For 2007 the Bonneville has an increased engine size of 865cc. This latest model also comes with a black engine and polished, lacquered engine covers and a span adjustment clutch lever.The Bonneville has excellent road manners and great agility in jammed city streets. The Bonneville’s road holding, handling and stopping ability is crisp, composed and confidence inspiring. The braking set-up of single front 310mm disc and 255mm rear, both worked on by powerful twin-piston calipers offers sensitivity and control.The Bonneville’s a great way to cover the urban landscape and equally at home blatting down a leafy country lane on a Sunday ride out.
A true roadster in every sense of the word, the Bonneville matches classic British style to 21st century technology. This pairing of authenticity with modernity has led the Bonneville to become an icon in its own right; world famous (and quintessentially British) designer Paul Smith has personally designed a signature series of Bonnies, with accessories to match. Triumph’s own sixty8 range, which includes hand crafted laptop bags, iPod holders and a series of unique custom-painted tank covers, further enhances the Bonneville’s status not only as a motorbike but also as a cool style statement.

The heart and soul of any motorbike is its engine, and the Speedmaster’s 865cc, DOHC, eight-valve, air-cooled parallel twin-cylinder engine uses a 270° crank firing interval, giving a throbbing beat and smooth, torque-laden power delivery. Both cylinders vent through a pair of deep-chromed slash-cut silencers while the satin black engine finish adds a crisp, understated edge to the handsome lines of what is a very distinctive and evocative power plant.
The riding position supports and ‘cups’ the rider into the gunslinger seat ready to launch at the horizon. Upper fork shrouds add even more style, while high risers mount the flat ‘drag’ handlebars on the slab-style top yoke and match the chromed forward set footpegs.
The Speedmaster wears a pair of cast wheels, with a crisp look all of their own; the 18 inch front wears a 110/80 tyre, the 15 inch rear a 170/80. The twin shocks and wide-style telescopic forks straighten the curves and iron out the bumps, giving a planted and supple ride. Twin 310mm front discs – gripped by twin-piston calipers – haul the Speedmaster up extremely hard.
If the Speedmaster’s bare bones want a little more flesh on them, the ever-expanding Triumph accessory range features an array of bolt-ons specifically designed to lend even more appeal and individuality.
