'Factory Custom' is an oxymoron for all intents and purposes. Polaris' Victory Motorcycles also did some in 2014. Mainly cosmetic in both instances. Other MC brands do Limited Editions as well, most notably Ducati, but they are often characterized by improved performance and less weight. Even the Rocket TFC's exhaust 'box' seems the same as that fitted on the R and GT, except for different covers with the 'Arrow' logo.
