Physically large, low revving, high-capacity engines have associations with "quality" that date back to the early beginnings of the internal combustion engine.
In modern era we have redefined quality as "fitness for purpose". One guy's definition of quality vacation might be a ship-borne cruise and another's an overland trip to the Yukon.
An 1800 Harley and a Goldwing may rev at different rpm's at 80 mph. They are both high-quality designs that have been thoroughly engineered. However riders experience the end result in different ways.
It is great for us as consumers that we have a choice.
