery connections.

Found this on BMWLT.

"I use an Optimate 4 through the aux socket on the fairing and it works fine. The one near the pillion seat doesn't seem to work for charging."

This problem was with a BMW charger!

Yes, I have tried the rear socket - doesn't work. Optimate 4 charger. Front one is fine. I have seen other comments reporting the same issue.

Well, there you go then, confirmation that the onboard socket charging problem is bike specific not down to which charger is being used, BMW or Optimate 4 Can Bus.
