Rider Profile

Best ForThis small-capacity supermoto suits beginners and learner-licence riders looking for an approachable, low-powered first bike.
PurposeIt's built primarily for nimble urban commuting and light around-town fun rather than outright performance.
Rider FitThe low seat height and light dry weight make it easy to handle for shorter or less experienced riders.
CharacterIt has a playful, flickable supermoto character with modest single-cylinder power delivery.
Not Ideal ForIt's not suited to highway touring, carrying a passenger long distances, or riders wanting strong outright speed.

2011 Hyosung RX125D SM Rider Ergonomics Assessment

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

Feet:

At 840mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2011 Hyosung RX125D SM, with a relaxed knee angle of around 130 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.
