Rider Profile

Best For	This bike suits newer or younger riders, often on a restricted licence, who want sportbike looks and handling without overwhelming power.
Purpose	It's built for sporty around-town riding and mimicking full-size supersport style and cornering feel in a lightweight, learner-legal package.
Rider Fit	Its low seat height, light dry weight, and compact dimensions make it very manageable for shorter or lighter riders.
Character	It has an aggressive sportbike stance with premium touches like an upside-down fork and radial front caliper, giving it a punchy, eager feel despite modest power.
Not Ideal For	It's not a good fit for riders wanting real highway speed, long-distance touring comfort, or any 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 2009 Derbi GPR 125 4T 4V, 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.
