Let's face it, we are a tight and dedicated community. We have our own vernacular. Some of it may not be "web-searchable." (I am often stymied that I search for V11 answers and find = V11LeMans.com !)
"colloquial?" I reckon so.
There are the traditional V-twin frame monikers (Loop, Tonti, Spine) that have, now, gone by the wayside. Yet, who first coined "Spine Frame?"
Not sure that is what Tony Foale called the original?
