Rider Profile

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

2006 Triumph Bonneville Rider Ergonomics Assessment

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 2006 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.
