Non-female person here. Ages ago I worked in a Triumph/Vincent (motorcycle) shop, and I remember a couple of the women riders mentioned that they'd pick a motorcycle based on the way it vibrated. Might be a coincidence but they both rode Harleys.

Personally, I was more interested in the vibrations transmitted through the handlebars and ways to get those handlebars away from any harmonic of a bike's normal vibration. I think those conversations both started with a discussion of whether bar-end weights worked for that purpose (they do, but only to a moderate extent).
