Rider Profile

Best ForThis is a maxi-scooter suited to riders of any experience level, including those upgrading from smaller scooters or learners on the appropriate license.
PurposeBuilt as a sporty, automatic maxi-scooter for quick urban transport and spirited commuting rather than outright performance riding.
Rider FitIts low 800mm seat height and light dry weight around 139kg make it accessible and easy to manage for shorter or less physically strong riders.
CharacterBlends scooter convenience with sporty styling, upside-down forks, and disc brakes, giving it a lively, engaged feel around town.
Not Ideal ForNot suited for highway touring, passenger comfort over long distances, or any off-road use given its street-oriented tyres and limited suspension travel.

2009 Derbi GP1 250 Racing 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 2009 Derbi GP1 250 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.
