Rider Profile

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

At 810mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2011 KTM 125 Duke, with a relaxed knee angle of around 120 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.
