Rider Profile

Best ForWell suited to newer and returning riders thanks to its approachable parallel-twin character and predictable, classic-styled handling.
PurposeBuilt primarily as a classic-styled roadster for relaxed commuting, weekend rides, and casual cruising rather than outright performance.
Rider FitA moderate, upright seating position and manageable width and height make it accessible to riders of average and smaller stature.
CharacterOffers a timeless, retro British roadster feel with smooth, torquey power delivery and easygoing, confidence-inspiring manners.
Not Ideal ForNot the right choice for riders seeking aggressive sportbike speed, track-day performance, or serious off-road capability.

2009 Triumph Bonneville T100 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 2009 Triumph Bonneville T100, 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.
