Rider Profile

Best ForThis is best suited to younger or licence-restricted riders and supermoto enthusiasts who want a nimble, playful minibike rather than a first-time absolute novice on public roads.
PurposeBuilt as a tiny supermoto for sharp, flickable handling on tight tarmac and go-kart-style track days rather than for outright speed or distance.
Rider FitIts very low dry weight and compact dimensions make it extremely easy to manage and toss around, though the tall-ish 870mm seat height suits shorter, lighter riders best.
CharacterA fun, high-revving two-stroke minimoto with racy supermoto styling, premium-feeling components like an inverted fork and wave discs, and an eager, playful personality.
Not Ideal ForThis is not the right bike for highway travel, carrying a passenger comfortably, long-distance touring, or riders seeking real off-road or high-speed capability.

2019 Rieju MRT 50 SM Pro 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 2019 Rieju MRT 50 SM Pro, 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.
