Rider Profile

Best ForIdeal for beginners and A1 licence holders learning sportbike dynamics; also a fun, cheap toy for experienced riders.
PurposeA pint-sized sport machine for spirited canyon carving, commuting and track-day schooling, teaching real sportbike technique on low power.
Rider FitCommitted sporty stance with clip-ons and rearsets, tall 824mm seat, but featherweight 147kg makes it easy to flick and manage.
CharacterEnergetic, revvy and razor-sharp; a proper baby superbike that rewards momentum and precise lines rather than brute power.
Not Ideal ForNot for riders wanting highway speed, two-up touring, long-distance comfort or any off-road use.

2019 KTM RC 125 Rider Ergonomics Assessment

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

Feet:

At 820mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2019 KTM RC 125, with a cramped knee angle of around 70 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.
