Rider Profile

Best ForThis bike suits beginner to intermediate riders who want a relaxed, low-stress cruiser experience.
PurposeIt's built for easy-going cruising and casual around-town riding rather than outright performance.
Rider FitThe low 700mm seat height and mild power delivery make it approachable for shorter or less physically strong riders.
CharacterIt has a classic laid-back cruiser character with a torquey V-twin feel and modest, unintimidating performance.
Not Ideal ForIt's not suited to riders seeking sharp handling, high-speed touring, or any off-road capability.

2008 Suzuki Boulevard 400 Rider Ergonomics Assessment

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

Feet:

At 700mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2008 Suzuki Boulevard 400, 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). 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.
