2021 KTM 890 Duke R

THE SUPER SCALPEL

Still agile, but with more punch, the KTM 890 DUKE R takes all the things we love about the KTM 790 DUKE and turns it up to 11. This is a no-compromise mid-weight naked bike, equally at home on mountain roads as it is on the race track, delivering more power, more torque and more Dukeness than any parallel twin that has come before.

Featurs may include:

Engine

• Developed from the same parallel twin that powers the KTM 790 DUKE, the KTM 890 DUKE R engine has been worked into a fire-breathing, high-performance midweight titan. With its increased bore and stroke, higher compression and higher max. RPM limit, the KTM 890 DUKE R churns out an impressive new level of horsepower and torque.

Engine case

• The KTM 890 DUKE R features horizontally split, high pressure cast aluminum crankcases, allowing for reduced wall thickness and weight. A heavier crankshaft and flywheel setup also helps to pump up torque.

Injectors

• Developed specifically for KTM by DELL'ORTO, new sensors in each throttle body measure the manifold pressure and adjust the mixture accordingly per cylinder, improving throttle response and smoothing out throttle action for more precise throttle inputs.

Cylinder heads

• A new cylinder head has been developed specifically for the KTM 890 DUKE R to accommodate a set of larger 37 mm intake and 30 mm exhaust valves, while the camshafts feature increased lift and a more aggressive profile. A new balancer shaft has also been added to match the increased RPM and increased rotating mass.

PASC clutch

• The slipper clutch allows riders to enter corners confidently without locking up the rear wheel under hard deceleration or when downshifting, while remaining feather-light on the clutch finger.

Ride-by-wire

• Ride-by-wire processes throttle inputs with the help of electronic sensors and activates the throttle valves, electronically translating the throttle commands of the rider into the best throttle valve positions for the current riding situation. All this means more control when attacking the twisties.

Crankcase

• The KTM 890 DUKE R features horizontally split crankcases, made from high-pressure cast aluminum, allowing for thinner wall thickness and added weight saving. The crankcases on the KTM 890 DUKE R have also been re-engineered to allow for the longer stroke over the KTM 790 DUKE.

Pistons

• Two forged box pistons featuring three piston rings and a bronze conrod bearing work in tandem to power the beating heart of the KTM 890 DUKE R. Thanks to the box construction, piston weight is reduced by 10 grams compared to the pistons in the KTM 790 DUKE engine, despite the larger bore.

Exhaust

• A stainless-steel thing of beauty. The middle damper centralizes mass and allows for a relatively small muffler that plays a dramatic soundtrack. Hundreds of test bench runs and complex simulations ensured that this exhaust system contributes decisively to the tractable torque curve and excellent emission standards.

Frame

• Just like the KTM 790 DUKE, the KTM 890 DUKE R's handling characteristics are thanks to the dynamic, loadbearing design of the tubular chassis, which allows it to carve through twisty tracks and mountain passes with extreme responsiveness. Just like every other KTM R, the frame is painted orange to highlight its sporty credentials.

Subframe

• The subframe is cast aluminum and houses the airbox. No plastic covers, no additional brackets - everything is cast into two connected pieces to reduce complexity and weight. The triangular shapes in the subframe allow for a stronger, stiffer construction.

Swingarm

• The die-cast, open-lattice swingarm is optimized for stiffness but features a steeper angle for increased stability as well as excellent flex characteristics. This makes the KTM 890 DUKE R every bit as sharp as you'd expect it to be.

Suspension

• Adapted to suit the added power of the KTM 890 DUKE R but still retaining the signature DUKE agility, the adjustable suspension on the KTM 890 DUKE R has been fettled to be sportier with improved high-speed stability, while retaining real-world street riding comfort.

Front fork

• The KTM 890 DUKE R features adjustable linear spring WP APEX front forks with split function damping, compression and rebound settings. This allows riders to perfectly sharpen their preferred setup for track or the street.

Triple Clamps

• Triple clamp stiffness has been tuned to match the flex of the fork, contributing to sporty handling and excellent feedback. An aluminum steering stem has been used instead of steel, as on the KTM 790 DUKE, to reduce the overall weight.

Rear shock

• A fully adjustable WP APEX shock takes command at the rear of the bike, with high and low speed compression settings, as well as rebound adjustment. A hydraulically adjustable preload adjuster allows for quick and easy tuning on the fly.

Wheels

• The KTM 890 DUKE R comes with extremely lightweight, light-alloy wheels finished i
