It comes from Suzuki's Japan marketing.
Knowing what I know about marketing (not much) they probably chose
the name from a list that was passed around the office and/or discussed with
riders.
What we Do know, is that the Skywave name works for Suzuki in Japan
but apparently they felt a different name like Burgman would be
more appropriate for Europe and the US.
This may mean that essentially the name wasn't a big development item
except to match icons, names and shapes to continents.
The name Burgman is so off, it has Japan written all over it. That cancels
out the attempt to appeal to us. We US consumers become
a part of their culture, designs and words.
That's the cool part of the product when we find ourselves riding a
machine that works well anywhere in the
world no matter what a handful of people had once called it.
The process of exporting culture in the form of motorcycles is, I believe
why so many US consumers go for the Japanese product; to escape from
a hopeless form of heavy, gothic looking cheeseburger
bikes that lack diverse styling, ergonomic comfort and technological advancement.
Gothic style tail lights were originally built into early 20th century
automobiles but some manufacturers think that motorcycles look more
American if duck tailed fenders and church window tail lights are built in.
Boy, do we have the upper hand now with our Burgmans.
