There is alot of info on the bike ...it just happens to be inside the heads of many of our members.....not alot written down.
Some of it unsubstanciated rumors, but still fun to use anyway. Like that the 750 motor was first developed for use in Kawasakis "jet-ski", but the idea was scrapped. As they still had done a bit of work on the motor desgin, they changed it to be used in a street bike.
Also, many are not aware that the Vulcan 750 was assembled here in the United States, In Lincoln NE. Parts were shipped here from Japan along with the motor and frame. The plant also assembled some of the companys dirtbikes.
I am not sure how soon this started. I was always under the impression that : the first model...the VN700...was imported. In hopes of getting by the American imposed tarriff on bikes with motors over 700cc's, they opened the plant in Lincoln to start assembling the 750 and a few larger bikes...but the tarriff was lifted by the time the plant opened. They still ended up assembling the 750 there, but the larger bikes were done in Japan and the plant did the dirt bikes instead.
IF anyone has better info on this I would like to hear it, because as mentioned, there is not alot written down about VN lore.
