Mine came with copper L brackets to make room for the 07 K1200 LT cables. The battery si a bit smaller and you may need to find a small piece of wood to put underneath it so the battery tie down fits. That was all I did, and its been there for almost 2 years.
You might want to talk to the folks where you are getting the battery from and make sure it still ships with hit. I ordered mine on a web page and order the copper offsets with it. They called me the next day to make sure I knew the battery came with a pair and took the extras right off the order.
The good things are that you will never see acid spills and the BMW charger seem to like it every bit as much as it did the Gel battery that came with the bike.
