DESCRIPTION

ROK is a 125cc single-cylinder 2 stroke engine by Vortex, with reed valve admission in the crankcase. It is mixture-lubricated and liquid-cooled with integrated water pump. It has got a self-generating digital ignition and an integrated electric starter, which the battery is dedicated to. It is provided with a balancer shaft, which reduces the vibrations. A centrifugal dry clutch makes it possible to keep the engine on even when the kart is still.

JUNIOR ROK
By changing the exhaust, the Rok engine decreases in power from 29Hp to 19Hp. That’s the Junior Rok engine!

DESCRIPTION

SUPEROK is the ultimate evolution of the ROK engine by Vortex, conserving many of its important characteristics, but featuring an amount of innovations.
Not changing the displacement of 125cc and the reed admission in the crankcase, the reed block is now bigger, and the carburettor is a d.36mm by Dellorto.
The new cylinder, always with liner, has got a 5-transfers scavenging, and the 3-ports exhaust is provided with pneumatic power valve.
The digital ignition has a different advance diagram; the exhaust plant is a new design with integrated silencer; the rotor of the centrifugal clutch is now monolithic.
