Rider Profile

Best ForThis is an ideal machine for beginners or new riders building confidence, thanks to its low seat height, light weight, and gentle power delivery.
PurposeDesigned as a relaxed commuter and casual cruiser-styled runabout rather than a performance machine, it suits easy urban riding and short leisurely trips.
Rider FitThe ultra-low slung seat, light 129 kg weight, and low center of gravity make it very approachable for shorter or less physically strong riders.
CharacterIt has laid-back cruiser styling with a teardrop tank and raised handlebars, favoring relaxed, upright, low-stress riding over sportiness.
Not Ideal ForIt is not suited for riders wanting highway speed, long-distance touring comfort, off-road capability, or carrying a passenger over long trips.

2008 Yamaha YBR125 Custom Rider Ergonomics Assessment

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

Feet:

At 760mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2008 Yamaha YBR125 Custom, with a cramped knee angle of around 80 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.
