Rider Profile

Best ForBest suited to younger or newer riders cutting their teeth on a lightweight, high-revving supermoto before moving to bigger machines.
PurposeBuilt for flickable, playful riding around town and tight, twisty roads rather than outright speed or distance.
Rider FitIts low 97 kg dry weight and slim proportions make it very easy to muscle around, though the 855 mm seat height and firm suspension suit shorter to average riders best.
CharacterA sharp, buzzy two-stroke supermoto that rewards revving hard and throwing it into corners with confidence.
Not Ideal ForNot for riders wanting sustained highway speeds, long-distance comfort, or a passenger-friendly ride.

2012 Derbi Senda X-Race 50 SM Rider Ergonomics Assessment

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

Feet:

At 855mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2012 Derbi Senda X-Race 50 SM, 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.
