Rider Profile

Best ForBest suited to younger or less experienced riders, often as a stepping stone bike or for licensed minibike/supermoto competition, given its tiny 50cc two-stroke displacement.
PurposeBuilt as a pint-sized supermoto for sharp, flickable fun on tight tracks and urban streets rather than any serious speed or distance work.
Rider FitExtremely light dry weight and a tall-ish but narrow seat make it easy to muscle around, though the 850mm seat height and minimal size favor smaller or shorter riders.
CharacterA playful, high-revving two-stroke supermoto with premium-feeling components like an inverted Marzocchi fork and radial brakes packed into a tiny, toy-like chassis.
Not Ideal ForNot suitable for riders wanting highway speed, long-distance comfort, passenger carrying, or genuine off-road capability.

2013 Rieju MRT Pro 50 SM Rider Ergonomics Assessment

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

Feet:

At 850mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2013 Rieju MRT Pro 50 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.
