Rider Profile

Best ForNote: the given specifications are for the Yamaha FZ-X, a scrambler-styled sibling of the FZ-S, so this profile reflects that model rather than the FZ-S Fi directly; it suits beginners and casual riders comfortable on a light, low-powered commuter.
PurposeBuilt primarily as an around-town commuter with light scrambler styling rather than a performance or adventure machine.
Rider FitIts low seat height and light 139 kg weight make it very manageable for riders of most sizes and shorter inseams.
CharacterA friendly, easygoing single-cylinder runabout that favors smooth, relaxed torque delivery over outright speed or aggression.
Not Ideal ForNot suited for highway touring, high-speed travel, serious off-road use, or riders seeking strong passenger comfort over distance.

2020 Yamaha FZ-S Fi Rider Ergonomics Assessment

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

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 Yamaha FZ-S Fi, with a moderate knee angle of around 115 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.
