DescriptionThe whole story

The R9 is Yamaha's CP3-powered sportbike, and it arrived in 2025 into a market where almost nobody launches a new supersport machine. JP KS YA067 is the JetPrime kill switch cut for it — a new part number for a new platform.

Key Features

  • Built for the Yamaha R9, 2025–2026
  • Replaces the ignition block, barrel and key outright
  • About 350 g removed from the steering head
  • Solid-machined Ergal housing, anodised black
  • IP69K-sealed push button
  • Key Box included for the Yamaha immobiliser

A New Platform, Not a CP2 Carry-Over

The R9 uses the three-cylinder CP3 engine and its own loom, so it does not share the switch that covers the R7, MT-07 and Ténéré 700. If you have been looking under those part numbers, this is why the R9 is not there. It is worth checking, because the two families are easy to conflate in a Yamaha catalogue.

Weight at the Front

Yamaha built the R9 around a light aluminium frame and made a point of the mass figures. The ignition assembly is one of the few remaining items on the bike that was specified for road convenience rather than for weight, and it sits in the worst possible place — above the roll axis and ahead of the steering axis, where mass resists direction changes twice over.

Installation

Standard mounting points, factory ignition connector, nothing drilled or spliced. The Key Box holding the original key connects to the immobiliser antenna and tucks out of sight. The job is reversible in full, which on a motorcycle this new and this early in its life is a genuine consideration.
