The fully adjustable Diavel V4 suspension consists of 50 mm diameter upside-down forks (with compression and preload adjustment on the left tube, and rebound on the right tube) and a single shock absorber with a separate piggyback reservoir. The wheel travel is 120 mm at the front and 145 mm at the rear, 15 more than Diavel 1260, with positive effects on the comfort of both the rider and the passenger.

At the front, the braking performance of the Diavel V4 is guaranteed by Brembo brakes with Stylema® radial monobloc calipers operated by a PR16/19 radial brake master cylinder with integrated aluminium reservoir acting on two 330 mm diameter floating discs. At the rear, on the other hand, the 265 mm diameter disc is braked by a two-piston caliper, also produced by Brembo.

The Diavel V4 is fitted with five-spoke wheels featuring an exclusive design with machined surfaces. At the front, the wheel rim is 3.5” x 17”, while at the rear there is an 8.0” x 17” rim. A 120/70 ZR17 tyre is mounted on the front rim, while the rear tyre is 240/45 ZR17. The tyres are Pirelli Diablo Rosso III.

The riding position of the Diavel V4 continues to be sporty but comfortable and accessible, with a saddle positioned at 790 mm from the ground and completely redesigned to offer greater longitudinal space, support in strong acceleration and ample freedom of lateral movement of the body when leaning, thanks also to the excellent connection with the tank and to the footpegs located in a central position. On the Diavel V4 the wide and raised handlebars have been brought 20 mm closer to the rider's body to improve comfort and control in all situations.

The rider can manage all the electronic systems through backlit controls on the handlebars and the new 5-inch color TFT dashboard, which also offers Bluetooth connectivity to pair your smartphone and use it for calls, text messages and music, or use the Turn-by-turn navigation system (available as an accessory) via the Ducati Link App.

If the accessory Turn-by-turn navigation system is installed, the display provides a dedicated display, in which half is devoted to standard information (speed, engaged gear, tachometer, etc.) and the other half is reserved for Turn-by-turn navigator instructions, implemented through the Ducati Link App installed on the smartphone. The destination is set on the latter; by activating the start of navigation, the instructions will then be displayed on the dashboard.

The ABS system of the Diavel V4 includes the "cornering" function, which extends the ABS intervention even when the bike is leaning. The ABS Cornering appropriately uses the signals of the Bosch IMU inertial platform to optimally dose the braking power of the front and rear wheels even in critical situations and with the bike at an angle.

By interacting with the Riding Modes, the system is able to offer solutions suitable for every situation and riding condition as well as rider preference. The system acts with three different levels of intervention. Level 1 offers maximum performance for sporty riding, does not have the Cornering function, the rear lift detection (lift-up) activated and allows the rear to yaw when braking with ABS applied to the front only.

Level 2 ensures a balance between front and rear without rear wheel lift detection but with Cornering functionality active and calibrated for sporty riding. Level 3 allows the optimization of the braking action with detection of rear wheel lift and the Cornering function activated and calibrated for maximum safety (safe & stable configuration).

The new Ducati Traction Control (DTC) EVO 2 strategy derives from the Ducati Desmosedici GP18 and is already used on the Panigale V4 and Streetfighter V4 families. In addition to interfacing with the 6-axis Inertial Measurement Unit (IMU) and adapting the intervention and slide to the lean angle of the bike, the software significantly improves power management out of corners thanks to the new "predictive” control strategy. 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 less-than-optimal grip conditions, greater acceleration and improved performance.

Furthermore, the DTC EVO 2, in addition to management of the ignition and injection advance, provides for the intervention of the valves of the throttle bodies when a rapid intervention of the control is not necessary, allowing to maintain optimal combustion parameters and obtain smoother engine response and intervention.

The DTC EVO 2 can be set on 4 different levels (3 in dry conditions and 1 in wet conditions), allowing the rider to adapt the control strategy to his or her riding style and grip conditions, obtaining maximum performance.

The Streetfighter V4 is also equipped with the latest version of Ducati Wheelie Control (DWC) EVO, adjustable on 4 levels. This system, using information from the Bosch 6D IMU, controls wheelie and allows for maximum acceleration performance with ease and safety. The DWC EVO more accurately detects the presence and extent of wheelies and intervenes to control them with a greater level of precision, so as to satisfy the rider's requests even more accurately.

This system, adjustable on three levels, is able to guarantee lightning-fast starts, allowing the rider to concentrate only on the management of the clutch release, allowing the "Dragster" soul of the Diavel V4 to express itself fully. Once set, it will be sufficient to engage first gear and open the throttle: the DPL during the first phase of the start, while the driver modulates the clutch release, will keep the V4 Granturismo 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.

For its operation, the DPL exploits the functions of the DWC and always keeps the DTC active, to guarantee the highest level of safety in every situation. The system is automatically disengaged above the speed at the end of the manoeuvre, or once the third gear is engaged. To preserve the clutch, the system uses an algorithm that allows only a limited number of consecutive starts. The number of starts available is restored when the rider uses the bike normally.

The DPL is adjustable on 3 levels. Level 1 is the one that privileges starting performance, level 3 is the most “safe and stable”.

The DQS EVO 2 with up / down function, developed for the Panigale V4, makes use of the information on the lean angle to maximize the stability of the bike during the shifting phase when cornering.

The DQS EVO 2, in addition to minimizing shift 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, at each gearshift operation, sends a signal to the control unit of the V4 Granturismo. 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 down-shift operation thanks to the full Ride by Wire system management.

Cruise Control makes highway transfers more relaxed.
