[dropcap]W[/dropcap]ith the homologation of the latest DDS and DDJ the phase of design and of research and development, in which all of our best human and technical resources have given their best to create new engines, is closing, ready to face the challenge on track, which has always seen us excel.
The quality of the DDS and DDJ projects, aimed at new OK and OKJ categories are several, actually they can keep innovation and research, directed towards solutions which we have already experienced before, winning. In particular, there is returns to direct drive while maintaining a displacement of 125 cc.
The RKZ is descendant of the multi-titled RVZ engine, World and European Champion already, which is the expression of the most refined evolution.
Our new engines, DDS, DDJ and RKZ were tested at the test bench and on the track; every solution adopted was approved after a thorough process of material selection and setup. The technical fiches summarize, and in part make understand the much Vortex effort, but now we look forward to the track challenge, to express ourselves to the maximum and to show the potential of our latest models.
