Rider Profile

Best ForThis is a learner-legal 50cc sportbike aimed at new riders, typically teenagers on a moped licence, rather than experienced motorcyclists.
PurposeIts purpose is short urban and suburban commuting with sporty styling, not genuine performance riding.
Rider FitThe compact, lightweight sportbike chassis suits smaller and lighter riders, with a low-ish seat height and racy but not extreme ergonomics.
CharacterIt looks and feels like a mini superbike, offering playful handling and a sporty riding position despite very modest two-stroke performance.
Not Ideal ForThis is not for riders wanting real speed, highway travel, passenger comfort, or off-road capability.

Character map is an editorial estimate based on this bike's specifications, not a lab-tested measurement.

2012 Derbi GPR 50 2T Rider Ergonomics Assessment

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

Feet:

At 810mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 Derbi GPR 50 2T, with a cramped knee angle of around 70 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.
