Triumph Bonneville Bobber 2021

The Triumph Bobber 2026 is the quiet queen of coolness. It doesn't need top values to shine, but shines with composure, torque and mechanical honesty. The Speedmaster counters this with the same genes in a different body: more comfortable, more majestic, with clear limits to the sporty radius. Together, they make a pair that you won't think of leaving the garage once you've ridden one. For soloists who want to breathe style, it's the Bobber. For connoisseurs seeking wide horizons without haste, it's the Speedmaster. And for all those who have both, the common denominator has finally been found.

superior torque curve

very low seat height with a lot of confidence

unobtrusive, effective electronics

high-quality feel of controls

stable, relaxed suspension on the country road
