DescriptionThe whole story▼
The JP KS DU066 is what a Streetfighter V2 S 890 loses its ignition lock for: a plug-and-play switch cut from solid Ergal with an IP69K push button.
Key Features
- Ducati Streetfighter V2 S 890 (2025–2026)
- Replaces the original ignition block, key and lock
- Around 350 g off the top yoke
- CNC-machined from solid Ergal
- IP69K sealed push button
- Plug-and-play on the motorcycle's own connector
The New Naked Twin
The 890 engine under a wide bar, lighter than the machine it replaced and sharper with it. It is a track-day motorcycle sold as a road bike.
Three Hundred and Fifty Grams
That is the manufacturer's figure for what leaves the top yoke. It is a small number in a place where mass matters more than most.
Where the Weight Sits
High and forward, above the steering head. Mass in that position works against the rider on every direction change, which is why the figure is worth more than it looks.
Insurance and Theft
A bike without a steering lock is easier to move. That is a genuine consideration for anybody storing a machine outside a locked workshop.
Keeping the Barrel
It is the part an inspection or a buyer will ask for, and the part that costs real money to replace. A labelled bag solves it.
Regulations Vary
Some series require a specific stop control position or a lanyard. Nothing here prevents that, but it is worth confirming before the machine reaches scrutineering.
The Ignition Block Is Three Things
A lock, a switch and on newer machines an immobiliser aerial. Racing removes the reason for the first and the third, and this part covers the second.
Nothing About Performance
No power, no fuelling, no response. The only measurable change is the mass on the scales and the only felt change is at the fingertip.
What the Buyer Will Ask
Whether the original lock exists. A bike offered without it is a negotiation rather than a straightforward sale.
Made the Expensive Way
A body cut from solid Ergal, anodised rather than painted, a switch sealed to a rating written for industrial washdown, and a plate drawn for one motorcycle. None of that is necessary for a button and all of it is why this one lasts.
