The Catalan company OMK (OMiKron), one of the few and most relevant national developers specialized in video games for the Amstrad PCW 8256, 8512, and 9512, was at the end of the 1980s finalizing what was to become its last major project within the motorcycle high-speed racing genre.

The title, 500 c.c. Championship, was conceived as a high-speed motorcycle racing simulator, clearly inspired by SEGA's arcade Super Hang-On, bringing that direct and frantic style to the PCW environment. The OMK team poured much of their technical and creative capacity into this development, betting on digitized graphics, different types of scroll, and numerous circuits, in which the player had to risk reputation and survival to achieve glory in the championship.

According to the information available in 1990, the game was scheduled to be published in a very short timeframe and, in principle, was announced for multiple platforms, both 8 and 16-bit, which represented an unusual ambition for a company traditionally focused on the PCW.

To this day, we do not know if this game was ever released on the market, although we have already been surprised by other discovered releases whose existence on the market was previously unknown. In 1990 it was announced that it would be available "in the very short term," but there are no records or proof that the final product ever reached commercialization. The lack of mentions in magazines of the era, complete game listings, or software databases confirms that the game remained in the development stage or was cancelled.
