Rider Profile

Best For	Best suited to riders who already have experience handling heavy, low-slung cruisers due to the substantial 344 kg curb weight.
Purpose	Built for relaxed boulevard cruising and highway touring rather than sport riding or commuting agility.
Rider Fit	The low 720 mm seat height helps shorter riders reach the ground, but the bike's mass demands decent upper-body and core strength at low speeds and when maneuvering.
Character	A big-displacement V-twin cruiser with deep torque, shaft drive smoothness, and a classic laid-back custom aesthetic.
Not Ideal For	Not a good fit for riders seeking sharp cornering, off-road capability, or a lightweight, flickable ride.

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

Feet:

At 720mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2021 Suzuki Boulevard C90 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.
