Best ForBest suited to experienced riders comfortable managing a heavy, powerful, long, low-slung cruiser at low speeds and in traffic.
PurposeBuilt for boulevard cruising and straight-line power thrills rather than nimble cornering or commuting efficiency.
Rider FitIts low seat height suits shorter riders but the substantial 347 kg mass demands solid strength and confidence when maneuvering at a stop or parking.
CharacterA muscular, torque-heavy V-twin cruiser with a massive rear tire and blacked-out custom styling that rewards relaxed, throttle-happy riding.
Not Ideal ForNot a good fit for riders seeking a lightweight, flickable bike for tight city streets or technical backroads.

2020 Suzuki Boulevard M109R B O S S Rider Ergonomics Assessment

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

Feet:

At 705mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 Suzuki Boulevard M109R B O S S, with a cramped knee angle of around 80 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.
