Rider Profile

Best ForBest suited to younger or novice riders, often on a learner license, who are building skill in a lightweight, low-powered supermoto package.
PurposeDesigned for playful, nimble city riding and light supermoto-style fun rather than any serious speed or distance work.
Rider FitIts tall 870mm seat height and 85kg dry weight favor a rider comfortable balancing a tall, flickable bike but who doesn't need much muscle to manage it at a stop.
CharacterA tiny, high-revving two-stroke supermoto that rewards eager throttle use and sharp cornering lines over outright pace.
Not Ideal ForNot a fit for riders wanting highway speed, long-distance touring capability, or a passenger-friendly setup.

Feet:

At 870mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2022 Rieju MRT 50 SM, with a relaxed knee angle of around 135 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.
