DescriptionThe whole story

The JP KS YA067 answers the R9's ignition circuit with a button rather than a barrel, and leaves every other control on the motorcycle alone.

Key Features

  • Yamaha R9 (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 Triple Arrives

Yamaha finally put the CP3 into a faired chassis, and the R9 went into club racing before most dealers had one in the showroom.

Cut From Solid

Ergal machined rather than moulded, which is why the body survives the knocks a top yoke collects over a season of being wheeled about.

A Race Regulation Question

Some championships have rules about how the engine must be stoppable. Worth reading before ordering rather than at scrutineering.

A Sealed Unit

Everything electrical inside is closed against water and vibration, which is what separates this from a switch bought by the metre.

What Stays

Switchgear, starter button, lights and every rider aid. This part occupies the space the ignition block did and nothing else.

Two Fasteners

That is usually all that holds the block to the yoke. The care goes into the connector rather than into the mechanics.

The Number Is Modest

Three hundred and fifty grams. Nobody should buy this expecting a lap time, and everybody who has fitted one mentions the keyless operation first.

An Older Motorcycle

Barrels seize, keys wear and the switch pack inside eventually goes intermittent. On a machine already destined for a circuit, replacement is the moment to change approach.

Transport

A machine in a van with no ignition lock cannot be started by somebody leaning over the tailgate. It also cannot be locked, which cuts both ways.

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.
