Rider Profile

Best ForBest suited to newer or intermediate riders who want a proper sportbike experience without the weight or intimidation of a liter-class machine.
PurposeBuilt primarily for spirited cornering, track days, and sharp urban riding rather than long-distance comfort.
Rider FitIts light weight and low-ish handlebars mean a forward-leaning sporty crouch that favors shorter, fitter riders over long hours in the saddle.
CharacterA nimble, high-revving single-cylinder sport machine that rewards aggressive throttle and brake inputs with eager, flickable handling.
Not Ideal ForNot a good fit for riders seeking plush long-haul comfort, pillion-friendly touring, or any serious off-road capability.

2018 KTM RC 390 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 2018 KTM RC 390, 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.
