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 tyres: (front 120/70-17 - rear
240/45-17).
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 (rear = 240/45-17; front
= 120/70-17), it may be sufficient to simply select the
suitable level setting from those available to restore
optimal system operation. If tyres of a different size
class are used or if the tyre dimensions differ
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 is it is advisable to deactivate the
traction control system. If level 8 is selected, the DTC
control unit will kick in at the slightest hint that the
rear wheel is starting to spin.
Between level 8 and level 1 there are a further 6
intermediate levels. The level of DTC intervention
decreases in equal steps from level 8 to level 1.
Levels 1 and 2 are specifically designed for OFF-
ROAD conditions and do not ensure a suitable control
with poor grip on asphalt.
When level 3 or 4 is selected the DTC control unit will
allow the rear wheel to spin and also slide sideways
on exiting a corner; we recommend that this setting
is only used by very experienced riders on the track.
The choice of the correct level depends on 3 main
variables:
1) The 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).
The relation of the DTC intervention level to grip
conditions:
The choice of level setting depends greatly on the
grip conditions of the track/circuit (see below, tips for
use on the track and on the road).
