DescriptionThe whole story

The JP KS YA023 is what a R1 loses its ignition lock for: a plug-and-play switch cut from solid Ergal with an IP69K push button.

Key Features

  • Yamaha R1 (2004–2024)
  • 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

With the Race Kit Harness

A machine wired for Yamaha's own race kit expects a different ignition arrangement, and JetPrime lists a separate switch for those bikes.

Reversible

The standard block refits on its own fasteners with its own connector. Keeping it in a labelled bag is the whole of the requirement.

What the Original Block Is

A lock barrel, a switch pack and on modern bikes an immobiliser aerial, all in one casting bolted through the top yoke.

Vibration

A button on a yoke sees more of it than one on a handlebar. The body is machined and the switch is sealed for that reason.

The Push Button Itself

Sealed to IP69K, which is the rating for high-pressure hot-water washing. Motorcycles that live on trailers meet a lot of that.

Fitted Once

There is no service interval, nothing to lubricate and nothing to adjust. The switch is sealed and the body does not wear.

The Button's Feel

Positive, sealed and usable in gloves. It is the one part of the design a rider actually interacts with, which is why the switch is the expensive component.

Tools

Hex keys and a torque wrench that reads accurately at low settings. Nothing specialised and nothing expensive.

A Cockpit Without a Keyhole

The top yoke is the part of the motorcycle a rider looks at most. Removing the barrel changes it more than any sticker ever will.

Keeping the Motorcycle Reversible

Nothing is cut, drilled or soldered. The standard block refits on its own fasteners with its own connector in about the time it took to remove. Keep the barrel and its key together in a labelled bag, because a barrel without a key is worth nothing.
