Founded in 1995 as Meng Kah Auto Parts Trading Sdn. Bhd., RCB began as a motorcycle workshop and parts distributor. Rising demand for higher-quality products led to the creation of the Racing Boy brand, which quickly became a leading motorcycle rim manufacturer in the late 1990s through in-house design and testing.

In 2015, Racing Boy was rebranded as RCB, marking its evolution into a global brand. Today, RCB offers a wide range of premium motorcycle parts, operates in over 30 countries, and provides technical support to more than 20 GP-level racing teams, using motorsports data to drive continuous R&D and innovation.

RCB expanded into suspension and braking systems to meet demanding riding conditions, forming the basis of its tagline, “We Build Riders’ Confidence.” The brand has been actively involved in major racing platforms including MotoGP, ARRC, CEV, and Malaysian Cub Prix, which remains central to product development.

RCB’s commitment to quality has been recognized with prestigious Asian industry awards, and its global presence continues to grow with the establishment of an R&D and commercial facility in Italy.
