The KTM RC 390 (2024+) has a 824 mm (32.4 in) seat height and a 1343 mm wheelbase. For an average 175 cm rider that works out to about 16° of forward lean with the knees bent to about 92°, and that rider can get just the toes down (tip-toe). See the riding-position diagram above, and enter your own height and inseam to see your fit. The KTM RC 390 (2024+) is LAMS-approved (learner-legal to ride in Australia).
The KTM RC 390 (2024+) in the real world
The RC 390 is the most hardcore riding position in the LAMS class. This is a genuine race-bred supersport in miniature: the clip-ons mount below the top triple clamp, dropping your torso well forward, and the pegs are set high and rearset for cornering clearance. Where most learner sport bikes soften the stance to be friendly, KTM deliberately didn’t — it’s the closest a LAMS rider gets to a full supersport crouch.
The 824 mm seat is tall for a small-capacity bike, and combined with the aggressive forward lean it makes the RC 390 the least casual of the learner faired bikes at a standstill. The short 1343 mm wheelbase — the shortest in this group — reinforces the compact, racy feel. Riders after a track-day toy and a committed position love it; anyone chasing a comfortable commuter should know going in that this one asks something of your wrists and lower back.
Who the RC 390 fits
The most aggressive LAMS sport position — clip-ons below the triple clamp and high rearset pegs make a real forward crouch, not a token lean.
Best for riders who actively want a supersport feel; the wrist and lower-back load isn’t for everyone on a daily commute.
The tall 824 mm seat on a compact bike means shorter riders can reach the ground but sit in a committed stretch to the bars.
Taller riders get a racy fit with knees tucked high; the short wheelbase makes the whole bike feel small.
Common fit & comfort changes
Tank grip pads — Close to essential on this leant-forward bike; strong knee grip on the tank is what takes weight off your wrists.
Comfort seat — The stock seat is thin and racy; a reshaped seat is the first thing many owners add for anything past a short ride.
Clip-on risers — Room to move is limited by the aggressive setup, but a small lift noticeably eases wrist load for riders using it on the road.
Most of these can be previewed on your own body with the “Adjust the fit” sliders in the simulator above.
The KTM RC 390 (2024+) has a seat height of 824 mm (32.4 inches).
Can a 175 cm rider flat-foot the KTM RC 390 (2024+)?
On its 824 mm seat, a 175 cm rider (about 80 cm inseam) can typically get just the toes down (tip-toe) on the KTM RC 390 (2024+). Taller or shorter riders differ — use the simulator to check your own ground reach.
What is the riding position of the KTM RC 390 (2024+)?
For an average 175 cm rider, the KTM RC 390 (2024+) riding position (also called the seating position) works out to about 16° of forward lean with a 92° knee bend. See the riding-position diagram to judge the posture for your own body size.
Is the KTM RC 390 (2024+) LAMS-approved?
Yes — the KTM RC 390 (2024+) is LAMS-approved, so it is legal for learner and provisional riders in Australia.
Does the KTM RC 390 have an aggressive riding position?
Yes — the most aggressive in the LAMS class. The clip-ons sit below the top triple clamp for a real forward crouch and the pegs are high and rearset. It’s a race-styled supersport in miniature, not a softened learner bike.
Is the RC 390 comfortable to commute on?
Less so than most LAMS sport bikes. The committed forward lean puts steady weight on your wrists and lower back in traffic. Riders who daily one grip the tank hard and often add a comfort seat; if you want an easy commute, a more upright LAMS bike will suit better.
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.
