Rider Profile

Best ForIdeal for beginners, new licence holders, or riders wanting a light, unintimidating machine to build confidence on.
PurposeBuilt primarily as a nimble commuter and learner-friendly naked for city streets and short hops rather than outright performance.
Rider FitVery low weight and low seat height make it easy to handle for shorter or less physically strong riders.
CharacterA sharp-looking, minimalist naked bike that rewards playful, low-speed riding with quick, flickable handling.
Not Ideal ForNot suited to riders wanting sustained high-speed motorway travel, long-distance touring, or heavy passenger and luggage use.

2021 Honda CB125R 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 2021 Honda CB125R, with a relaxed knee angle of around 120 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.
