Once set, it will be sufficient to engage first gear and open the throttle: during the first phase of the start, while the driver modulates the release of the clutch, the DPL will keep the Desmosedici Stradale stable around an optimal speed according to the selected DPL level; in the second phase, when the clutch is fully released, the DPL will control the torque delivered to ensure the maximum possible acceleration based on the predefined level.

The DWC EVO more accurately detects the presence and extent of wheelies and intervenes to control them with a greater level of precision, to satisfy the rider's requests even more precisely.

In addition to interfacing with the 6-axis Inertial Measurement Unit (IMU) and adapting the intervention and the slippage to the lean angle of the bike, the software significantly improves power management out of corners thanks to the new "predictive" control strategy. By acting not only on the instantaneous value of the rear spin, but also on its variation, it intercepts the loss of grip more quickly and reduces slippage peaks, thus ensuring a quicker and more regular intervention. All this translates into greater vehicle stability when exiting corners, even in non-optimal grip conditions, greater acceleration and improved performance both over a single lap and on long runs.

The DQS EVO 2, in addition to minimizing shifting times, allows you to downshift without using the clutch, ensuring even more effective braking. The system includes a bi-directional microswitch integrated in the kinematics of the lever which, in correspondence with each gearshift operation, sends a signal to the Desmosedici Stradale control unit. The system acts separately for shifting and downshifting, integrating the action on ignition advance and injection, already present on the up-shift system, with the controlled opening of the throttle valve for downshift operation thanks to full Ride by Wire system management.

The EBC EVO 2 of the Streetfighter V4 2023, optimized based on of lean angle, monitors the position of the throttle, the selected gear and the deceleration of the Desmosedici Stradale shaft during the most aggressive braking, and precisely adjusts the throttle opening to balance the torque forces applied to the tire. The EBC EVO can be set on three levels integrated in the Riding Modes. The software is characterized by a differentiated gear by gear calibration on each of the three selectable levels, according to a new strategy developed to optimize the intensity of the engine brake action according to the load on the rear. In the first braking phase, when there is little load on the rear tyre, the EBC EVO 2 provides less engine brake, then increasing it as you approach the centre of the corner, where the intervention of the engine brake makes the greatest contribution in slowing down the bike and closing the line. Thanks to this modification, which guarantees a more balanced intervention of the control on the engine brake in all riding conditions, rear wheel locking in the most demanding braking sections is also reduced.

ABS Cornering EVO can be set on three levels to fully meet the needs of all riders both in track and road riding, even in the most critical low grip situations. Level 3 is suitable for the road or for low-grip conditions, it guarantees safe and stable braking in all conditions, always maintaining rear wheel lifting under control during the strongest decelerations. Levels 2 and 1, on the other hand, favor braking power and are therefore more geared towards sport riding on high-grip surfaces and on the track. Level 2 is recommended for use on the track novice riders. The system manages both the front and rear braking systems, keeps the "cornering" function active while there is no lift-up control, allowing sportier braking. Selecting level 2 activates the “slide by brake” function that allows you to drift when entering a curve for a spectacular and safe ride. Level 1, not associated by default to any of the Riding Modes, is recommended for experienced riders in track use. It guarantees a racing intervention of the ABS system which acts only on the front wheel. Both the "cornering" function and the anti-lift up intervention are disabled to generate maximum performance.

This system supports the rider by controlling the torque delivered by the Desmosedici Stradale engine as a function of the slide angle. Its goal is to improve performance out of corners by preventing slide angles that would otherwise be difficult to manage. The DSC works thanks to the 6D IMU which provides the vehicle dynamics control unit with information on the dynamics of the motorcycle (such as lean angle, acceleration and much more). Like the DTC EVO, the DSC manages reductions in torque by intervening on the opening of the throttle valves, the reduction of advance and injection cuts. In all situations where rapid DSC intervention is not required, the use of the throttle body valves allows optimal combustion parameters to be maintained, thus obtaining a response from the Desmosedici Stradale and smoother intervention. The DSC is adjustable on two levels: passing from level 1 to level 2, the system allows the rider to more easily control slide angle values ​​that would otherwise be difficult to manage. It is possible to modify the DSC intervention level by entering the menu, from which it is also possible to set the values ​​of DTC EVO and DWC EVO. It is also possible to set the direct control of the DSC through the direct access keys located on the left switch. The DSC set value is always visible on the dashboard.
