The Rok is a 125cc single-cylinder 2 stroke engine by Vortex and it has three prized qualities for the present karting world which are: easiness
of use, high performances and relative low maintenance costs.
After a multi-year experience in the karting world, we in Vortex have created an engine which is easy to use and also exciting to drive.
Thanks to the centrifugal dry clutch, with the Rok 125cc it is possible to stop with the engine on.
On pushing the green button the engine starts without faltering and without the need for any other help.
The Rok has been made by paying great attention to every single detail; this is the most important quality characterizing all Vortex productions.
The balancer shaft reduces the negative vibrations and the rpm limiting device maintains the engine at 14.000 rpm; in this way it is possible
to keep prices low and extend the life of the engine.
The reed admission, the ø 30mm Dell’Orto carburettor and the water cooled by an integrated water pump inside the carter complete a refined and well calibrated technical package, guaranteeing a fantastic driving sensation which satisfies the driver makes him self-confident.
