Rider Profile

Best For	Well suited to new and young riders who want a sporty feel while learning, though the sharp handling rewards a bit of prior riding experience too.
Purpose	Built for zipping through twisty roads and city streets with sportbike styling and a playful, lightweight chassis rather than for outright speed.
Rider Fit	Its light dry weight and compact, low-slung sportbike ergonomics make it easy to manage for shorter or lighter riders, though the low bars mean a forward-leaning stance.
Character	A pint-sized sport bike with race-inspired running gear, a peppy two-stroke engine, and go-kart-like agility that punches above its small displacement.
Not Ideal For	Not the right choice for riders wanting sustained highway speeds, long-distance touring comfort, or off-road capability.

Units

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

Feet:

At 800mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2005 Derbi GPR 125 Racing, 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.
