Rider Profile

Best ForThis tiny supermotard suits beginners and learner-permit riders who want a light, non-intimidating first bike.
PurposeIt's built for playful urban commuting and darting through city traffic rather than any serious speed or distance work.
Rider FitIts very low weight and manageable 840 mm seat height make it easy for shorter or lighter riders to handle confidently.
CharacterThe Sting 125 has a nimble, flickable, go-kart-like personality that rewards quick direction changes over raw power.
Not Ideal ForIt is not suited to highway touring, carrying a passenger long distances, or riders seeking strong acceleration and top speed.

1999 KTM Sting 125 Rider Ergonomics Assessment

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

Feet:

At 840mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 1999 KTM Sting 125, with a relaxed knee angle of around 130 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.
