KTM 890 Duke R (2020+) Maintenance Schedule and Service Intervals

This is the maintenance schedule and service intervals for the KTM 890 Duke R, announced at EICMA 2019 for the 2020 model year. (Originally it was announced for 2021, but KTM brought it forward.)

The KTM 890 Duke R is the sportier (and slightly more expensive) sibling to the KTM 890 Duke, though the 890 Duke R was actually announced first.

The KTM 890 Duke R is part of the 890 series of motorcycles. It’s based on the same 889cc DOHC liquid-cooled parallel twin as in the 890 Adventure R, but is tuned differently, more for power, making a peak of 89 kW (119 hp) at 9250 rpm.

About the KTM 890 Duke

KTM 890 Duke R 2020 2021 studio

The KTM 890 Duke R is KTM’s premium middleweight standard sportbike.

It’s definitely a sportbike, but with handlebars, making it a sportbike that’s much more usable every day, like the Yamaha MT-09 SP for example.

The 890 Duke R continues the same spirit of the “middleweight” KTM Duke motorcycles. They’re a lower-weight, lower-power, but still very high-spec an alternative the trailblazing Super Duke R.

In no way should you consider the 890 Duke R to be a “beginner” version of the SDR, other than that it’s not quite as extreme.

The KTM 890 Duke R replaces the KTM 790 Duke (which never got an R version), which was already a game-changer for KTM (two pistons in a Duke, rather than just one!). But the 890 R takes it a step further.

The KTM 890 Duke R was announced and released earlier than the standard 890 Duke, perhaps to ease the pain of 790 Duke buyers who had only recently made their commitments.

Here’s what the 890 Duke R gets on top of the 890 Duke (standard, non-R):

Spec890 Duke890 Duke R
Peak power86 kW (115 hp) @ 10500 rpm89 kW (119 hp) @ 9250 rpm
Peak torque92 Nm (68 lb-ft) @ 8000 rpm99 Nm (79 lb-ft) @ 7750 rpm
SuspensionWP Apex suspension front and rear, with only preload adjustability in the rearWP Apex Pro suspension with full adjustability

TyresContinental ContiRoadMichelin Power Cup 2
HandlingLower ground clearance, lean angle, and seat height. More relaxed rider triangleHigher ground clearance, more lean angle, higher seat, more aggressive rider triangle
