Rider Profile

Best ForThis bike suits new and young riders, often learner-legal or restricted-license riders, taking their first steps into sportbike styling and handling.
PurposeIt's built for mimicking full-size supersport looks and sharpening cornering skills at low speed and low risk rather than for outright performance.
Rider FitIts compact, lightweight chassis and low-ish seat height make it easy to manage for smaller or less experienced riders.
CharacterIt has the sharp, aggressive persona of a miniature race replica, eager to be revved hard and flicked through corners.
Not Ideal ForIt is not suited to riders wanting real highway speed, long-distance touring comfort, or two-up passenger practicality.

2018 Aprilia RS 50 Replica 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 Aprilia RS 50 Replica, 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.
