Rider Profile

Best ForThis bike suits riders who value simplicity and classic mechanical feel over outright performance, including newer riders comfortable with a kick-start single.
PurposeIt's built as a lightweight, minimalist retro roadster for relaxed street riding rather than speed or distance covering.
Rider FitThe low seat height and light weight make it approachable for shorter or less experienced riders, though the kick-start and drum rear brake demand a bit more manual engagement.
CharacterIt has old-school single-cylinder charm with a thumping, low-revving engine and stripped-down custom styling that rewards a slower, deliberate riding style.
Not Ideal ForThis is not the bike for riders wanting quick acceleration, long highway touring comfort, or any serious off-road capability.

2014 Yamaha SR400 B.s.r 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 2014 Yamaha SR400 B.s.r, 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.
