It looks like 3+4=7 is the warranty from Honda.
So this lifetime warranty, is likely a dealer thing. ie: have to bring it to the dealer for warranty service. Since we don't know the selling price / reserve, we don't know what the dealer is charging for that warranty (if at all).

is the dealers web page for this model. $23,990 is list price with a $3k discount currently offered. no mention of a lifetime warranty on the dealer web page.
The goldwing is the only motorcycle in the same class as the RSV/RSTD for reliability.
