I have been a good OEM after market customer. I even bought a new BMW battery the other day (before the dealer told me that the tender was bad).

After paying mega bucks for clothes and pieces, you'd think they would at least do something....
I guess I'll just go the traditional tender wired straight to battery. I'm not paying the cash for unit that doesn't hold up. I must not be the exception, because I have looked on Ebay and seen some for sale as "no longer works. For parts only."

I may write the head of BMW Motorrad USA to let him know how I feel. Probably a waste of time. After being such a fan, and a Harley convert for over six years, this plain stinks.

Please let me know if I need to use a CAN BUS tender and should not use a regular one that is straight wired. The OEM looks cool, but I want one that lasts!


Writing BMW IS a waste of your time..
If you have a spare plug port on your bike go get the BMW socket and wire it directly to the battery. Easy, looks factory, and is just plain better than worrying about when the canbus shuts the power off to the (stock) sockets. Put the battery tender on it whenever you want. If you don't have a spare plug port you can still get the plug (check out "Powerlet") and mount it wherever you a panel, on a bracket...wherever..
