Battery charging

[Grumpy Goat]

Hi All Just bought a BMW r1250r sport 2021 model ,question is I have a optimate 5 charger , I know I can charge if I take the battery off the bike,
but can I charge the battery when it is on the bike , because of the electronics, do I need to get a special bmw charger, I have charged bikes in situ , with this trickle charger ,before,
Also is there a Charging point on this model,
Many thanks
Colin

There is no built-in charging point on this motorcycle (or any motorcycle I know of; if any, all are added by the dealer). No need to get a BMW charger.

I have a pigtail attached directly to my battery, enabling me to use my Deltran Battery Tender charger as / when needed, without removing the battery cover. My arrangement is shown below. The negative end of the pigtail will be attached to the terminal shown, while the positive end should be attached directly to the positive terminal (not shown; inboard end of the top of the battery) as opposed to the remote / aux. positive terminal. I have the free end clipped to the bracket for my rear brake reservoir.

   

Your Optimate 5 charger should have come with a fused pigtail (see on the right side of the Optimate photo below). I have had no issues with my setup over 52k miles / 6 years.
