Rider Profile

Best ForBest suited to younger or novice riders, or experienced riders looking for a fun, low-stakes minimoto-style machine, since this is a tiny 50cc two-stroke supermoto with a kickstart and no listed power figure.
PurposeBuilt for playful, sharp-handling supermoto antics on tight tarmac circuits, car parks, and mini-track days rather than any kind of serious speed or distance riding.
Rider FitIts very low dry weight of 83 kg and 850 mm seat height make it easy to flick around and manage for smaller or lighter riders, including teens transitioning up from smaller bikes.
CharacterA light, nimble, high-revving two-stroke supermoto with premium-feel components like an upside-down fork and adjustable monoshock, designed purely for grin-inducing agility over outright pace.
Not Ideal ForNot a fit for riders wanting real highway speed, long-distance touring comfort, passenger carrying, or genuine off-road capability.

2021 Sherco 50 SM-RS 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 2021 Sherco 50 SM-RS, with a relaxed knee angle of around 125 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.
