Rider Profile

Best For	This bike suits new and younger riders, including those on a learner or A1-equivalent licence, who want a light, approachable machine to build confidence on.
Purpose	It's built as a nimble supermoto-styled commuter for weaving through city traffic and having fun on twisty back roads rather than for outright speed.
Rider Fit	Its low weight and tall but slim seat make it easy to manage at a stop for shorter or less experienced riders, though the 880mm seat height requires reasonable inseam length.
Character	Playful, flickable, and eager to be thrown around corners, it rewards an energetic riding style over long-distance cruising.
Not Ideal For	It's not the right choice for riders wanting highway speed, long motorway touring comfort, or serious off-road capability.

Units

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

Feet:

At 830mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 2017 Aprilia SX 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.
