Vortex Engines VTJ (OKJ CLASS)

Vortex Engines VTJ (OKJ CLASS)

On the occasion of the CIK-FIA homologation session, the Vortex engine range is completely renewed.
For the OK and OKJ categories respectively, the VTS and VTJ models make their debut, as the direct successors of the Vortex DTS and DTJ, able of winning no less than five world titles - three in Junior, two in Senior - in the last four years.
Among the various innovations introduced, an unprecedented production process stands out: the paired crankcase boring. This further processing stage of the engine crankcase makes it possible to achieve a higher final quality level of the product, with positive effects both in terms of quality and repeatability of the various models produced as well as in terms of performance. The VTS also sees the introduction of a new exhaust valve design, a solution that ensures greater efficiency at low revs and improved engine performance.
The main featured inherited from the previous versions of both engines remain unchanged: lightness, assembly and use easiness, effective arrangement of mass and centre of gravity, compact dimensions and reliability.
