SUPER ROK
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 Dell’Orto.
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. |
