VTS-N

VTS-N

DISPLACEMENT 125cc

MAX TORQUE 15.000 RPM

The VTS-N is the first engine in the Vortex Engines range designed to comply with the OK-N regulations, the new category established by the FIA Karting, thanks also to the technical contribution provided by Vortex itself, for national championships, starting from 2023. This new unit takes the shape of the VTS model, the engine reserved for the OK class, the international Senior category of Direct Drive karts, and shares some structural features such as the 104 mm connecting rod and the same type of exhaust, but it lacks – as per CIK-FIA regulations – the exhaust valve and has a rev limiter set at 15,000 rpm. But the special features of this power unit do not end there.
