DescriptionThe whole story▼
The JP ACCGP DU056 is the short-stroke throttle for the Ducati Streetfighter V4S across 2025 and 2026, the S-spec naked bike whose semi-active suspension reacts to throttle input as much as to the road. A sixty-degree rotation gives that electronics-dependent chassis a cleaner, more deliberate signal to work with.
Key Features
- Ducati Streetfighter V4S (2025–2026)
- GP Series ride-by-wire quick throttle with a sixty degree rotation angle
- Progressive return spring, preload adjustable externally in three positions
- CNC-machined from solid Ergal 7075
- Plug-and-play on the motorcycle's own connector
- Standard throttle assembly refits at any time
Suspension That Listens to the Throttle
The V4S's semi-active suspension adjusts damping partly based on how the throttle is being used, which means an imprecise or over-rotated throttle input feeds imprecise data into a system meant to react to exactly that. A shorter, more direct rotation gives the electronics a cleaner signal to interpret, particularly through the quick transitions between braking and accelerating that a naked bike like this one is ridden with.
From Trail-Braking to Hard Acceleration
Riding a Streetfighter V4S quickly means spending a lot of time in the transition between trail-braking into a corner and picking the throttle back up before the apex, a window where small, controlled inputs matter more than outright speed of movement. The reduced rotation makes that early pickup easier to judge, especially for riders used to the wider arc of the standard throttle.
Plug and Play Into the S-Spec Electronics
Fitting the GP Series throttle changes nothing in the wiring between the twist-grip and the throttle body sensor, so none of the S-spec's additional electronics, including the semi-active suspension control, need recalibrating beyond the standard diagnostic throttle position reset performed after installation. The upgrade sits entirely on the mechanical side of the system.
Three Spring Settings for a Heavier Front End
The V4S carries more electronics and a more elaborate suspension package than the base Streetfighter, which changes how the bike loads and unloads under throttle. The progressive return spring's three external preload settings let a rider match the throttle's snap-back firmness to how they brake and accelerate on this particular chassis, rather than accepting one fixed feel.
Billet Ergal Under Repeated Hard Use
A naked superbike like the V4S tends to get ridden hard on sections of road most owners know well, which means the throttle sees repeated full-rotation inputs rather than occasional ones. Machining the shorter cam from solid Ergal rather than stamped material keeps that geometry, and the feel it produces, consistent through years of that kind of use.
Reversible When the Bike Changes Hands
Because the GP Series throttle uses the stock connector and mounting points, removing it and refitting the standard Streetfighter V4S throttle is a straightforward job rather than a project, useful for an owner preparing the bike for sale or simply wanting to return to factory specification for a service or warranty inspection.
