Rider Profile

Best ForSuited to new and casual riders, including those on a moped or restricted license, thanks to its small 50cc engine and light, manageable chassis.
PurposeBuilt as a sporty urban commuter scooter, designed for weaving through city traffic and short hops rather than long-distance travel.
Rider FitLow seat height and light dry weight make it easy to handle for riders of most sizes, including smaller or less experienced riders.
CharacterA youthful, sporty-styled scooter with premium touches like an upside-down front fork, giving it a more aggressive feel than typical commuter scooters.
Not Ideal ForNot suitable for riders wanting sustained highway speeds, long touring distances, or off-road capability.

2008 Derbi GP1 50 Open Rider Ergonomics Assessment

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

Feet:

At 810mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2008 Derbi GP1 50 Open, 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.
