Classic motorcycle is not necessarily collectible, it can also mean that it’s just old. There is no widely accepted definition for how old a motorcycle must be to qualify as vintage or classic, but some experts say it’s anything older than 1974, and others lump in Japanese bikes from the early 1980s. To be both classic and collectible is a function of a number of factors, including the condition and originality of the motorcycle, when and how many of the bikes were made, how long the company making it was in business and whether or not the bike was associated with someone famous.
