Rider Profile

Best For	Ideal for beginners and A1 licence holders; a forgiving, learner-friendly sportbike that also rewards experienced riders honing technique.
Purpose	A pint-sized track-styled sportbike built for spirited backroad riding, carving corners, commuting, and learning proper sport riding skills.
Rider Fit	Light 144kg with a committed sport riding position: clip-on bars, 820mm seat and rear-set pegs. Compact and manageable but leaning-forward and firm.
Character	A miniature superbike with real GP-inspired attitude - eager, revvy single that must be worked hard, delivering big-bike thrills at modest speeds.
Not Ideal For	Not for those wanting outright speed, relaxed touring comfort, two-up practicality, off-road use, or a laid-back upright commuter.

Inseam (optional)

Units

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

Feet:

At 805mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Aprilia RS 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.
