Vortex VTS-N OKN

The newborn VTS-N unit, designed for the new OK-N category conceived by the FIA Karting for national championships starting from 2023, has the same shape as the VTS model, but lacks – as per regulations – the exhaust valve and has a rev limiter set at 15,000 rpm. As for the OKJ-N category, the same engine can be used, however, by applying a special exhaust restrictor.
