Rider Profile

Best For	Suited to new or returning riders and scooter commuters comfortable with automatic transmissions rather than experienced motorcyclists.
Purpose	Designed as a sporty, performance-styled automatic scooter for zipping through urban traffic rather than serious speed or long-distance travel.
Rider Fit	Its low seat height and light dry weight make it easy to manage for smaller or less physically strong riders.
Character	A cheeky, sport-styled maxi-scooter that mimics superbike looks with upside-down forks and twin discs while staying practical and automatic underneath.
Not Ideal For	Not for riders seeking real high-speed performance, long highway 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 GP1 125 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.
