Rider Profile

Best ForSuitable for beginners and learner-permit riders thanks to its automatic transmission and modest 125cc output.
PurposeDesigned as a practical commuter scooter for urban and suburban riding rather than performance or adventure use.
Rider FitThe 770mm seat height and 199kg weight make it manageable for most adult riders, though the heft is noticeable at low speeds and when maneuvering.
CharacterA comfortable, easygoing maxi-scooter that prioritizes stability and everyday usability over excitement.
Not Ideal ForNot for riders seeking highway-speed touring capability, off-road use, or spirited cornering performance.

2005 Aprilia Atlantic 125 Rider Ergonomics Assessment

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

Feet:

At 678mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2005 Aprilia Atlantic 125, with a cramped knee angle of around 75 degrees and an upright 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.
