Rider Profile

Best ForWell suited to newer and experienced riders alike thanks to its predictable power delivery and confidence-inspiring low-speed manners.
PurposeBuilt as a classic-styled roadster for relaxed cruising, weekend rides, and everyday commuting rather than outright performance.
Rider FitA substantial 263kg wet weight combined with a low seat height makes it manageable at a stop but requires deliberate effort in slow maneuvers and parking.
CharacterDelivers a torquey, characterful parallel-twin experience with classic British styling and modern underpinnings for smooth, unhurried riding.
Not Ideal ForNot the right choice for riders seeking sharp sportbike handling, high-speed thrills, or any serious off-road capability.

Rider Fit Visualizer

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

Feet:

At 790mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2020 Triumph Bonneville T120 Black, with a relaxed knee angle of around 120 degrees and a forward-leaning 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.
