ROTAX DD2. Like every year, we present the new developments of the 2025 season that will be introduced in the Birelart – Freeline karts and products for the 2026 season. The acronym that characterizes the new models for 2026 will be S19. 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. The results obtained on track, both nationally and internationally, confirm the validity of the work made. CHASSIS MOD. DD2 RY30 Hom.007/CH/10 & RY32 Hom.007/CH/12 The DD2 karts, both the 30 mm and 32 mm versions, have not undergone any significant changes. NEW FREELINE PARTS NEW GRAPHIC: like every year we revised the graphic try to give an always more aggressive, modern, and recognizable look that distinguishes the BirelART brand.It will be standard on all Birelart DD, SH, DD2 & MINI models. NEW BUSHING HI TECH: A new one-piece caster and camber adjustment bushing has been developed and tested. This will be able to increase or decrease caster by plus or minus 4 degrees and adjust camber from positive to negative by approximately 12/14 mm. Will be possible to make these adjustments from the top of the "C" stub axle (it will no longer be necessary to use eccentrics at the bottom of the "C") very quickly and easily.It will be mounted as standard on DD, SH, and DD2 karts.
