The Malaysian Cub Prix Championship is a national-level underbone or moped racing series for motorcycles with displacements from 100 to 150cc. The tournament is a grassroots developer with the main objective of discovering and developing Malaysian motorcycle racing talents.

An underbone is a type of motorcycle that uses structural tube framing with an overlay of plastic or non-structural body panels and contrasts with monocoque or unibody designs where pressed steel serves both as the vehicle's structure and bodywork. Outside Asia, the term underbone is commonly misunderstood to refer to any lightweight motorcycle that uses the construction type, known colloquially as step-throughs, mopeds or scooters.
