A 1:1 replica is an exact copy of an object, made out of the same raw materials, whether a molecule, a work of art, or a commercial product. The term is also used for copies that closely resemble the original, without claiming to be identical. Also has the same weight and size as original. Replicas have been sometimes sold as originals, a type of fraud. Most replicas have more innocent purposes. Fragile originals need protection, while the public can examine a replica in a museum. Replicas are often manufactured and sold as souvenirs. An inverted replica complements the original by filling its gaps. Sometimes the original never existed. It is logically impossible for there to be a replica of something that never existed.

This is not the actual vehicle or clothing worn during the race by the racer, but a fully officially approved brand-new street-legal product in similar looks. Typically found in helmets, race suits/clothing, and motorcycles, they are coloured in the style of racers, and often carry the highest performance and safety specifications of any street-legal products. These high-performance race-look products termed "Replica", are priced higher and are usually more sought-after than plain colours of the same product. Because of gun ownership restrictions in some locales, gun collectors create non-functional legal replicas of illegal firearms. Such replicas are also preferred to real firearms when used as a prop in a film or stage performance, generally for safety reasons. A prop replica is
