Rider Profile

Best ForSuitable for absolute beginners or younger riders, requiring no real prior riding skill given its restricted top speed and automatic transmission.
PurposeDesigned purely for short, low-speed urban errands and light commuting rather than any performance or distance riding.
Rider FitVery low seat height and light weight make it easy to manage for smaller or less physically strong riders.
CharacterA playful, small-displacement runabout scooter with a rally-styled look but strictly limited real-world performance.
Not Ideal ForNot suitable for highway use, touring, carrying a passenger comfortably, or anyone wanting spirited or long-distance riding.

2006 Hyosung SF 50 Rally 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 Rally, 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.
