Rider Profile

Best ForThis bike is best suited to learners and younger riders taking their first steps into sportbike ownership, often under license restrictions limiting engine size.
PurposeIt's built for nimble, playful sport riding on twisty roads and around town rather than outright speed, thanks to its tiny two-stroke engine and sportbike ergonomics.
Rider FitIts very low weight and compact dimensions make it easy to manage for smaller or less experienced riders, though the sporty riding position still leans the rider forward.
CharacterIt has the look and handling feel of a proper sportbike shrunk down, with sharp steering and a lightweight chassis that rewards revving the small two-stroke engine hard.
Not Ideal ForIt's not the right choice for anyone needing real highway speed, long-distance comfort, or the ability to comfortably carry a passenger.

2019 Aprilia RS 50 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 2019 Aprilia RS 50, with a cramped knee angle of around 70 degrees and a forward-leaning riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
