DescriptionThe whole story▼
The last-generation R6 never really stopped racing, and a large number of the surviving bikes are US imports running US-specification looms. JP KS YA013 is the kill switch for those machines — the same idea as the European part, cut for a different ignition connector.
Key Features
- For US-version Yamaha R6, 2017 through 2025
- Replaces the ignition block, barrel and key entirely
- About 350 g saved at the top of the chassis
- Solid-machined Ergal housing, anodised black
- IP69K-rated push button
- Key Box supplied where the bike retains its immobiliser
US Wiring, Different Part
Yamaha's US-market R6 uses a different ignition circuit arrangement from the European bike. The switch body is the same; the harness end is not, and it cannot be adapted. If the R6 came into Europe as a grey import — and a great many of the track-only ones did — this is the part number to check against before ordering.
A Bike That Outlived Its Homologation
The R6 stopped being sold as a road bike in Europe but carried on as a race machine, which means most of the ones getting new parts today will never see a public road again. That makes a race-only kill switch an easy decision rather than a compromise: there is no road approval to lose on a bike that no longer has any.
Materials
Ergal is 7075 aluminium, machined here from solid rather than cast so the wall sections stay thin without giving up stiffness. The IP69K button is rated for close-range high-pressure hot-water cleaning — a harder test than a paddock jet wash, and a better standard than the open lock cylinder it replaces.
