Apologies for being a novice on the BMW side of things (I have only owned one since August).

I have a basic Optimate which I use over the winter to charge my old Kawasaki, am I OK using this on the RS or do I need a BMW charger to not upset the electronics? - and should I remove the battery from the bike?

On another point I am thinking of getting some engine protection bars, which is recommended?

Thanks

Wire an Optimate pigtail to the battery and you'll be fine. The only time you need a canbus specific charger is if you want to charge via the accessory socket.

I have a fused SAE pigtail (i.e., flying lead in Brit-talk) connected to my battery. During the winter, the bike (just like the car) is continuously connected to an Accumate or CTEK trickle charger. I've had no issues in several decades.

This is good to know, as I'm approaching my first winter as a BMW owner and had thought I was going to have no option but to cough up for a fancy BMW charger to replace my existing non-BMW smart charger.

So, if I fit an SAE flying piglead tail to my battery, does the bespoke BMW canbus charger actually offer any benefit over a non-BMW model?

No. But it does lighten your wallet.

Thank You, I will sort out the connection lead. That leaves a bit more cash to spend on engine protection bars :)

But, But, you'll another piece of genuine "BMW" equipment that was made by some battery charger manufacturer. I've seen BMW chargers that were identical to Battery Tenders, C-Teks, etc...

Buy a good charger at the best price and use the SAE lead. If you ever need heated clothing, you'll already have the accessory plug installed.

After all that I discovered a much better way to keep the battery and the bike charged up....... riding it our winter weather has been so mild I was out at least twice a month since December.

Off for a nice 260 mile round trip to Shropshire and back this Saturday, that will get the new front tyre bedded in.
