Cars are at present fitted with two different sys-
tems which mainly differ in their control function.
During the 1980 models, the "VIR" system was
replaced by the "Cycling Clutch" system. The
Cycling Clutch system was produced in two ver-
sions, which differ on the 1980 and 1981 mo-
dels. These are factory- fitted. A third version -
the Clarion Cycling Clutch system - has also been
fitted to cars.
