Rider Profile

Best ForSuited to new and learner riders, including younger riders on a 50cc licence, thanks to its simple automatic transmission and light controls.
PurposeBuilt as a nimble, sporty-styled urban scooter for short commutes and city errands rather than any serious performance riding.
Rider FitIts low seat height and light dry weight make it easy to handle for riders of smaller stature or those wanting a low-effort ride.
CharacterA peppy, sport-styled 50cc scooter that feels lively around town thanks to its two-stroke engine and aggressive Aprilia styling.
Not Ideal ForNot suitable for riders wanting highway speeds, long-distance touring comfort, or any off-road capability.

Rider Fit Visualizer

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

Feet:

At 820mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 2016 Aprilia SR 50 R, with a moderate knee angle of around 105 degrees and a slightly forward 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.
