DescriptionThe whole story▼

A naked 889 cc machine like the 890 DUKE R puts its engine cases in the firing line. The STEKT204 weighs 850 g and spends most of that on a damped three-material stack rather than one solid block. LighTech supplies it for the 890 DUKE R complete, so no separate hardware order is needed.

Key Features

  • Aluminium upper ring for surface hardness where the 890 DUKE R actually touches down
  • LighTech part number STEKT204, catalogued for the KTM 890 DUKE R
  • Designed around the 890 DUKE R specifically rather than adapted from another model
  • What the STEKT204 absorbs never reaches the 890 DUKE R frame at all
  • Magnesium base keeps the overhung mass off the 890 DUKE R frame boss
  • No type-approval paperwork supplied with the STEKT204 — see the approval note below
  • Three materials, three jobs across 850 g: hard outside, light in the middle, soft at the core

Why a Damped Slider

The useful question is not how hard the STEKT204 is, but what the 890 DUKE R frame sees afterwards. Between the aluminium and the frame of the 890 DUKE R sits a rubber element that is meant to move. At the speeds where this matters, that is the difference between a scuff and a workshop bill.

Construction and Material Quality

Aluminium gives the STEKT204 ring the surface hardness a slide demands. Behind it, a magnesium bush and a magnesium base keep weight off the 890 DUKE R frame mount. The nylon shell is the sacrificial surface: it scuffs first and costs least to renew.

Fitment

Fitment is the KTM 890 DUKE R, 2020 to 2026. No modification to the 890 DUKE R is involved — the standard points take the kit.

In the Workshop

The 850 g of the STEKT204 arrive as one boxed kit for the 890 DUKE R. Leave the final torque until the position is confirmed on the 890 DUKE R. Black is the only finish LighTech makes the STEKT204 in.

Supplied As

The STEKT204 box holds two sliders, the pins and the spacers the 890 DUKE R frame bosses need. LighTech keeps the STEKT204 in its spare parts programme rather than treating it as disposable.

Road Approval

Nothing in the STEKT204 box constitutes a type approval, and we do not imply one. Rules differ by country; in Germany the 890 DUKE R inspection is where this comes up. Ask before you fit it if the bike is registered. Track days and paddock use are unaffected.
