Since when does a bike need lots of heavy chrome bits to make it great? All chromed metal does is add weight.
Chromed plastic peels. The Hondas I've seen have visible tank seams and sloppy (though admittedly perfectly solid) welding on the frames. And yes, this includes the Honda bikes I've owned. Paint quality (especially on their plastic pieces) is also not up to Harley's standards.
None of this is to say that Hondas are bad; they are durable and reliable and the parts on their cruisers, while often less "polished" than those on newer Harleys, are perfectly acceptable. Pretty much every review of a Honda cruiser lists "chintzy details" as one of the bike's downsides though.
Honda and other manufacturers aren't using plastic on cruisers to save weight, they're doing it to save money.
Again, none of this is to say that Hondas are unreliable or somehow less than durable. Hondas are fantastic bikes and they most definitely pay attention in places where such attention is mechanically-necessary. However, that does not excuse the obvious cost-cutting in the trim and detail work on their cruisers.
As far as reliability of contemporary designs goes, I'd put a modern Harley up against anything the Japanese have to offer. Pretty much anything from Harley since the introduction of the Evolution engine has been rock solid.
