since April fools day is still months away, this must be legit. A 1975 Honda no one ever wanted to ride enough to remove from it's factory shipping crate

but when the 360-series bike came out in 1974, the shipping crates Honda used were not the meteal erector-set style seen here, they were made of wood, and some assembly of the bike was necessary

Indeed, reading the article from Hagerty shows that this was apparently stored in the open air at a New Orleans, Louisiana dealership
