Tips on how to select the intervention 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 180/55ZR17).
-
Pirelli Diablo Supercorsa SP;
- Pirelli Diablo Rosso II;
- Pirelli Scorpion Trail.
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 = 180/55-17; front
= 120/70-17), 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 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 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 other 8
intermediate levels. DTC intervention decreases
regularly from level 8 to level 1. With levels 1 and 2,
DTC control unit allows both rear tyre spinning and
sliding sideways when exiting a turn; we recommend
using these levels only on track and to very
experienced riders.
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).
Level depends on grip conditions
The choice of level setting depends greatly on the
grip conditions of the track/path (see below, tips for
use on the track and on the road).
