2013 Honda F6B unveiled

That is not a custom. The F6B (as in Bagger) is Honda's new Gold Wing based tourer but instead of the household that is the regular Gold Wing, this is more of a trailer.
It looks interesting from its short screen to the swept back bags - even slightly Victory Vision like from the back. But it does lose the top box in the process. The engine is the same 1832cc flat six, all butter and cream in smoothness plus all the electro-luxuries - ABS, MP3, reverse gear etc.
The bike is 28kg lighter though, so it should be just as smooth but a wee but quicker. Note clever use of the word wee and Gold Wing in the same sentence.
