Rider Profile

Best ForBest suited to experienced riders who are comfortable managing a very heavy, torque-laden machine at low speeds.
PurposeBuilt as a muscle cruiser that delivers massive straight-line thrust and effortless overtaking power rather than nimble cornering.
Rider FitIts 320kg dry weight and low seat height demand strength and confidence at parking-lot speeds, though the low center of gravity helps once rolling.
CharacterA brawny, torque-dominant cruiser whose enormous inline-triple engine defines the riding experience with relentless low-end pull.
Not Ideal ForNot a good fit for riders seeking a lightweight, flickable bike for tight twisties or off-road adventures.

2009 Triumph Rocket III Rider Ergonomics Assessment

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

Feet:

At 740mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 Triumph Rocket III, 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.
