Operators Manual
OPERATION OF THE GEAR BOX
The ROTAX® 125 MAX DD2 evo is fitted with a 2-speed gearbox that is changed man-
ually via a shifting device. The engine also has an electronic ignition cut-off which when
changing from 1
st to 2 nd gear, interrupts the ignition, relieving the load from the gearbox
and thereby makes gear shifting easier and faster.
NOTE
Gear shifting might not be possible when the engine is not running as it is not as-
sured that the gear engages.
In principle, the gear shifting is very simple, only some points have to be observed:
Engagement of the 1 st gear
ATTENTION
It is prohibited, to rev the engine up in idle mode in order to change engage the
1 st gear. This could lead to engine failure.
Shifting from 1 st to 2 nd gear
• In principle, this is possible at any engine speed (rpm.). The optimum timing for shifting
is at about 12.200 1/min.
• Due to the electronic ignition cut-off, the gas pedal can stay fully activated during the
shifting operation.
Shifting from 2 nd to 1 st gear
• Due to the high difference in rpm. between the two gears, it is not recommended to shift
down at a speed of over 10.200 rpm.
