Riding

At engine speeds below approx.
1500 rpm, the centrifugal clutch
remains open and the Scooter is
in idle mode. If the engine speed
is increased, the clutch closes
and the Scooter begins moving.
In the range from approx.
30 mph (50 km⁄h) to approx.
75 mph (120 km⁄h), the engine
accelerates, with the throttle
valve fully open, with a slightly
increasing engine speed in the
vicinity of maximum torque. The
change in speed is achieved by
the CVT. Therefore, the engine
noise only changes slightly in this
speed range.
Speeds above approx. 75 mph
(120 km⁄h) are achieved by in-
creasing the engine speed.
