Rider Profile

Best ForBest suited to experienced riders who are comfortable managing a very heavy, long-wheelbase machine with a massive rear tyre at low speeds.
PurposeBuilt for boulevard cruising and making a visual statement, with a huge torque-rich V-twin that delivers strong roll-on power rather than track-focused performance.
Rider FitIts low seat height suits shorter riders but the substantial dry weight and wide, fat rear tyre demand good upper body strength for slow-speed maneuvering and U-turns.
CharacterA muscular power-cruiser character defined by deep torque, a dominant V-twin exhaust note, and imposing custom styling rather than nimble handling.
Not Ideal ForNot for riders seeking agile cornering, off-road capability, or a lightweight bike for tight city filtering.

2015 Suzuki Intruder M1800RB Rider Ergonomics Assessment

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

Feet:

At 705mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2015 Suzuki Intruder M1800RB, 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.
