Tips on how to select the sensitivity level
Warning
The 8 levels of the DTC system your motorcycle
is equipped with were calibrated with original
equipment tyres (make, model and size). The use of
tyres of different size to the original tyres may alter
the operating characteristics of the system.
Motorcycle original equipment: (front 120/70ZR17 -
rear 180/60ZR17).
- Pirelli Diablo Rosso II.
In the case of minor differences, such as for example,
tyres of a different make and/or model than the OE
ones, but with the same size (front 120/70ZR17 - rear
180/60ZR17), it may be sufficient to simply select the
suitable level setting from those available in order to
restore optimal system operation.
If tyres of a different size class are used or if the tyre
size differs significantly from the original tyres, it may
be that the system operation is affected to the point
where none of the 8 available level settings will give
satisfactory results.
In this case it is advisable to deactivate the traction
control system.
If level 8 is selected, the DTC system will kick in at
the slightest hint that the rear wheel is starting to
spin.
Between level 8 and level 1 there are other
intermediate levels. DTC intervention decreases
from level 8 to level 1.
Levels 1, 2 and 3 allow both spinning and skidding of
the rear wheel out of a corner: these levels are
recommended only for expert riders, in particular
level 1 is designed for track use.
The choice of the correct level mainly depends on the
following parameters:
1) The tyre/asphalt grip (type of tyre, amount of tyre
wear, the road/track surface, weather conditions,
etc.);
2) The characteristics of the path/circuit (bends all
taken at similar speeds or at very different
speeds):
3) The riding mode (whether the rider has a
"smooth" or a "rough" style).
Level depends on grip conditions: the choice of level
setting depends greatly on the grip conditions of the
