The passenger seat cover is supplied as standard and easily removable, making it possible to transform the Diavel V4 from a two-seater to a single-seater easily.

Powerful, with high torque at all rpm (peak 12.8 kgm at 7,500 rpm), but also extremely light and compact, the 168hp V4 Granturismo derived from the Panigale V4 and Streetfighter V4 Desmosedici Stradale is at the same time smooth, regular and responsive from the lowest rpm.

The extended deactivation system for the rear cylinders allows the engine to run as a two-cylinder or four-cylinder unit, producing a change in the tone of the exhaust sound when switching from one mode to the other. The V4 Granturismo has a deeper sound with lower frequencies when only the two front cylinders are active. The frequencies become higher when all four cylinders are operating. Unmistakable Ducati sound.

The record valve adjustment check interval at 60,000 km and the scheduled oil change every 15,000 km or 2 years mean only one thing: more time to drive and enjoy the ride.

The development of the V4 Granturismo also took fuel consumption and comfort into account: the extended rear-bank deactivation system acts both during stops with the engine running and when running at low speeds to reduce fuel consumption and improve thermal comfort for rider and passenger.

For the V4 Granturismo, the main service interval for the valve clearance check is 60,000 km, a record that raises the standard of reliability and reduces maintenance costs.

Cruise Control makes highway transfers more relaxed.

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 Diavel 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, to satisfy the rider's requests even more accurately.

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 operating parameters of each control are associated by default with the four Riding Modes with which the Diavel V4 is equipped: Sport, Touring, Urban and the new Wet mode, designed specifically for low-grip surfaces. 
  

Sport Riding Mode:
The intervention of Ducati Traction Control and Ducati Wheelie Control is reduced to a minimum and the ABS is set to level 2 which allows controlled lifting of the rear wheel to maximize braking performance, while maintaining Cornering functionality. It is the ideal choice for experienced riders who want to enjoy the maximum performance of the Diavel V4.

Touring Riding Mode:
The ABS is set to level 3, the safest and most prudent one thanks to the limitation of rear wheel lift, the optimization of combined braking and the active Cornering function.

Urban Riding Mode:
DTC and DWC move to a very high level of intervention. The ABS is set to level 3.

Wet Riding Mode:
The RM limits maximum power to 115 hp with a particularly gentle throttle response (Low Power Mode) and the default level of electronic controls is set to offer maximum stability ensuring better grip and steadiness.

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.

The ABS is set to level 3, the safest and most prudent one thanks to the limitation of rear wheel lift, the optimization of combined braking and the active Cornering function.  

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.

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.

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.
