Riding

At engine speeds below approx.
1800 rpm the centrifugal clutch
remains disengaged, the Maxi-
Scooter is in neutral. When en-
gine speed increases the clutch
engages and the Maxi-Scooter
moves off.
At speeds from approx. 40 km/h
to approx. 120 km/h the en-
gine is running at virtually con-
stant speed and operating in its
maximum torque band. It is the
CVT that effects any change in
speed. Consequently, engine
noise changes only slightly within
this speed range.
Speeds higher than approx.
120 km/h are achieved by an
increase in engine rpm.
