Rider Profile

Best ForThis bike suits beginners and learner riders who want a light, unintimidating machine to build confidence on.
PurposeIt's designed as an entry-level enduro-styled commuter, more suited to light trails and urban streets than serious off-road work or highway travel.
Rider FitIts low power output and modest 142 kg dry weight make it easy to manage for smaller or less experienced riders, though the 825 mm seat height requires reasonable inseam length.
CharacterIt has a friendly, forgiving nature with gentle power delivery from its small single-cylinder engine, prioritizing approachability over performance.
Not Ideal ForThis is not the bike for experienced riders seeking real off-road capability, sustained highway speeds, or long-distance touring comfort.

2021 Keeway TX 125 E4 Rider Ergonomics Assessment

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

Feet:

At 825mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2021 Keeway TX 125 E4, with a cramped knee angle of around 70 degrees and an upright 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.
