Rider Profile

Best ForSuits new-to-intermediate riders who want a light, forgiving supermoto to sharpen their skills without being overwhelmed by power.
PurposeBuilt for tight, twisty urban streets and supermoto-style playfulness rather than outright speed or long-distance travel.
Rider FitIts low 112 kg dry weight and slim chassis make it easy to manage for smaller or less experienced riders, though the 870 mm seat height demands reasonable inseam.
CharacterA nimble, flickable little supermoto with sporty street-legal styling, a racing-inspired exhaust note, and a chassis tuned for quick direction changes.
Not Ideal ForNot a good fit for riders seeking highway speed, long-range touring comfort, or serious off-road capability.

2023 Rieju MRT 125 SM LC Rider Ergonomics Assessment

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

Feet:

At 870mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2023 Rieju MRT 125 SM LC, 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.
