DescriptionThe whole story

KTM's 190-horsepower naked keeps its engine as exposed as ever, and the PAIR covers sit right where the eye goes. JP ES 046 replaces them with machined plates and plugs the airbox behind them.

Key Features

  • For the 1390 Super Duke, R and R Evo, 2024–2026
  • Billet aluminium covers for both cylinder heads
  • Airbox spigot plug included
  • Original fasteners and sealing faces
  • Mechanical half of the PAIR delete
  • Carried over from the 1290 — same part number

Why Billet Rather Than Cast

The plates seal against a hot head under bolt load. A machined billet plate holds its flatness there, which is what stops it weeping after a season of heat cycles. Cast or pressed parts distort more readily under the same conditions — and on a Super Duke, a weeping plate is visible as well as untidy.

Torque, Not Enthusiasm

These bolt into aluminium. The thread in the head will give up long before the fastener does, so a moderate torque is the right one. Clean the mating face back properly first: the original gasket surface usually carries a ring of baked-on residue that holds the plate off just enough to seep once everything is hot.

Fitting It

Covers off, valves out, faces cleaned, plates on. On a naked bike the access is better than on almost anything else in this range — no fairing to remove, and both heads reachable from the side.

Fitment and Compatibility

  • KTM 1390 Super Duke (2024–2026)
  • KTM 1390 Super Duke R (2024–2026)
  • KTM 1390 Super Duke R Evo (2024–2026)

Road Approval

None. Closed-circuit and competition use only.

Visible From Three Metres

There is no bodywork on a Super Duke, so a plate that sits proud, or one fitted with the anodising scratched, is obvious at a glance. Handle them with the same care as any other visible engine part and fit them last, after the sealing faces are clean and dry.
