Rider FitIts low seat height and light dry weight make it easy to manage for shorter or less physically strong riders.
CharacterIt offers a nimble, approachable, and unintimidating ride with modest power delivery suited to city streets.
Not Ideal ForThis bike is not for experienced riders seeking high speed, long-distance touring comfort, or off-road capability.

2005 MZ RT 125 Rider Ergonomics Assessment

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

Feet:

At 770mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2005 MZ RT 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.
