For that matter, demand for some motorcycles is so high that prices of several limited-edition examples have appreciated exponentially in recent years.

Several factors add to a bike’s iconography but ultimately a legendary bike is a mechanical artwork that offers a perfect harmony of desire and exhilaration.
