Triumph Bonneville Speedmaster 2018

Triumph Bonneville Speedmaster 2018

Even though the beach bar handlebars, the seat height of only 705 mm and the torque-heavy engine of the Triumph Speedmaster invite you to relax and glide with the classic cruiser, there is more speed in the latest Bonneville bike than you would expect. A 310 mm double-disc brake, generous suspension travel, adjustable levers as well as two riding modes and a traction control that can be switched off guarantee a rather sporty performance. But you really feel comfortable when you sit back and enjoy the deep roar of the British parallel twin - and maybe even let the cruise control do the work.
