Rider Fit	The low seat height and light dry weight make it very manageable for shorter or less physically strong riders.
Character	It has a mild-mannered, approachable character with modest power delivery and simple, forgiving handling.
Not Ideal For	It's not suited for highway touring, two-up long distance travel, or riders seeking strong acceleration and high-speed stability.

Units

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 2009 Hyosung RT 125D, with a moderate knee angle of around 115 degrees and a forward-leaning 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.
