DescriptionThe whole story▼
The JP ACC DU020 is a machined replacement for the SuperSport 939 S's standard throttle assembly, aimed at riders whose hand runs out of travel before the engine runs out of revs.
Key Features
- Ducati SuperSport 939 S (2017–2020)
- Ride-by-wire quick throttle with a sixty degree rotation angle
- CNC-machined from solid Ergal
- Plug-and-play on the motorcycle's own connector
- Diagnostic reset required after fitting
- Standard throttle assembly refits at any time
Ohlins and a Quickshifter
The S specification adds the suspension and the shifter, which turns a comfortable sports bike into one that can be ridden quickly without complaint.
A Track Argument First
The case is strongest where the throttle is opened and closed hard and often. On a long motorway run the shorter sweep is simply a different habit.
The Sensor Inside
Ride-by-wire measures grip angle and hands the figure to the engine controller. The assembly is therefore an instrument as much as a mechanism.
Scrutineering
Nothing here affects a technical inspection at a circuit. The assembly is a standard-looking part in a standard position doing a standard job.
Bar Diameter
The assembly is made for the motorcycle's own handlebar, which is why the part number is model specific rather than a size.
The Learn Routine, in Plain Terms
The controller is told to look at the throttle with the grip released and write down what it sees. Everything after that is measured from that number.
On a Motorcycle With Modes
The softest mode still softens and the sharpest still sharpens. What changes is the distance travelled to reach whichever response the mode provides.
Riding Standing Up
Off road the wrist grips from above rather than behind, and a shortened rotation leaves less room to meter drive on a loose surface. That is exactly where metering matters most, which is worth weighing before ordering for a tall machine.
Small Screws, Aluminium Threads
The clamp fasteners are short, they thread into a light alloy and they hold a control that matters. The figures are low and looking them up takes a minute. Stripping one turns a straightforward afternoon into a repair nobody planned.
