Any used model of the over 50 different brands of motorcycle that the National Auto Dealers Association evaluates is a NADA motorcycle. Web users may find price information and comparison tools for these motorcycles on nadaguides.com
Users often compare NADA with Kelley Blue Book because it is a valuation service for automobiles that offers consumers an objective guide to the price and value of used vehicles. As of 2015, NADA offers information about over 50 different brands of motorcycle, often comprehensively covering the models those brands manufacture. Examples of brands that NADA reports on include Harley-Davidson, Indian Motorcycles, Red Horse Motorworks, Yamaha and Thunder Mountain Cycles. They also evaluate APC Motorcycle Company and Hyosung Motors America.
While NADA covers the vast majority of American motorcycle brands, the organization also reports on some of the most popular foreign brands such as Honda, Yamaha, Kawasaki, Suzuki and Ural. NADA also offers price information for secondhand trikes from manufacturers such as Can-Am or Boss Hoss, counting them as motorcycles for the purposes of categorization.
NADA does not limit its services to the Internet; the company also provides dealers with a hard copy value book and appraisal guide. The consumer edition of this appraisal guide is no longer in print, but it is available online.
