Rider Profile

Best ForSuits riders from intermediate upward who want strong torque and classic styling without needing high-performance handling.
PurposeBuilt primarily as a stylish cruiser-style bobber for relaxed street riding and short scenic rides rather than sport or long-distance touring.
Rider FitLow seat height and manageable weight make it accessible, though limited suspension travel and a solo seat reduce comfort over rough roads or long stints.
CharacterA torque-rich, characterful classic twin that delivers strong low-end punch and a distinctive bobber stance with modern reliability.
Not Ideal ForNot a good fit for riders wanting off-road capability, sport-bike agility, or comfortable two-up long-distance touring.

2018 Triumph Bonneville Bobber Black Rider Ergonomics Assessment

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

Feet:

At 690mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2018 Triumph Bonneville Bobber Black, with a moderate knee angle of around 110 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.
