DescriptionThe whole story

The JP ES KIT16 deletes the 1090 Adventure's air injection system in full, with both halves supplied together.

Key Features

  • KTM 1090 Adventure (2017–2019)
  • Both halves of the air injection deletion
  • Solenoid eliminator plus the head plugs
  • One part number, one fitting session
  • No drilling and no splicing
  • Every standard part refits afterwards

What Arrives

A pre-wired connector for the monitored circuit and two billet plugs for the cylinder heads. Between them they account for the entire system.

Half a Job Is Worse Than None

Cap the heads and the dashboard complains. Silence the solenoid and the ports stay open, so a cracked reed can still send exhaust gas towards the airbox.

One Session

Both parts on the bench means the tank comes off once. That is the practical argument for the kit and it is the only one that matters on a Sunday.

Ride Modes

The 1090 carries several throttle maps and switchable traction control. It is a considerably more sophisticated motorcycle than the entry position in the range suggests.

Eight Hundred and Fifty Millimetres

Seat height on the standard bike, which is manageable for most riders. KTM kept the adventure geometry without making the model impossible to get a foot down on.

The Sequence

Tank off, hoses free, housings off, plugs in, connector last. Nothing on that list needs a tool worth naming.

Both Heads

The LC8 V-twin carries the reed arrangement twice, so the kit includes two plugs rather than one.

Nothing Drilled or Spliced

KTM's own connector and fastener positions. The loom and the cylinder heads are left exactly as the factory built them.

Before Any Mapping

Air entering the exhaust after combustion corrupts gas analysis, so the deletion belongs before the dyno rather than after it.

Homologation

Removing emissions hardware ends road legality throughout Europe.

Nothing Replaced It

KTM dropped the 1090 when the 790 arrived from below and the 1290 covered everything above, and the gap it left has never been filled. A hundred and twenty-five horsepower with a nineteen inch front and no electronics anybody has to learn turned out to be a combination the company simply stopped building, which is why owners hold on to them.
