Indicator lights
The following lights are mounted on the handlebar dashboard:
5 NEUTRAL LIGHT N (GREEN): illuminates when the gearbox is in neutral.
6 LOW FUEL LIGHT (AMBER YELLOW): illuminates when there are approximately there are about 4 litres of fuel left in the
tank.
7 TURN SIGNAL LIGHTS (GREEN): illuminate and flash when the corresponding turn signal is in operation.
If a turn signal does not work (e.g. burnt out bulb) its incorrect operation is signalled by making the light flash twice
as fast as in comparison to correct operation.
8 ENGINE OIL PRESSURE LIGHT (RED): Illuminates when engine oil pressure is too low. It must turn on at Key-On, but
must turn off a few seconds after the engine has started. The case may occur that the light turns on briefly if the
engine is very hot; it will turn off as the engine rpms increase.
9 HIGH BEAM LIGHT (BLUE): illuminates when the high beam headlight is on.
10 "ENGINE/VEHICLE DIAGNOSIS - EOBD" INDICATOR (AMBER YELLOW): It turns on in the case of an engine or
motorcycle error; in some cases the engine will be locked.
11 "Over rev" rev limiter/traction control indicator "DTC" (RED):
No limiter
1st threshold - no. RPM before the

(*) depending on the model, each calibration of the Engine Control Unit may have a different "setting" for the thresholds
that precede the rev limiter and the rev limiter itself.
