Rider Profile

Best For	Well suited to beginner and intermediate riders thanks to its light weight, low seat height, and mild single-cylinder power delivery.
Purpose	Built as an entry-level cruiser for relaxed street riding and around-town cruising rather than performance or long-distance touring.
Rider Fit	Very approachable for shorter or lighter riders due to the low 700mm seat height and manageable 173kg curb weight.
Character	A laid-back, classic-styled single-cylinder cruiser that emphasizes simplicity, easy handling, and low-speed charm over outright performance.
Not Ideal For	Not a good fit for riders wanting high speed, aggressive cornering ability, serious off-road capability, or comfortable two-up long-distance touring.

Feet:

At 700mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2021 Suzuki Boulevard S40, with a cramped knee angle of around 75 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).
