2.5. Electric starter
By pressing the start button, the circuit between the battery and the electric starter will be closed by
a relay. The electric starter drives the starter gear on the crankshaft via an intermediate gear with
free-wheeling, until the engine starts to run. An automatic switch reset from "START" to "ON" is
integrated.
2.6. Electro-pneumatical exhaust timing control
The engine type 125 MAX DD2 evo is equipped with an electro-pneumatic exhaust control. The
ERAVE (Electronic ROTAX Adjustable Variable Exhaust) system is controlled by an electro-
pneumatic valve via the ECU. The vacuum required is provided by the engine crankcase.
At engine stop, the exhaust valve is in idle mode and therefore in the open position. With the
engine running, it closes or opens the electro-pneumatic valve of the exhaust depending on the
speed and, therefore, it provides optimum performance characteristics.
2.7. Intake silencer
The intake silencer incorporates an air filter to clean the intake air. The intake silencer has been
designed for optimum reduction of air intake noise level and represents a tuned system with the
engine.
The air filter consists of several layers and has been optimized in the area of air passage and filter
efficiency. If soiled or during engine maintenance work, clean the filter with biodegradable products.
2.8. Exhaust system
The exhaust system is designed as a resonance system with an after-muffler and represents a
tuned system with the engine.
2.9. Gear box
The power transmission to the rear axle takes place via a manually shiftable integrated 2-speed
gearbox and not as usual, via a maintenance-intensive chain drive. Changing the gear activates
the gear shift fork as well as a shifting sleeve, which slides on the hollow shaft between the 1
st
and
2
nd
gear and then engages in the respective idle gear.
The gear is kept in position by an index pin, which keeps the gearshift fork in the selected position,
1
st
gear, neutral or 2
nd
gear.
To allow shifting into the 2
nd
gear without lifting the foot from the gas pedal, the ignition is cut off for
a moment when actuating the shifting paddle.
2.10. Electronic Shifting Assistant (ESA)
To optimize the shifting from 1
st
to 2
nd
gear, the ignition is interrupted for a short time. This releases
load from the gearbox and, like this, gear shifting is faster and less stressful for the gearbox.
2.11. Fuel pump
The fuel pump functions due to the alternating negative pressure and overpressure in the
crankcase and sucks fuel from the fuel tank into the carburetor via the fuel pump. In the suction
