47 fields on record
The 2018 Triumph Bonneville Bobber is a factory bobber with a floating single seat and hidden rear suspension.

A low 690 mm seat, 228 kg wet weight and 10.6-litre tank give it a stripped-back look.

How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built primarily for stylish, relaxed cruising and short-to-medium rides where looks and feel matter as much as outright capability.
- Built for
- A torquey, characterful parallel twin wrapped in classic bobber styling, delivering relaxed, satisfying low-rev performance rather than high-rev thrills.
- Not ideal for
- Not suited to riders seeking sharp sport handling, long-distance touring comfort, or any off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
