Rider Profile

Best ForBest suited to younger or novice riders, often as a stepping stone before moving to larger supermotard or sportbike machines.
PurposeBuilt for playful, flickable fun on tight city streets and supermoto-style circuits rather than outright speed or distance.
Rider FitIts tiny 99 kg mass and low-effort controls make it accessible to smaller or lighter riders, though the tall 860 mm seat height demands reasonable leg length.
CharacterA high-revving two-stroke minimoto with sharp, go-kart-like handling and an eager, buzzy character that rewards aggressive cornering lines.
Not Ideal ForNot for riders wanting real highway speed, long-distance comfort, or a passenger-friendly machine.

2019 Aprilia SX 50 Factory Rider Ergonomics Assessment

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

Feet:

At 875mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2019 Aprilia SX 50 Factory, with a relaxed knee angle of around 135 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.
