Rider Profile

Best For	Suitable for riders with at least some experience handling a heavy, torque-heavy cruiser, though the low seat height and manageable power delivery make it approachable for confident newer riders too.
Purpose	Built for relaxed, torque-driven cruising and long highway stints rather than outright speed or cornering agility.
Rider Fit	The low 700mm seat height helps shorter riders plant their feet, but the 308kg dry weight demands good low-speed balance and strength when maneuvering or parking.
Character	A big, laid-back British cruiser with strong low-end torque, a deep exhaust note, and a commanding, classic custom presence.
Not Ideal For	Not a good fit for riders wanting sharp handling, off-road capability, or high-speed sport performance.

Units

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

Feet:

At 700mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2017 Triumph Thunderbird, with a cramped knee angle of around 75 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.
