Rider Profile

Best ForSuitable for beginners and learners, including younger riders on a moped license, thanks to its 50cc automatic twist-and-go nature.
PurposeBuilt as a sporty, style-focused urban commuter scooter rather than a machine for long distances or high speed.
Rider FitIts low seat height and light weight make it easy and unintimidating for smaller or less experienced riders to manage.
CharacterA sharp-looking, sport-styled 50cc scooter with premium touches like an inverted fork and radial brake caliper that give it a surprisingly grown-up feel for its class.
Not Ideal ForNot for riders wanting real highway speed, long-distance touring comfort, or any off-road capability.

2011 Derbi GP1 50 Rider Ergonomics Assessment

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

Feet:

At 835mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2011 Derbi GP1 50, with a moderate knee angle of around 105 degrees and a slightly forward 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.
