DescriptionThe whole story

A Streetfighter V4 carries the same 1,103 cc engine as the Panigale in a chassis with no fairing to hide behind — which means everything bolted to the top yoke is on display. The standard ignition barrel is the one part of that view nobody chose. JP KS DU021 replaces it with a machined button, across the base bike, the S and the SP.

Key Features

  • Covers Streetfighter V4, V4 S and V4 SP, 2020 through 2024
  • Deletes the ignition block and key from the cockpit entirely
  • Roughly 350 g lighter than the assembly it replaces
  • Ergal billet, anodised, with an IP69K-sealed push button
  • Key Box supplied for the Ducati immobiliser
  • Standard mounting points and connector — no drilling, no splicing

Naked Bikes Show Their Work

On a faired Panigale the ignition area is half hidden by the screen and the clocks. On a Streetfighter it sits in plain sight between the bars, which is why owners of these bikes tend to notice the standard barrel more than Panigale owners do. Replacing it with a flush anodised button is as much a visual change as a mechanical one — the 350 g is a bonus rather than the point.

Installation

The swap is a bench job. The original ignition block comes off its mounting, the JP KS DU021 goes on in its place, and the factory loom connector transfers across unchanged. The Key Box, holding the original key and wired to the immobiliser antenna, tucks away out of sight. Nothing is cut, so the bike can be put back to standard whenever it needs to be.

Fitment and Compatibility

  • Ducati Streetfighter V4 (2020–2024)
  • Ducati Streetfighter V4 S (2020–2024)
  • Ducati Streetfighter V4 SP (2020–2024)

Road Approval

None. Closed-circuit and competition use only. Fitting this switch to a road-registered Streetfighter makes that machine non-compliant.

Colour and Finish

Supplied in anodised black, the finish that reads as standard equipment on a Ducati rather than as an accessory. On a Streetfighter the switch is fully exposed between the bars, so the surface treatment gets looked at more than it would on a faired bike — anodising is integral to the alloy rather than a coating over it, which is why it holds its appearance where paint would wear through at the edges.
