Ride Modes

The 2025 KTM 390 DUKE gives its pilots a selection of RIDE Modes to best suit whatever conditions they find themselves in. With STREET Mode activated as standard, this unleashes all the KTM 390 DUKE's fury, while RAIN Mode works to keep things a little more controlled in the wet.

Track Screen

TRACK Screen transforms the 5" TFT display graphics to be more race-focused, enlarging the rev counter, showing the laptimer, selected gear display, reduces the size of the speed readout, and shows preferred rider aid settings. What's more, TRACK Screen also allows riders to initiate Launch Control.

Frame

The design features a 2-piece construction composed of a steel trellis main frame with a pressure die-cast aluminum subframe. The rear shock absorber is mounted off-center to allow for the large airbox which allows for the lower seat height and, at the same time, adding to the DUKE's aggressive stance. Not only designed for looks, the primary objective of the frame design is to enhance vehicle dynamics by augmenting torsional rigidity, nimble agility, and enhanced feedback from the chassis.

CURVED PIVOT

Swingarm

A curved cast aluminum swingarm provides a sturdy and durable platform for the rear suspension system, featuring a direct shock absorber mount that is offset to the side, for that super-racy look. This also creates additional space for the new exhaust muffler, providing added attitude.

Fork

Upfront, a 43 mm WP APEX open cartridge fork with 150 mm travel keeps things in check, with adjustable compression and rebound settings.

Rear Shock

On the rear, you'll find an off-center WP APEX Separate piston shock absorber with 150 mm of travel and 60 mm of stroke. Rebound is easily adjusted with a 5-step clicker, and is also preload adjustable.

Wheels and Tires

Reducing weight where it counts the most, the 2025 KTM 390 DUKE's rims are wrapped in grippy Michelin Power 6 tires. This not only improves the overall handling characteristics but also means quicker turn-in and less strain on working components like axels and bearings.

Brakes

On the front wheel, the KTM 390 DUKE boasts a 320 mm brake disk with four-piston radial calipers. The design includes large disks to reduce the operating temperature with improvements in the resistance to fading and longer pad lifespan. On the rear wheel, a 240 mm brake disk is installed with a single-piston caliper which carries the same benefits as the front wheel. Cornering ABS and SUPERMOTO ABS are also standard features.
