Tips on how to select the sensitivity level
Warning
The DTC level 1 setting has been calibrated
using the tyres with SC2 compound (Pirelli Diablo
Supercorsa SC2) that are not those originally supplied
with your motorcycle. The use of this level with tyres
having different characteristics may alter the
operating characteristics of the system.
The DTC level 7 setting has been calibrated using
Rain tyres (Pirelli Diablo Rain with size 190/55 ZR17
at the rear) that are not those originally supplied with
your motorcycle. The use of this level with tyres
having different characteristics may alter the
operating characteristics of the system.
The DTC levels 2-3-4-5-6-8 settings have been
calibrated using the tyres originally supplied with your
motorcycle (Pirelli Diablo Supercorsa SP 120/70ZR17
at the front and 200/55ZR17 at the rear). The use of
tyres of different size and characteristics to the
original tyres may alter the operating characteristics
of the system.
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 = 200/55
ZR17; front = 120/70 ZR17), 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 is 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 further
intermediate levels of intervention for the DTC.
Levels 1, 2 and 3 allow the rear wheel to spin and
slide: these levels are recommended on the track
only and exclusively for expert riders: in particular,
level 1 is designed to work at best only with tyres
having SC2 compound.
The choice of the correct level mainly depends on the
following parameters:
The tyre/asphalt grip (type of tyre, amount of tyre
wear, the road/track surface, weather conditions,
etc.).
The characteristics of the path/circuit (bends all taken
at similar speeds or at very different speeds).
I have been using bridgestone and Pirelli slicks with no adverse effects on track but stick to 200 section rear for the roads.
Hope this makes sense.
