Rider Profile

Best For	Best suited to riders with at least some experience handling a heavy, low-slung cruiser, thanks to its 328 kg mass and long wheelbase.
Purpose	Built for relaxed boulevard cruising and stoplight-to-stoplight torque-driven acceleration rather than outright speed or cornering agility.
Rider Fit	The low 716 mm seat height makes it approachable for shorter riders, but the substantial weight demands confident low-speed balance and upper body strength at a stop.
Character	A big-twin power cruiser with strong low-end torque, a shaft drive for low maintenance, and classic chromed styling that favors presence and comfort over sharp handling.
Not Ideal For	Not a good fit for riders wanting a lightweight, flickable bike for tight canyon roads or any form of off-road use.

Inseam (optional)

Units

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

Feet:

At 716mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2021 Suzuki Boulevard M90, 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.
