DescriptionThe whole story▼
The JP ES 046 replaces the 1090 Adventure's reed housings with billet plugs sealed on O-rings.
Key Features
- KTM 1090 Adventure (2017–2019)
- Caps the air injection port in the head
- Turned from solid billet
- Sealed with an O-ring, no jointing compound
- Uses KTM's own fastener positions
- Standard housing refits at any time
The Mechanical Side
Two reed housings, two hoses and a set of clips. Disconnecting the solenoid electrically leaves every one of them still bolted to the engine.
Why Cap Rather Than Plug
Workshops improvise with a bolt and a washer or with epoxy. Neither holds its seal through a season of heat cycling; a turned plug on an O-ring does.
Ride by Wire
The 1090 uses an electronic throttle with several ride modes. It also means the fuelling is entirely software, which is why honest exhaust readings matter before anyone changes it.
A Hundred and Twenty-Five Horsepower
KTM gave the entry adventure bike most of the power the 1050 detune had removed. It made the model considerably easier to recommend.
What Comes Off
Housings, hoses and brackets. On a bike ridden on rough ground that is several fewer items to work loose or tear away.
Heat and Vibration
Plastic bolted to a cylinder head takes more thermal movement than almost anything else on the motorcycle. Aluminium is indifferent to it.
Both Cylinders
The V-twin carries the arrangement twice. Closing one side and leaving the other achieves very little.
Nothing Drilled
KTM's own fastener positions and torque figures throughout. The head is not modified in any way an inspection would find.
The Solenoid Remains
Its circuit is watched by the controller independently. Only the electrical eliminator keeps the warning off the display.
Type Approval
Removing emissions hardware ends road legality in every European market.
A Range That Reorganised Around It
KTM discontinued the 1090 when the 790 arrived from below and the 1290 covered everything above. Nothing directly replaced it, which is why the model still has a following: a hundred and twenty-five horsepower and a nineteen inch front turned out to be a combination the company never rebuilt.
