Rider Profile

Best ForThis is a beginner-friendly machine, well suited to new riders or those wanting a low-stress, low-power commuter.
PurposeIt's designed as a small-capacity cruiser-style allrounder for easy urban riding rather than performance or adventure use.
Rider FitThe low seat height and light dry weight make it very manageable for shorter or less physically strong riders.
CharacterIt has a relaxed, unhurried personality with modest torque and a simple, forgiving chassis setup.
Not Ideal ForIt's not suited to riders seeking highway touring speed, off-road capability, or spirited cornering performance.

2005 Hyosung RT 125 Karion Rider Ergonomics Assessment

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

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2005 Hyosung RT 125 Karion, with a relaxed knee angle of around 120 degrees and a forward-leaning 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.
