New geometry of the frame RY32RX-S16 - DD2. New support axle bearing in forged aluminum. New front brake system RR-EVO. The DD2 karts, both the 30 mm and 32 mm versions, have not undergone any significant changes. Starting from the S18 models, also for this racing season we have conducted an important development activity aimed at optimizing the overall performance of the kart. The intervention has involved the evolution of the frame geometry, using new materials with improved mechanical characteristics and revising of some accessory components. New technical details have also been introduced, projected to increase the products dynamic efficiently and construction quality of the products.
