Rider Profile

Best ForSuited to new and younger riders, typically those with a moped or scooter licence rather than seasoned motorcyclists.
PurposeBuilt for quick, nimble urban commuting and short hops around town rather than any kind of serious distance riding.
Rider FitIts very light dry weight and low seat height make it extremely easy to handle and manageable for smaller or less physically strong riders.
CharacterA sporty, GP-styled 50cc scooter that feels lively and fun in city traffic thanks to its light weight and sharp handling, even though its two-stroke engine keeps outright speed modest.
Not Ideal ForNot suitable for riders wanting highway speeds, long-distance touring comfort, or a passenger-friendly two-up machine.

Rider Fit Visualizer

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

Feet:

At 770mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2007 Aprilia Sonic 50 GP, with a moderate knee angle of around 95 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.
