Rider Profile

Best For	Well suited to new and early-intermediate riders thanks to its light single-cylinder power delivery and manageable performance.
Purpose	Built primarily as a nimble city and commuter bike that also enjoys a spirited weekend ride through twisty roads.
Rider Fit	The low 800mm seat height and slim steel trellis chassis make it accessible to shorter riders and easy to manage at a standstill.
Character	A sharp, flickable naked bike with sporty WP suspension that rewards eager, playful riding over long-distance cruising.
Not Ideal For	Not ideal for riders seeking sustained highway touring, heavy off-road use, or two-up comfort over long distances.

Feet:

At 820mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 2021 KTM 250 Duke, with a cramped knee angle of around 70 degrees and a forward-leaning riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
