Rider Profile

Best ForBest suited to new and young riders, often as a first bike or learner-legal machine, though its sporty nature rewards a confident throttle hand.
PurposeDesigned for sharp, playful sport riding around town and twisty backroads rather than outright speed, thanks to its 50cc two-stroke racing pedigree.
Rider FitIts compact, lightweight sportbike chassis and low seat height make it accessible to smaller or less experienced riders.
CharacterA miniature race replica that mimics full-size sportbike ergonomics and handling in a small, high-revving two-stroke package.
Not Ideal ForNot for riders seeking real-world touring range, highway speed, or two-up comfort.

2008 Derbi GPR 50 Racing Rider Ergonomics Assessment

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

Feet:

At 845mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2008 Derbi GPR 50 Racing, with a cramped knee angle of around 75 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.
