You're welcome, Mike.
I look forward to hearing Mike Bratcher's viewpoints on this subject.
I think the brace for the battery box strengthens the left side of the XR650L subframe.
However, the battery box weighs over ten pounds, and I don't think the subframe benefits from having the battery box slamming on it.
I have read reports of a few battery boxes breaking off during long trips into rough terrain.
I'm glad I removed the battery box when I relocated my Shorai battery to the top of the airbox.
However, one can remove 5 pounds of weight from the battery box by merely substituting a Shorai battery for the stock battery.
