Rider Profile

Best ForThis is best suited to new or young riders, often as a learner-legal 50cc sportbike, though its full-size sportbike chassis will also appeal to experienced riders wanting a lightweight track toy.
PurposeBuilt as a miniature race replica, it's designed for sharp cornering, sporty styling, and fun at low speeds rather than outright velocity.
Rider FitIts compact, low-slung sportbike ergonomics with a fairly low seat height suit smaller and shorter riders comfortably, though the aggressive riding position can tire larger riders on longer rides.
CharacterA feisty, high-revving little sportbike that mimics the look and handling feel of its bigger GP-inspired siblings, rewarding an energetic, playful riding style.
Not Ideal ForThis is not the right choice for riders wanting real highway speed, long-distance touring comfort, or genuine two-up capability.

2007 Derbi GPR Racing 50 Rider Ergonomics Assessment

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 2007 Derbi GPR Racing 50, 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.
