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 engine that’s in the 890 Adventure R, but with a different tune, more for power, making a peak of 89 kW (119 hp) at 9250 rpm.

KTM 890 Duke R Service Intervals

Overall, the service intervals for the KTM 890 Duke R are 15,000 km (9,300 mi) or every year. At every service, you change the oil and filter, and do a host of other checks per the schedule below.

The major service (valve service & new plugs) is every two 30,000 km / 18600 miles.

Since the Duke R has a chain drive, you also need to regularly maintain the chain — keeping it clean and lubricated, and adjusting the tension.

Finally, make sure to regularly refresh fluids, including coolant and brake fluid.

Maintenance Schedule for the KTM 890 Duke R

Below is the maintenance schedule for the KTM 890 Duke, adapted from the manual.

The original maintenance schedule was broken up into “required” and “recommended” maintenance. But this never made sense as much of the recommended stuff was required by other manufacturers. KTM later combined them.

For convenience and to avoid repetition, we’ve separated out a list of checks to be done at every service.

Maintenance Schedule


  • After the end of the service schedule, keep repeating it in this pattern.

Chain Maintenance

Regularly clean and lubricate your KTM 890 Duke R’s chain. KTM doesn’t specifically recommend how often you do this, but general consensus is usually around 500 miles / 800 km, or after riding in the rain or dirty conditions. Use Motorex Chain Cleaner or Motul Chain Cleaner.

To check chain condition, measure the distance along 18 chain pins (first one is 1, last one is 18) with the chain taut (pulling on the chain with a 15 kg / 33 lb weight). The distance should not exceed 272 mm / 10.71 inches. If it does, replace the chain as well as the sprockets.

Checking chain slack

To check chain slack on your KTM 890 Duke R, follow these steps.

  1. Put the motorcycle in neutral and on a flat surface.
  2. Elevate the rear of the motorcycle.
  3. Find the chain sliding piece.
  4. At 2.5 cm / 1 inch from the chain sliding piece, push the chain up towards the chain sliding piece.
  5. Measure from the flat part of the swingarm directly above the chain to the chain. This is the chain tension

Target chain tension (distance from swingarm when pushed up per the guideline): 2-5mm (0.08-0.2 inches)

If the chain slack is out of spec, you need to adjust the chain tension.

Adjusting chain slack / tension

To adjust the chain slack on the KTM 890 Duke R, follow the steps below. As with measuring chain slack, make sure that the motorcycle is on a level surface on its kickstand, in neutral, with no weight on it (no saddlebags / luggage), and elevate the rear wheel.

  1. Loosen the rear axle and the adjuster lock nuts on either side of the axle.
  2. Turn the adjuster nuts to tighten (or loosen) the chain. Keep checking the chain tension to see if it has come within spec.
  3. Keep an eye on the adjuster alignment reference marks on either side of the axle. Make sure that the adjustment is to the same point.
  4. When you’re done, tighten the axle to 90 Nm / 66 lb-ft.
  5. Re-check the chain slack again to make sure it’s still within spec.
  6. Lower the rear wheel and check chain tension again.

About the KTM 890 Duke R

KTM 890 Duke R 2020 2021 studio

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

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

Unlike naked sport bikes from many manufacturers, the 890 Duke R is not based on a superbike with fairings of any kind. So whether you’re after a daily scratcher or a track weapon, the 890 Duke R is your only port of call in the class!

The 890 Duke R continues the same spirit of the “middleweight” KTM Duke motorcycles. It’s a lower-weight, lower-power, but still very high-spec alternative to 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. In later years, KTM re-released the 790 Duke as a lower-cost alternative to the 890.

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
Front brakesKTM brake calipers, 300 mm discsBrembo Stylema calipers, 320mm discs
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

You basically get a lot more bang for your buck in the 890 Duke R. You get a lot more bang, period!
