Vortex RVX 125
RVX 125 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.
