Engine & Performance

At the heart is a 799 cm³, 2-cylinder, 4-stroke, parallel twin with a 12.7 compression ratio, 88 mm / 3.46 " bore and 65.7 mm / 2.59 " stroke. Output is a healthy 70 kW / 94 hp and 87 Nm / 64.2 lb-ft, which translates to strong midrange drive for real-world conditions—threading city traffic, rolling on for highway passes, and carving up backroads. Bosch EMS with RBW gives precise throttle control, while the DKK Dellorto (Throttle body 46mm) setup and forced oil lubrication with 2 oil pumps help keep response consistent and the engine durable.

The 6-speed transmission works with a cable operated PASC slipper clutch to smooth hard downshifts and stabilize corner entries. Primary drive is 39:75 with a 16:41 secondary gear ratio, feeding a 520 X-Ring chain. Cooling is handled by a liquid cooled system with a water/oil heat exchanger, and the stainless steel primary and secondary silencer keep the package compact.

Practicality is baked in: fuel consumption is rated at 4.6 l/100 km / 1.22 gal/100 mi, and the 14 l / 3.7 gal tank means fewer stops on longer rides. CO2 emissions are listed at 108 g/km. The electric starter and 10 Ah battery capacity round out the everyday usability riders expect from a modern naked.

Handling, Comfort & KTM 790 Duke Seat Height

The chassis uses a Chromium-Molybdenum-Steel frame with the engine as a stressed element, powder coated for durability, plus an aluminium, powder-coated rear subframe. Suspension is WP APEX 43 up front and a WP APEX - Monoshock at the rear, with 140 mm / 5.51 " and 150 mm / 5.91 " of travel respectively. Geometry leans toward agility with a 1,475 mm / 58.07 " wheelbase and 66 ° steering head angle, while 186 mm / 7.32 " of ground clearance gives breathing room for rougher streets.

KTM 790 Duke seat height is 825 mm / 32.48 ". That height feels sporty without being extreme, giving most riders a balanced perch and good leverage. The KTM 790 Duke weight comes in at a wet 189 kg / 416.67 lb (dry 169 kg / 372.58 lb), which helps low-speed maneuvering and lane filtering feel light and predictable. Cast aluminium wheels (3.50 x 17", 5.50 x 17") and tyre dimensions of 120/70 and 180/55 provide confident contact patches and quick direction changes.

Equipment & Features

Braking hardware is serious for the class: up front, 2x radially mounted 4 piston caliper biting 300 mm / 11.81 " discs; at the rear, a single-piston floating calliper on a 240 mm / 9.45 " brake disc. The combination offers strong initial bite and good feel for spirited street riding.

• Bosch EMS with RBW
• Cable operated PASC slipper clutch
• 6-speed transmission
• Liquid cooled with water/oil heat exchanger
• Cast aluminium wheels with 120/70 and 180/55 tyres
