Rider Profile

Best For	Well suited to newer riders progressing beyond a starter bike as well as experienced riders wanting a light, lively single-cylinder machine.
Purpose	Built primarily as a nimble city and canyon-carving streetfighter rather than a long-distance or off-road machine.
Rider Fit	Its low dry weight and slim trellis chassis make it easy to flick around and manageable for riders of varying strength and stature, though the 830mm seat height may challenge shorter riders.
Character	A punchy, single-cylinder naked bike with sharp handling, strong brakes, and an eager, playful attitude that rewards aggressive riding.
Not Ideal For	Not the right choice for riders seeking a plush, wind-protected long-haul tourer or a capable off-road adventure companion.

Units

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 830mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 2022 KTM 390 Duke, with a relaxed knee angle of around 125 degrees and a forward-leaning riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
