TAKE A SEAT
Seat
Improved comfort for the rider and pillion, thanks to thick seat foam, a narrow profile, and an overall excellent performance in ergonomics. Need for more or less seat height? The KTM 125 DUKE has a standard seat height of 800 mm, but can easy be increased to 820 mm with the optional KTM PowerParts seat offering.

04. ALL-IN AGILITY
THE BACKBONE
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.
SPRING INTO ACTION
Fork
Upfront, a 43 mm WP APEX open cartridge fork with 150 mm travel keeps things in check, ensuring rock-solid performance on all street conditions.
MAX TRACTION
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. The rear shock is also preload adjustable.
ROLLING THUNDER
Wheels and Tires
Reducing weight where it counts the most, the KTM 125 DUKE has made significant inroads at reducing unsprung mass thanks to a set of lightweight wheels and grippy Michelin Road 5 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.
STOPPING POWER
Brakes
On the front wheel, the KTM 125 DUKE boasts a 320 mm brake disk with a four-piston radial calipers. The design includes bigger 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.
