Rider Profile

Best ForThis is a small-displacement moped-class scooter best suited to absolute beginners, learners, or those restricted to 50cc licenses.
PurposeIt's designed for very short, low-speed urban errands rather than any kind of performance or long-distance riding.
Rider FitIts light weight and low seat height make it easy and unintimidating for smaller or less experienced riders to handle.
CharacterIt has a modest, unassuming personality focused on simple, economical, easygoing transportation rather than excitement.
Not Ideal ForIt is not suitable for highway riding, touring, carrying a passenger comfortably, or anyone seeking speed or performance.

2012 Kymco RS 50 Rider Ergonomics Assessment

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

Feet:

At 780mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 Kymco RS 50, with a moderate knee angle of around 100 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.
