Rider Profile

Best ForThis is a beginner-friendly small-displacement sport bike, well suited to new riders building confidence.
PurposeIt's aimed at low-cost commuting and casual sporty riding around town rather than serious performance.
Rider FitIts light dry weight and modest seat height make it easy to manage for smaller or less experienced riders.
CharacterThe bike has a lightweight, single-cylinder sporty feel with basic but functional running gear.
Not Ideal ForIt's not a good choice for highway touring, high-speed riding, or off-road use given its small engine and street-oriented setup.

2010 UM Fastwind 125 Rider Ergonomics Assessment

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

Feet:

At 760mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 UM Fastwind 125, with a cramped knee angle of around 65 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.
