is the latest engine manufactured by VORTEX, and is CIKFIA
homologated and assigned to the KZ1 and KZ2 classes.
The new engine has in common with its successful forerunner, RVS
125, the single-cylinder architecture with water cooling through an
external pump and power delivery via six-speed gearbox.
The RVX project offers a completely new, more compact and
lighter crankcase that unables the cylinder and head to be
mounted in a nearly vertical position. Such inclination improves
the dynamics of the airflow as it enters the crankcase.
The reed valve and the cylinder group evolution provided
accurate thermodynamic research regarding the air flow and
the liquid cooling channels. Through these changes and the
resulting increase in cooling system performance, Vortex has
achieved maximum power output.
Close attention has been dedicated to every single detail.
Changes include the following: lighter clutch cover, which better
surrounds and protects the mechanic parts; relocated clutch
cable attachment to improve ease of use, and a practical ability
for clutch adjustment; further more the vacuum pump has been
moved from the left to the right side, providing the possibility to
set the fuel pump on the engine through suitable clamps.
Not to be forgotten, an air flow passage has been created on
the lower half of the crankcase; helping to improve the flow of
air which assists the cooling under the engine.
