Rider Profile

Best ForThis tiny supermoto-style minibike suits newer or younger riders, or experienced riders looking for a fun, low-stakes toy.
PurposeIt's built for playful, short-distance urban riding and messing around rather than serious transportation or performance riding.
Rider FitIts very low seat height and featherweight 68.5 kg build make it extremely easy and unintimidating to handle for almost any rider size.
CharacterIt has a cheeky, go-kart-like personality with mini 10-inch wheels and supermotard styling that rewards flickable, playful riding.
Not Ideal ForIt is not suitable for highway travel, long-distance touring, or riders needing serious power and stability at speed.

2009 Polini XP 4 Street 125 Rider Ergonomics Assessment

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

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 Polini XP 4 Street 125, with a moderate knee angle of around 110 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.
