Rider Profile

Best ForBest suited to riders with at least some prior experience, since the tall seat height, light weight and supermoto sharpness reward confident, active riding.
PurposeDesigned as a fun, flickable supermoto for tight roads, urban darting and light off-road or track-day antics rather than outright speed or long-distance travel.
Rider FitIts low dry weight and narrow chassis make it easy to muscle around, but the tall 850mm seat height demands reasonable leg length and confidence at a stop.
CharacterA playful, minimalist street-legal supermoto that thrives on sharp handling, quick direction changes and an engaged, hooligan riding style.
Not Ideal ForNot a good fit for riders wanting sustained highway speed, plush comfort, big fuel range, or a relaxed two-up touring experience.

2020 HM Derapage 125 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 2020 HM Derapage 125, 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.
