I read an article about marketing some years ago. The point was that adverts are designed to inspire feelings in the viewer that force them to make the purchase. I would assume that a certain combo or colors, materials, shapes and textures attract each of us to something about our bikes.

It would be a bit much to expect people to know and tell truthfully what the attraction is. Thick chrome plating with tiny speckles of rust makes me tingle but care nothing for truck bumpers.
