In car magazines (at least in the states), the BMW 3 series is held up as the entry level luxury sports sedan/saloon standard by which numerous cars are compared, including the Mercedes C class, the Lexus IS 300, the Audi A4/S4, the Aucra 3.2 L, the Cadillac CTS, the Infiniti G35 the Jaguar's X-Type, etc.
If as you suggest there is a price cap on bikes being considered in the MO comparison, that is fine and fair (review sites and car magazines do this all the time), but no there is mention of such limtiation in this article.
Obviously, the number of bikes one can afford to compare is not unlimited, but the universe of bikes fitting this article''s decription is really rather small.
