Rider Profile

Best ForBest suited to younger or novice riders and minibike enthusiasts, though its light weight and sharp handling can amuse experienced riders on tight tracks too.
PurposeBuilt as a small-displacement supermoto for playful, tight-corner fun on minibike tracks and light urban scooting rather than serious speed or distance work.
Rider FitIts very low dry weight and accessible seat height make it easy to handle and flick around for riders of most sizes and skill levels.
CharacterA nimble, high-revving two-stroke minimoto with sharp steering geometry that rewards aggressive, playful riding in tight spaces.
Not Ideal ForNot suitable for highway travel, long-distance touring, passengers, or riders expecting strong outright power or high top speed.

2021 Sherco Silver SM-R 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 Silver SM-R, 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.
