Rider Profile

Best ForThis is a learner-legal 50cc sportbike best suited to beginners, young riders, or those restricted to moped-class machines rather than seasoned veterans seeking outright performance.
PurposeIt's built as a mini sportbike for around-town fun, learning race-style riding technique, and short sporty jaunts rather than serious speed or distance work.
Rider FitIts light dry weight and low seat height make it very manageable for smaller or less experienced riders, though the compact sportbike ergonomics may cramp taller riders on longer rides.
CharacterThe RS2 50 has a nimble, flickable, race-replica personality with sharp steering geometry and sporty componentry that punches above its tiny engine size.
Not Ideal ForThis bike is not for riders wanting real highway speed, long-distance touring comfort, passenger carrying, or any kind of off-road capability.

2010 Rieju RS2 50 Fr 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 50 Fr, 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.
