KTM 890 Duke R

What exactly is the KTM 890 Duke R?

Born in 2020 as the radical evolution of the 790 Duke, the 890 Duke R carries KTM’s “Super Scalpel” nickname. The name fits perfectly: this is a precision instrument, not a sledgehammer. Its 889cc parallel twin produces 121 hp and 99 Nm — figures that won’t intimidate anyone on paper against larger roadsters. But stuff that engine into a bike weighing just 166 kg dry, and the power-to-weight ratio of 0.73 hp/kg puts it squarely in 600cc sportbike territory.

For 2024, the 890 Duke R stays true to the formula that made it popular since launch. KTM didn’t mess with the fundamentals, because there wasn’t much to fix. The model has been continuously refined since 2020, with notable input from former GP racer Jeremy McWilliams who helped develop the chassis. This is the final evolution of the LC8c platform before the 990 Duke takes over in displacement, though without the R’s radical edge.

What’s the engine like in daily use?

The LC8c twin is one of the best parallel twins in the business. Its 270-degree firing order (uneven, like a V-twin) gives it a character and soundtrack that regular-firing twins simply don’t have. The exhaust note is gruff and almost gravelly at low revs, transforming into an angry snarl as you approach 9,000 rpm. It pulls strong from the mid-range and spins eagerly to the redline.

Compared to the 790 it evolved from, the engine received a larger bore and stroke (90.7 x 68.8 mm), compression bumped to 13.5:1, bigger valves (37 mm intake, 30 mm exhaust), and a more aggressive camshaft profile. The crankshaft is 20% heavier, improving low-rpm smoothness and cornering stability. Lightened forged pistons partially offset this extra rotating mass. The ride-by-wire mapping (managed by a dedicated Dell’Orto ECU with individual manifold pressure sensors per cylinder) is excellent: throttle response is smooth and predictable across all riding modes.

In concrete terms, the 0-100 km/h sprint takes roughly 3.3 seconds, and the quarter mile falls in 11 seconds flat at 207 km/h terminal speed. That’s seriously quick for a mid-size naked. But it’s the roll-on acceleration from 80 to 160 km/h that really impresses: in third or fourth gear, you have instant cavalry under your right hand.

Fair warning: the bike ships with three modes (Rain, Street, Sport). Unlocking Track mode, the bidirectional quickshifter, engine brake control (MSR), and launch control requires purchasing the optional Tech Pack. This is the main sticking point for reviewers: at this price, those features should be standard. Especially since the cheaper 790 Duke gets them out of the box.

How good is the chassis?

This is where the 890 Duke R truly earns its keep. The tubular chrome-moly steel trellis frame uses the engine as a stressed member, gaining rigidity while saving weight. The cast aluminium subframe doubles as the airbox housing — no additional plastic covers or brackets, everything integrated into two connected pieces. The short wheelbase (1,482 mm) and aggressive steering geometry (65.7-degree head angle) make the bike extraordinarily quick to turn in.

The fully adjustable WP APEX suspension is top-tier kit for this segment: 43 mm inverted fork with split-function compression and rebound damping, rear shock with hydraulic preload, high and low speed compression, and rebound. Suspension travel is 140 mm front, 150 mm rear — enough to absorb road imperfections without sacrificing high-speed stability. The lightweight alloy wheels (finished in signature R orange) reduce unsprung mass and improve turn-in response.

On bumpy backroads, the 890 R stays planted and confidence-inspiring. On track, it allows committed riding without showing any weakness. This dual personality is what impresses the press most: many bikes that work well on the road go soft on circuit, and vice versa. The 890 R does both.

The Brembo Stylema brakes with MCS radial master cylinder (with adjustable lever ratio!) are borrowed from the 1290 Super Duke R. Feel is exceptional, modulation precise, and power more than adequate for track use. The MCS master cylinder lets you adjust the lever ratio — and therefore the brake feel — between progressive and aggressive. The Bosch 9.1 MP Cornering ABS with 6-axis IMU provides an intelligent safety net that accounts for lean angle. Supermoto mode disables the rear ABS for those who enjoy controlled slides.

Who is it for?

The 890 Duke R clearly targets sporty riders who want to have fun on backroads and occasional track days. Its tall seat (834 mm), committed riding position, and complete lack of wind protection make it poorly suited for long highway stints. Passenger comfort is virtually non-existent — the single-seat cowl comes standard, pillion pegs are optional through the PowerParts catalogue.

It’s also an excellent progression bike for riders stepping up from a 600cc or A2-class machine who want more power without jumping straight to an intimidating litre bike. The light weight and agility make the 121 hp very approachable.

If you want a versatile road/touring machine, the standard 890 Duke or even the 990 Duke would serve you better. But if you want the sharpest, most engaging naked in the mid-size segment, the R is hard to beat. Only the Triumph Street Triple RS can credibly challenge it, offering a more powerful triple-cylinder engine but in a slightly heavier package.

The bottom line

The KTM 890 Duke R 2024 remains one of the most rewarding machines in its class. It makes no effort to hide its sporting nature, and that’s precisely what makes it so addictive. Provided you’re willing to invest in the Tech Pack to fully unlock the electronics, you get a roadster capable of embarrassing much bigger and more expensive machines through the corners. The Super Scalpel still cuts deep.
