DescriptionThe whole story▼

On the KTM 990 Duke R (2025–2026) the JP ACCGP KT016 swaps the standard ride-by-wire grip for a shorter-throw unit, milled from solid Ergal, that keeps the R's sharper fuelling map intact while asking considerably less of the wrist on the way to full throttle.

Key Features

  • KTM 990 Duke R (2025–2026)
  • GP Series ride-by-wire quick throttle with a sixty degree rotation angle
  • Progressive return spring, preload adjustable externally in three positions
  • CNC-machined from solid Ergal 7075
  • Plug-and-play on the motorcycle's own connector
  • Standard throttle assembly refits at any time

A Chassis Built for Commitment

The Duke R leans on firmer suspension and a more aggressive geometry than the base Duke, the kind of setup that rewards decisive throttle inputs rather than hesitant ones. A shorter rotation suits that character: the hand commits to an opening sooner and the engine responds exactly as quickly as the R's tuning intends.

Milled From One Block of Ergal

Rather than cast and finished, the housing starts as a solid billet of 7075 Ergal that is machined down to shape. The result holds its action after repeated hard use on track days, where the lever sees far more cycles per session than it would on a road-only bike.

A Reset the R Needs After Fitting

Once the new grip is on, the ride-by-wire control unit needs a short diagnostic procedure to relearn the throttle position sensor's range. Most dealers already set up for KTM electronics handle this in a few minutes, and the step matters more on a bike tuned as precisely as the R.

Exiting a Corner on the Duke R

Riders who push the 990 Duke R hard on a circuit tend to notice the shorter throw first on corner exit, where rolling the wrist the final few degrees under lean used to cost fractions of a second that now simply aren't spent.

Working With the Existing Switchgear

The unit is built to bolt onto the stock bar clamp and switch cluster without modification, so none of the Duke R's existing controls need to be relocated or rewired to make room for the shorter-throw mechanism, and the install stays within an afternoon rather than a full day in the garage.

If the Standard Feel Is Wanted Back

The original KTM throttle can be refitted at any time, which leaves an owner free to test the shorter rotation on a few track days before deciding whether to keep it on permanently, rather than committing to the change the first time the bike leaves the workshop.
