Rider Profile

Best ForThis is an ideal machine for beginners, learner riders, and those new to motorcycling thanks to its light weight and gentle power delivery.
PurposeIt's built as a lightweight commuter and learner sportbike suited to city streets and light urban riding rather than outright performance.
Rider FitIts low seat height and slim, sub-140kg mass make it extremely manageable for shorter or less physically strong riders.
CharacterThe CBR125R has a nimble, approachable, and forgiving character with sporty styling but modest real-world urgency.
Not Ideal ForIt's not for experienced riders seeking highway performance, long-distance touring comfort, or two-up passenger capability.

2018 Honda CBR125R Rider Ergonomics Assessment

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

Feet:

At 795mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2018 Honda CBR125R, 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.
