Rider Profile

Best For	Suits new-to-intermediate riders thanks to modest power delivery and forgiving, predictable handling.
Purpose	Best suited to relaxed street riding, café-racer style cruising, and short scenic rides rather than outright performance.
Rider Fit	A moderate curb weight and low, accessible seat height make it manageable for riders of average build and shorter inseams.
Character	A classic-styled retro roadster that prioritizes timeless looks, mellow torque, and easygoing manners over speed or sharpness.
Not Ideal For	Not a good fit for riders wanting high-speed touring, aggressive cornering performance, or any off-road capability.

Units

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

Feet:

At 775mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2005 Triumph Bonneville, 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.
