The KTM ?8?90 DUKE ?redefines the word ‘sharp’ by adding an extra edge. Powered by an 889 cc parallel-twin nestled into one of the lightest and most compact chassis around, the KTM 890 DUKE boasts the agility you’d expect from a 600 cc?, ?but with the ?meaty punch of a bigger twin. ?It doesn’t rewrite the mid-sized naked bike rule book. It obliterates it.
The LC8c engine shares a great deal of its ferocity with the ultra-sharp KTM 890 DUKE R. Boasting a hard-hitting 115 Hp and 92 Nm, this compact, liquid-cooled 8 valve powerplant, is the most compact twin in class punching way above its weight in terms of output.
The 8 valve DOHC cylinder head contains twin chain-driven camshafts and one spark plug per cylinder. Additionally, the camshafts in the KTM 890 DUKE are assembled, which makes them even lighter than forged camshafts. DLC coated finger followers, steel valves and a hydraulic chain tensioner complete the cylinder head assembly.
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.
Instead of the electronic injection system’s throttle valves being controlled by cables, ride-by-wire processes throttle twist grip movements with the help of electronic sensors and activates the throttle valves accordingly using servo motors. However, our ride-by-wire on the KTM 890 DUKE goes the extra mile: It electronically translates the throttle commands of the rider into the best throttle valve positions for the current riding situation. The new logic of the engine mapping automatically adjusts the fueling per cylinder. Choking, jolting and involuntary wheelies are a thing of the past. Voluntary ones, however, could easily be a thing of your future.
The incredible handling characteristics of the KTM 890 DUKE are founded on the dynamic, loadbearing design of the tubular chassis. Engineers had one goal in mind, and that was to keep the chassis as rigid and compact as possible for sharper turn-in and greater lean angles, allowing it to slice through the turns with extreme responsiveness.
The KTM 890 DUKE boasts a WP suspension package which has been specifically developed to get the most of the power output and handling characteristics, with a dedicated factory setting, new springs, and additional base valve fittings in the front fork.
A set of WP APEX 43mm open cartridge upside-down forks take care of things up front, making use of split function technology. The front fork also adopts new linear springs which are not only lighter but also guarantee a more intuitive feel, while the added base valve improves high-speed damping.
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.
The KTM 890 DUKE is fitted with extremely lightweight, light-alloy wheels manufactured in a low-pressure die casting process. Not only do the lightweight wheels make the bike lighter overall, they also minimize the unsprung masses and moment of inertia, with a positive impact on the handling and ride dynamics.
The KTM 890 DUKE is fitted with Continental ContiRoad rubber as standard. These feature ultra-fast warm-up technology, which boasts improved wet weather grip, increased durability, and stability, and offer natural, easy handling on all road surfaces.
Maximum deceleration is ensured at the front wheel on the KTM 890 DUKE by two radially mounted four-piston fixed calipers, revised brake pads and two 300 mm discs. The rear brake features a single disc and a single-piston floating caliper. All this stopping power is supported by KTM’s Cornering ABS.
Like all pilots, DUKE riders need easy access to information. In that regard, the KTM 890 DUKE features an intuitive multicolor, light variable TFT dashboard. Best of all, as the revs rise, the display bars change color to indicate when to shift, either spurring you on or warning you that the engine is too still cold for flat-out backroad attacks.
The KTM 890 DUKE has adopted a vast swathe of rider aids found on the blistering KTM 890 DUKE R, and further refined them to be more user and road-friendly, without hindering any performance.
Riders can choose from four ride modes, namely: SPORT MODE for more aggressive riding, STREET MODE for comfortable urban riding, RAIN MODE for when things get a little slippery, and the optional ultimate attack mode – TRACK MODE. This gives KTM 890 DUKE pilots full power output, the ability to dial down the traction control, smooth out the throttle, and switch off the anti-wheelie for rear wheel antics.
The KTM 890 DUKE boasts a collection of advanced electronic wizardry which rivals some top-end sportbikes. Most crucially, is lean-angle sensitive Cornering MTC (Cornering Motorcycle Traction control), which reduces engine output at the faintest hint of wheel slip. This is done in an extremely smooth, barely perceptible interference allowing the rider to simply get on with the ride with complete confidence. Depending on the selected ride mode, Cornering MTC also allows for several levels of traction slip at the rear wheel for more spirited riding styles. And for the daredevils, we give you: the off-switch!
A key component of the comprehensive BOSCH MSC assistance package is the lean-sensitive cornering ABS. In a nutshell, this means riders have increased confidence during hard braking, even at extreme lean angles.
