Pretty self-explanatory here. For a motorcycle to attain Antique status, its common that it should be more than 50 years-old. The qualifying age for Vintage-grade bikes is often 20 to 25 years-old. And dont be surprised if you also hear the term Classic bandied about in regard to old bikes. Basically, theyre all simply old. When restored to a high degree of finish, many rare and classic bikes can fetch large sums of money, especially if they have a racing pedigree or a celebrity tie-in. Some bikes in this category are just museum pieces or trailer queens, but many are owned by enthusiastic owners who actually fire up the things and ride them.
