Dear Dealers,
This bulletin provides the procedure and settings to correctly measure the performance of the
Panigale V4 on the dynamometer (both inertial and braked).
Riding Mode setting
To measure the correct power and drive torque of the engine it is necessary to select the
“Race” Riding Mode by accessing the dedicated menu of the instrument panel and pressing
button (4) for 1 second; the riding modes available (Race, Sport, Street) are displayed on the
left side of the display while the currently set Riding Mode is displayed on the right side.

Any time you press buttons (1) or (2), the instrument panel will display the riding modes and
the "EXIT" indication. Once the desired “Race” Riding Mode is selected, press button (4) to
confirm.

Setting the “Race” Riding Mode parameters
Parameter information is displayed for any riding mode:
• Engine power (ENGINE)
• DAVC (DTC, DWC, DSC)
• ABS system
• EBC system
• Info Mode
• DQS system
• DES system

For the set “Race” Riding Mode, it is necessary to check that:
The parameter related to the engine power “Engine” is set to “High”.
Access the Setting menu, select "Riding Mode" indication by pressing button (1) or (2) and
press button (4) to confirm.
Select the “Race” riding mode and then the “Engine” parameter confirming with button (4).

Customization options are listed on the left: “High”, “Medium”, “Low” while the set value is
shown on the right. Using buttons (1) and (2) select the “High” level and confirm with button
(4).

The parameter of the Ducati Traction Control (DTC) is disabled:
Access the Setting menu, select "Riding Mode" indication by pressing button (1) or (2) and
press button (4) to confirm. Select the “Race” riding mode and then the “DAVC” parameter
confirming with button (4).

In this way, it is possible to select the “DTC”, “DWC” and “DSC” functions to be customized.
Select the “DTC” function and confirm with button (4). All customization options are listed on
the left (from 1 to 8 and the OFF status), while the set DTC level or status are shown on the
right.
Using buttons (1) and (2) set the intervention level to “OFF” and confirm with button (4).

Setting the dynamometer parameters
Dyno (e.g. Bapro)
If using a roller dynamometer, it is necessary to correctly enter the drive ratio in the
dynamometer configuration (refer to the specific manual).
Since the motorbike runs at high engine rpm, it is recommended to set the drive ratio to the
configuration in which the motorbike runs at half its speed (for example 8,000 rpm).
Inertial dyno (e.g. Dynojet)
It is necessary to use an inductive clamp to acquire the engine speed.
The inductive clamp must be connected to the circuit of the primary coil to measure the
engine speed during the test.
In the specific case of the Panigale V4, to be able to connect the inductive clamp, remove the
fuel tank to access the connectors of the rear bank ignition coils and apply an extension (not
supplied, must be made with local resources) to one of the coil cables.

Connect the extension to the coil cable of cylinder 4 on one side and to the main wiring
connection on the other.

Restore the motorbike configuration paying attention to position the extension outside the
fairing in order to connect the clamp. The clamp must be applied to read the drive current of
the coil (PIN1 or PIN3, taking the marks of the connector as reference).

Ground
(connect the clamp to the
rear bank in the point
shown in the figure)
At this point, the motorbike is ready for the power measurement.
NOTE
Run the test in 6th gear and make sure that the engine has already heated and
started the fans.

NOTE
To fasten the motorbike to the dynamometer, we kindly ask you to apply tie downs
at the back of the motorbike in order to have a certain preload on the rear wheel.
Lower (starting from a reference value) the distance between the fastening hole of
left rear passenger footpeg and the dynamometer plane by 200 mm, as shown in
the figure:

Global guidelines
Ducati recommends performing the test at the reference temperatures of coolant (between
the second and third reference bar indicated on the instrument panel) and air (≤ 30°C) to avoid
having marked corrections of the ignition advance.
Important information for a correct calculation of the power of the engine at the crankshaft
Usually, the most common dynamometers allow measuring the power at the rear wheel. To
have power at the crankshaft it is necessary to multiply the power by a mechanical efficiency
coefficient that takes into account all losses related to the drive.

The Desmosedici Stradale engine has a counter-rotating crankshaft and, compared to classic
engines, it has a dedicated chain tensioning sprocket. To have the power value at the
crankshaft it is necessary to correct the measurement taken on the inertial dynos considering
an additional coefficient that combines the different efficiencies indicated in the following
table:
Couplings

Coefficients

Idle gear

0.98

Primary drive gear

0.98

Drive ratio

0.98

Chain

0.95

The total coefficient to apply is 0.8941.
Power at the crankshaft = Power at the rear wheel / 0.8941
Similarly, if you wish to calculate the power at the crankshaft that takes into account only of
the idle gear (by pulling the clutch at the end of the launch during the deceleration) you will
need to consider only the coefficient of the idle gear.
In this case, the coefficient to apply is 0.98.
Power at the crankshaft = Power at the rear wheel / 0.98
