Operation Of The Gearbox; Activating The Reverse Mode - Rotax Rm1 Benutzerhandbuch

3.4. Operation of the gearbox

The ROTAX RM1 Kart is fitted with a 2-speed gearbox that is changed manually via a shifting
paddle. The engine also has an electronic ignition cut-off which when changing from 1
interrupts the ignition relieving the load from the gearbox and thereby makes gearshifting easier
and faster.
Note:
The gearshifting in principle is very simple, only some points have to be observed:
Engagement of the 1
•
As a matter of principle this is only possible at idling (engine speeds below 2.500 r.p.m.) as at
higher r.p.m. the centrifugal clutch is already engaged.
Note:
Shifting from 1
•
In principle this is possible at any engine speed (r.p.m.). The optimum timing for shifting is
reached when the red LED flashes briefly on the multi-functional display.
Due to the electronic ignition cut-off the gas pedal can stay fully activated.
Shifting from 2
•
Due to the high difference in r.p.m. between the two gears it is prohibitive to shift down at a
speed of over 10.200 r.p.m.
Attention: If shifting from 2

3.5. Activating the reverse mode

The reverse gear is intended only for reverse driving in the pits and to bring the vehicle back to the
race track after unintentional exit, without getting out of the Kart. By no means is it intended to
drive at higher speeds.
The possibility to drive backward is achieved by a change of the engine rotation sense, thus
without a mechanical gear. To do so, the ignition timing of the engine is controlled in a way to
change the engine from forward to backward rotation and vice-versa.
Actuate the push-button for activation of the reverse mode at idle speed.
As soon as a warning signal is heard, the vehicle can be driven backwards by accelerating.

Gearshifting is not possible when the engine is not running as it is not assured that
the gear engages and the shifting mechanism might get damaged.
