Rider Profile

Best ForA friendly, low-intimidation single that suits newer riders or experienced riders wanting a simple, analog machine.
PurposeBuilt for classic-styled city riding, short jaunts, and enjoying the mechanical simplicity of a kick-start single rather than for outright performance.
Rider FitLight weight and a moderate seat height make it easy for shorter or less physically strong riders to manage at low speed and in traffic.
CharacterA charming, old-school retro roadster that rewards relaxed, unhurried riding with plenty of mechanical character.
Not Ideal ForNot suited for highway touring, two-up long distances, or riders wanting strong acceleration and modern performance.

2016 Yamaha SR400 Rider Ergonomics Assessment

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

Feet:

At 785mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2016 Yamaha SR400, 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.
