Does the Triumph Bonneville Speedmaster fit you?
The Triumph Bonneville Speedmaster (2018–2020) has a 711 mm seat height. As a rule of thumb, riders with an inseam around 71 cm — roughly 151 cm (4'11") tall — can plant both feet flat at a stop. Around 65 cm inseam you'll be on the balls of your feet, and shorter riders will tiptoe. Enter your own height and inseam in the simulator above to see exactly how you reach the ground on the Triumph Bonneville Speedmaster.
Riding position
As a cruiser motorcycle, the Triumph Bonneville Speedmaster puts you in a relaxed, feet-forward stance. The simulator scores the exact knee, hip, and elbow angles for your body so you can see how relaxed or aggressive the reach to the bars and pegs will feel.
What is the Triumph Bonneville Speedmaster best for?
The Triumph Bonneville Speedmaster is best suited to relaxed, low-seat cruising with a feet-forward stance and easy reach to the ground.
Fit figures are rules of thumb (flat-foot inseam ≈ seat height); the simulator gives your exact reach and joint angles. Braking is an estimate from wet weight and wheelbase on a dry road.
