Rider Profile

Best ForThis bike suits new riders or learners building confidence on a small, approachable sportbike before moving to bigger machines.
PurposeIt's designed as an affordable, sporty-looking commuter and learner bike rather than a genuine high-performance machine.
Rider FitIts low seat height and light overall weight make it manageable for shorter or less experienced riders.
CharacterIt has a keen, race-replica look with modern touches like an upside-down fork and digital dash, but performance stays modest and beginner-friendly.
Not Ideal ForIt's not suited to experienced riders seeking real speed, long-distance touring comfort, or any serious off-road capability.

2022 Sinnis GPX 125 Rider Ergonomics Assessment

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

Feet:

At 816mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2022 Sinnis GPX 125, with a cramped knee angle of around 70 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.
