Rider Profile

Best ForThis is a first motorcycle built for young children just starting out in motocross, not for teen or adult riders of any skill level.
PurposeIt exists purely to teach a child the fundamentals of balance, throttle control, and off-road riding in a safe, low-powered package.
Rider FitIts very low 653 mm seat height and lightweight small-bore chassis are sized specifically for small children, with an adjustable centrifugal clutch to tailor power delivery to their skill.
CharacterIt behaves like a purpose-built miniature dirt bike, docile and forgiving with an automatic single-speed gearbox that removes clutch and shifting complexity so a child can focus on riding.
Not Ideal ForIt is not suitable for adults, taller teens, road use, touring, or anyone seeking real speed or highway capability.

2014 KTM 50 SX Rider Ergonomics Assessment

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

Feet:

At 684mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2014 KTM 50 SX, with a cramped knee angle of around 55 degrees and an upright 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.
