A feature of flat track motorcycles is the flat track side plate. It is a plate, usually made of metal, which is attached near the rear wheel to the side of the motorcycle. In flat track competition, the side plate is used for a variety of purposes:
Identification : During the race, spectators and officials can track and identify runners by displaying the runner's number on the side plate.
Advertising : Sponsor or brand logos may be present on the side plates, providing visibility to the runner's or event's partners.
Aesthetics and tradition : Side plates give flat track motorcycles a touch of style and a traditional look. Often, they are adapted to the style of the rider and the bike.
Protection : In addition to being aesthetic and useful, the side plates can also protect the motorcycle or rider against splashes of mud and gravel.
The side plates of flat track racing motorcycles contribute to the visual identity of the sport and the authenticity of these racing motorcycles.
