Rider Profile

Best ForBest suited to experienced riders who are comfortable managing a heavy, high-torque cruiser with a massive rear tire.
PurposeBuilt for boulevard cruising and strong straight-line acceleration rather than nimble cornering or long-distance touring.
Rider FitThe low 705mm seat height is approachable, but the nearly 350kg weight demands confident strength and balance at low speeds and when maneuvering.
CharacterA muscular, torque-heavy power cruiser with a big V-twin rumble, aggressive styling, and a wide 240-section rear tire that defines its identity.
Not Ideal ForNot for riders seeking light, flickable handling, off-road capability, or a nimble city commuter.

2012 Suzuki Boulevard M109R 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 2012 Suzuki Boulevard M109R, 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.
