One of the few things you pick up with the current top box if you get the "Fully Equipped" version it will lock and unlock with the central power locks if your bike is so equipped, will have an interior light and can have a third brake light mounted to the top box if you want to spend even more.

It is probably difficult to justify the $1,700 for the current "Fully Equipped" top box if you already have a paid for version from a previous model but these features are what you get with the new version. This is not an case for the new version, just pointing out the differences.
