I was thinking about retro bikes, and in particular, phony features on retro bikes that make them look like the original designs.
For example, the "timing cover" on the current Triumph Bonneville range. It is very charming that it mimics the iconic, heart-shaped one of the original Triumph twins, but it is just a styling feature. The classic Triumph timing cover was heart shaped because it framed the gear train of the twin, highly set camshafts - it just had to be that way. Modern Triumphs have overhead camshafts, so this cover design is just a gimmick, and if it adds any unnecessary weight to the engine then it is arguably a misconceived one.
I think the UCE Bullets are on a better footing here. RE have made huge structural changes to their engine but it still looks classic, and in its own new way, because it is still a long stroke, push-rod single under the skin.
I think that the crucial difference between the two companies is that RE just had to keep it real because of tight budgetting and the practical needs of their domestic market, but Triumph had the capital to "boutique" their design in the now standard top-down, marketing department led way that we do things.
