Only modifications specified within the approved homologation documents for each model are permitted. The lower fairing must be designed to accommodate at least half the capacity of the oil and engine coolant used in the motorcycle if the engine is damaged. Only brake discs made of iron are permitted. Number plate colours are white background with black numbers (RAL colour table values: 9005 black and 9010 white).
