The godfather of ‘Merlin Nation’ is Umberto Merlin. A former driver and mechanic in Italy, MRC was established in 1984 working with various chassis and engine manufacturers. Eventually, MRC began designing and manufacturing their own chassis brand – the Merlin.

The relationship between Merlin and the MerlinUSA began in 2003, with a meeting between Umberto and Jamie Sieracki. Once they got around the obvious language barrier, a formal working relationship was formed and the chassis made its debut with Sieracki’s C-G Racing outfit at the 2003 Daytona KartWeek.

From there, the Merlin brand has been a regular fixture in North American karting, competing at all levels of the sport. The continued relationship between MRC and MerlinUSA has led to developing chassis that focus on the US market, to better suit the type of conditions, tracks and tires that utilized in this country.

The focus with the frame design is to utilized supplied components such as a Tillett seat and Douglas SE Magnesium wheels to avoid several required “upgrades” for optimum performance.
