The KTM 390 Duke (2024+) has a 820 mm (32.3 in) seat height and a 1357 mm wheelbase. For an average 175 cm rider that works out to about 0° of forward lean with the knees bent to about 83°, and that rider can get the balls of both feet down. See the riding-position diagram above, and enter your own height and inseam to see your fit. The KTM 390 Duke (2024+) is LAMS-approved (learner-legal to ride in Australia).
The KTM 390 Duke (2024+) in the real world
The 390 Duke is the most aggressive-feeling ergonomics package in the small-naked class — a wide, tapered handlebar you sit right on top of, a firm and flat seat, and pegs set slightly back. You sit “in charge” of the bike rather than perched on it, and that upright-but-attacking stance is a huge part of the Duke’s character. At around 165 kg ready to ride, it also hides its seat height well.
That seat height is the number to take seriously: 820 mm is tall for a LAMS naked (an MT-03 sits 40 mm lower). The saving grace is that the Duke is razor-narrow between your legs, so much of the height comes back as usable reach. Riders around 170 cm typically end up on the balls of both feet — secure, but worth verifying against your own inseam above rather than assuming.
Who the 390 Duke fits
One of the roomier small bikes for taller riders — the wide bar and relatively generous seat-to-peg distance suit riders up to ~190 cm better than an R3 or Ninja 500.
Shorter riders shouldn’t rule it out on the 820 mm figure alone: the narrow waist helps noticeably, and the low weight makes a balls-of-feet stop unintimidating.
The seat is firm and flat — sporty riders like the freedom to move; commuters often call it hard after an hour.
The upright wide-bar stance keeps all the weight off your wrists — a good pick if faired LAMS bikes bother your hands.
Common fit & comfort changes
Factory lowering options — KTM’s accessory catalogue offers a lower seat and suspension lowering parts for the Duke family — the dealer-supported route for shorter riders, and worth pricing into the purchase.
Aftermarket comfort seat — Softer and often slightly taller foam addresses the firm stock perch and adds knee room for tall riders in one change.
Bar rotation / risers — The wide taper bar has usable adjustment in its clamps; rotating it back is free and changes the reach more than you’d expect.
Most of these can be previewed on your own body with the “Adjust the fit” sliders in the simulator above.
The KTM 390 Duke (2024+) has a seat height of 820 mm (32.3 inches).
Can a 175 cm rider flat-foot the KTM 390 Duke (2024+)?
On its 820 mm seat, a 175 cm rider (about 80 cm inseam) can typically get the balls of both feet down on the KTM 390 Duke (2024+). Taller or shorter riders differ — use the simulator to check your own ground reach.
What is the riding position of the KTM 390 Duke (2024+)?
For an average 175 cm rider, the KTM 390 Duke (2024+) riding position (also called the seating position) works out to about 0° of forward lean with a 83° knee bend. See the riding-position diagram to judge the posture for your own body size.
Is the KTM 390 Duke (2024+) LAMS-approved?
Yes — the KTM 390 Duke (2024+) is LAMS-approved, so it is legal for learner and provisional riders in Australia.
Is the KTM 390 Duke too tall for short riders?
It has one of the taller seats in the LAMS naked class at 820 mm, but the bike is extremely narrow, so the effective stretch to the ground is smaller than the spec suggests. Around 170 cm you can expect the balls of both feet down; below that, look at KTM’s lowering options or check your exact reach with your inseam in the simulator.
Is the 390 Duke comfortable for tall riders?
It’s one of the better small bikes for tall riders. The seat-to-peg distance and wide handlebar give a rider up to about 190 cm a reasonably open knee angle and an upright back — the physical size of the bike, not the ergonomics, is what feels small.
Seat height & wheelbase come straight from the manufacturer’s published specs, verified across the maker’s site, media reviews and spec databases.
Handlebar & footpeg positions aren’t published by any manufacturer. Where a true side-profile photo exists, we mark five reference points on it (front & rear axle, seat, grip, peg) and convert pixels to millimetres using the known wheelbase as the scale. Where it doesn’t, we research the grip and peg heights and estimate the horizontal reach from class-typical geometry.
Every result is cross-checked against how reviewers describe the bike’s posture (upright / sporty / committed), and each bike page carries a data-confidence badge so you can see how solid its numbers are.
The drawing is a clean schematic — one shared template per bike type (naked, sport, cruiser, adventure, touring, dirt), anchored to each bike’s real seat, grip and peg coordinates — so you compare riding positions, not paint jobs.
Your figure is a stick model built from your height and inseam using standard body-proportion ratios, then posed by inverse kinematics — hips on the seat, hands on the bars, feet on the pegs — with the same posture solver for every bike.
Bottom line: seat height & wheelbase are hard data; handlebar/footpeg geometry and ground reach are calibrated estimates (see each bike’s data-confidence badge). Always sit on the real bike before you buy.
