Racer 401 T, TDX and Rookie: these are the names of the products in Tony Kart's “model year 2025” chassis range. Featuring the design and the evolution of all models is undoubtedly the synergy between OTK Kart Group's R&D department and the Tony Kart Racing Team. A historical cooperation that has allowed the Italian company to develop different technical solutions introduced with the new product range, always keeping firmly in line with the company “Designed, Engineered, Manufactured 100% made in OTK - Italy” philosophy, which involves the use of selected and quality-controlled materials, fabricated with machined processes that guarantees high production standards and accuracy of the products. All of this, of course, within the OTK Kart Group's Chassis Division factory in Prevalle.
