Rider Profile

Best ForIdeal first bike for beginners and A1 licence holders; approachable, forgiving power delivery with premium components that reward learning.
PurposeA nimble entry-level naked built for city commuting, learning throttle and cornering skills, and fun back-road blasts.
Rider FitLight and slim with an 800mm seat and upright, roomy naked ergonomics; WP APEX 43 forks and 150mm travel give a controlled, planted ride.
CharacterA sharp, playful single-cylinder streetfighter that punches above its 15 PS with aggressive KTM styling and eager, flickable handling.
Not Ideal ForNot for riders wanting highway speed, two-up touring, or off-road duty; the modest 125cc output limits sustained fast cruising.

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

Feet:

At 830mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2019 KTM 125 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.
