DescriptionThe whole story

The naked version of Ducati's new 890 twin carries the same architecture as the Panigale V2 890 and the same JetPrime part number. JP KS DU066 replaces the ignition block on the 2025-on Streetfighter V2 and V2 S — and on a bike with no fairing, that change is on permanent display.

Key Features

  • For the Streetfighter V2 890 and V2 S 890, 2025–2026
  • Replaces the ignition block, key and lock
  • About 350 g saved at the steering head
  • Solid Ergal housing with an IP69K-sealed push button
  • Key Box supplied for the Ducati immobiliser
  • Plug-and-play using the factory connector

Not the 955

The 2022–2024 Streetfighter V2 955 takes a different part. Ducati's 2025 890 twin is a new motorcycle with a new loom, and the two switches are not interchangeable despite the shared model name. The frame plate settles it in seconds; the bodywork will not.

Everything on Show

A Streetfighter has no fairing, which puts the top yoke in the rider's line of sight and in every photograph of the bike. The standard barrel is the component up there that most obviously exists for a car park rather than for the road. An anodised Ergal button in its place changes what the cockpit looks like from the saddle, not just what it weighs.

Installation

The switch uses the Ducati mounting points and the factory ignition plug — no drilling, no splicing, no loom changes. The Key Box holding the original key connects to the immobiliser antenna and hides under the tank. Reversible in full, which matters on a bike this new.
