Rider Profile

Best ForThis scooter suits new or novice riders, including younger license holders limited to 50cc machines, thanks to its simple automatic transmission and light controls.
PurposeIt's built for short urban hops, commuting, and running errands around town rather than any kind of serious performance riding.
Rider FitIts low seat height, light weight, and automatic clutch make it very easy to manage physically, even for smaller or less experienced riders.
CharacterIt has a sporty, aggressive styling identity with racing-inspired brakes and bodywork that give it a performance-scooter attitude despite its modest 50cc output.
Not Ideal ForIt is not suitable for highway travel, long-distance touring, or riders seeking real straight-line speed or passenger comfort.

2015 Aprilia SR 50 R Factory 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 2015 Aprilia SR 50 R Factory, 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.
