Rider Profile

Best ForThis lightweight air-cooled 125cc sportbike suits newer riders or those wanting a nimble, low-stakes machine to sharpen cornering skills.
PurposeBuilt as a small-displacement sport machine, it's aimed at learner-legal thrills and playful backroad riding rather than outright speed.
Rider FitIts low dry weight and modest 800mm seat height make it approachable for shorter or less physically strong riders.
CharacterIt has the feel of a scaled-down superbike, with sporty ergonomics, a firm suspension setup, and eager handling in tight corners.
Not Ideal ForIt is not suited to highway touring, carrying a passenger comfortably, or riders seeking strong outright power.

2010 Rieju RS2 Pro 125 Rider Ergonomics Assessment

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

Feet:

At 800mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 Rieju RS2 Pro 125, with a cramped knee angle of around 70 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.
