Rider Profile

Best ForThis is a 50cc sport-styled minibike best suited to beginners, learners, and younger riders taking their first steps on two wheels.
PurposeDesigned as a compact naked sportbike, it excels at short, playful rides around town and light track-day style practice rather than serious performance riding.
Rider FitIts low seat height and light dry weight make it very approachable for shorter or lighter riders, with minimal physical demand to handle.
CharacterIts inverted fork, mono-shock, double front discs, and sporty proportions give it a surprisingly premium, aggressive look and sharp handling feel for its tiny displacement.
Not Ideal ForIt is not suitable for highway travel, long-distance touring, carrying a passenger, or riders seeking real straight-line speed or power.

2019 Rieju RS3 NKD 50 Rider Ergonomics Assessment

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

Feet:

At 845mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2019 Rieju RS3 NKD 50, with a cramped knee angle of around 75 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.
