KTM Duke and Super Duke Suspension Guide: Mupo Options by Model

KTM's Duke Range: Genuine Mupo Coverage

KTM's Duke and Super Duke lineup spans from the accessible 125 to the fire-breathing 1290 Super Duke R, all sharing KTM's DNA of light weight and sharp handling. Mupo, the Italian suspension specialist, has real and fairly extensive coverage across this range — here's exactly what we stock.

KTM 1290 Super Duke R

  • Mupo AM1-S01 steering damper (2014–2017) — around £335. A progressive rotary damper that controls headshake without adding unwanted steering resistance at low speed.
  • Mupo fork cartridge kit K911 (25mm pistons) (2014–2017) — around £1,110, replacing the OEM cartridge internals for fully adjustable damping.
  • Mupo AB1-Evo Factory rear shock (2014–2017) — around £1,060, and the standard AB1-Evo rear shock at around £865.

KTM RC8 / RC8-R (1190)

  • Mupo fork cartridge kit K911 (25mm pistons) (2009–2016) — around £1,110
  • Mupo R-EVOlution fork cartridge springs kit (2009–2016) — around £865, a lower-cost alternative that upgrades springs within the existing cartridge
  • Mupo AB1-Evo rear shock (2009–2016) — around £865

KTM Duke 125, 390 and 690

  • Mupo R-EVOlution fork cartridge springs kit — confirmed for Duke 390 and Duke 690 (2012–2016) — around £865 each
  • Mupo GT1 rear shock — confirmed for Duke 125 (2010–2012), Duke 390 (2012–2016), and Duke 990 (2009–2013) — around £515 each. The GT1 is a pressurised, fully rebuildable shock with internal floating piston.

KTM 790 / 890 Duke

We do not currently have confirmed Mupo products for the 790 or 890 Duke platform in our verified catalogue. If you ride one of these and want a suspension upgrade, email us and we'll confirm current availability honestly rather than list something unverified.

Choosing Between a Fork Cartridge Kit and a Springs Kit

Where both are available for your model, the full K911 cartridge kit replaces the internal damping hardware entirely and gives the widest adjustment range — it's the track-focused choice. The R-EVOlution springs kit upgrades spring rate within your existing cartridge at roughly 20% less cost, a sensible mid-point for road riders who want better support without a full internals swap.

Setting Sag First

Before committing to any hardware upgrade, confirm your static sag is set correctly for your weight — 35mm front, 30mm rear is a reasonable starting point for a 75kg rider on most Duke models. Many riders who think they need new suspension actually have incorrectly set factory suspension.
