DescriptionThe whole story

The JP ES 046 caps the 1090 Adventure R's air injection ports with turned billet plugs.

Key Features

  • KTM 1090 Adventure R (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

What It Replaces

The reed housings on both cylinder heads, along with the hoses that feed them from the airbox. They are the physical half of the system.

Fewer Parts, Fewer Failures

Every hose, clip and plastic box above the engine is something a fall or a branch can find. On a bike ridden properly off road that matters more than the weight.

Crash Protection Is Standard Practice

Nobody rides an 1090 R off tarmac without bars and a sump guard. Reducing what sits above the engine is part of the same thinking.

Eight Hundred and Ninety Millimetres

Seat height on the R version, which rules it out for a lot of riders and is exactly right for the ones it suits. KTM did not compromise it.

O-Ring, Not Sealant

A rubber ring in a turned groove against a machined face. It comes apart cleanly years later with nothing to scrape off.

Both Sides

The LC8 V-twin carries the arrangement on each head. The deletion is only complete when both are capped.

Before Any Mapping

Air entering the exhaust after combustion makes gas analysis describe the plumbing rather than the engine. Serious fuelling work starts here.

Original Fasteners

KTM's own bolt positions and torque values. Nothing is drilled and no thread is cut.

The Electrical Half

The solenoid circuit is monitored separately and needs its own eliminator.

Homologation

The system is part of the approval; removing it makes the bike a competition machine in Europe.

Sought After Second Hand

The R version of a model that lasted three seasons was never going to be common, and demand has held prices up in a way the standard bike's have not. Riders who wanted a large adventure bike with real off-road geometry and no electronics they did not ask for keep looking for these.
