DescriptionThe whole story

The JP ES 046 replaces the Super Duke GT's reed housings with billet plugs sealed on O-rings.

Key Features

  • KTM 1290 Superduke GT (2016–2024)
  • 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 Physical Half

Reed assemblies on both cylinder heads with hoses from the airbox. Deleting the solenoid electrically leaves every one of them bolted in place.

Cruise Control

Fitted from the first model year and operated from the left bar. On a motorcycle capable of covering a country in a day it is used constantly.

What Goes Wrong With Reeds

They crack after enough heat cycles and then pass exhaust gas back towards the airbox. The residue is obvious and the cause rarely is.

Turned From Solid

A billet plug with an O-ring in a machined groove. Nothing inside it ages and nothing needs checking again.

Two Heads

The LC8 carries the arrangement twice. Both sides have to be capped for the deletion to be complete.

Pannier Mounts in the Subframe

KTM designed the mounting points into the frame rather than bolting a rack on afterwards. It keeps the cases narrow and the bike usable in traffic.

Before Any Fuelling Work

Air entering the exhaust after combustion corrupts gas analysis, and a GT is remapped more often than a touring bike ought to be.

Original Fasteners

KTM's own positions and torque figures. Nothing is drilled and the casting is untouched.

The Electrical Side

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

Type Approval

The system belongs to the approval and removing it ends road legality in Europe.

A Tourer With No Manners

KTM's answer to the sport touring class was to leave the engine alone and add a fairing, and the result behaves nothing like its rivals. It will carry a passenger and hard cases across a country and then embarrass a superbike on the road at the end of it.
