Rider Profile

Best ForThis is an entry-level moped-class scooter suited to complete beginners, learners, or those needing a basic license-friendly runabout.
PurposeBuilt purely for short, low-speed trips around town such as commuting a few kilometers, running errands, or learning basic road skills.
Rider FitIts light dry weight and low 740mm seat height make it extremely easy and unintimidating to handle for riders of nearly any size or strength.
CharacterA humble, economical little machine with a sporty scooter-style fairing, offering peppy step-through practicality rather than any real performance.
Not Ideal ForThis is not for highway travel, touring, carrying a passenger comfortably, or anyone seeking genuine speed or excitement.

2006 Hyosung SF 50 Racing Rider Ergonomics Assessment

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

Feet:

At 740mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2006 Hyosung SF 50 Racing, with a moderate knee angle of around 95 degrees and a slightly forward riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
