Engine, Vortex RTZ

This model was created by rigorously following the basis distinguishing Vortex products: production quality, machining refinement and innovation. The RSZ is provided with a strongly developed crankcase, machined by CNC and able to achieve even higher quality standards.

Among the main innovations of the RSZ is the 110mm connecting rod, now shorter than the previous model RKZ, the World Champion engine.
Such solution features a torque curve able to ease the driver to race on short to mean length tracks.
The engines is completed by a new head, dismountable into two pieces, born from the incredible work that already led to the 2018 World Championship victory.
Both new models will be equipped with an expressly designed muffler.
