The Mercury RR keeps faith with the company mission "Designed, Engineered, Manufactured, 100% Made in OTK - Italy" at the base of all OTK Kart Group products. The rigorous control of the entire design and production chain, thanks also to the use of automated processes that guarantee extremely high-quality standards, has always been the distinctive element of the Italian company. An approach that has led over the years to the victory of five world titles, a KF3 World Cup and three CIK-FIA Asia-Pacific titles. These results were once again confirmed by the 2021 season, which was no less generous in terms of satisfaction thanks to the two vice-world championship titles in the OK and OKJ categories, as well as the success in the FIA Karting European Championship of OK-Junior category.
