A modern day roadster with a tangible connection to the classic style of times gone by, the Bonneville mixes timeless British engineering with modern technology and thinking. The result is captivating. As befits such an honest machine, at the core of the Bonneville is a sonorous and instantly recognisable 790cc, air-cooled, twin-cylinder engine. Laden with character - and with a distinct kick in its power delivery - the Bonnie engine entertains as much as it transports.
Matching the rugged motor is a chassis of substance. A massively strong, tubular steel, cradle frame, telescopic forks and disc brakes provide surefooted confidence while nimble steering geometry makes the Bonneville a sweet, neutral ride.
In an ever more complicated world sometimes the simple things bring the most pleasure. The Bonneville is an uncomplicated - and very real motorcycle that blends the old and new. It appeals because it looks, feels and sounds just as a motorcycle should.
Taking many cues from Triumph’s past - the original was first manufactured in 1959 - the Bonneville cleverly matches authenticity and tradition to modern needs and has found real relevance today with riders looking for a simple, honest and useful machine.
It’s an easy-to-manage motorcycle, thanks to a low seat height of 775mm - 30.5-inches - and similarly low centre of gravity. The sturdy frame and relaxed steering geometry provide composure at speed as well as ensuring the Bonnie needs only light input at the handlebars. Modern tyres and disc brakes front and rear add to the assured road-holding, handling and stopping ability. All riders - from those with little experience to those with lots - appreciate the Bonneville’s excellent open road manners and also its agility in jammed city streets.
The Bonnie’s air-cooled, 790cc parallel twin-cylinder engine offers a simple, striking look coupled with modern engineering techniques and materials. Both pistons rise and fall together - via a 360° crankshaft firing interval - giving the distinctive feel and character of a British twin-cylinder engine. The engine produces ninety percent of peak torque - a very healthy 60Nm - at 3,500rpm and maintains this figure through to the redline, providing smooth acceleration in any of the five gears.
Twin electrically heated 36mm carburettors feed the engine and are fitted with throttle position sensors. A pair of ’peashooter’ style silencers deal with exhaust gases and have a very traditional look, as does the triangular engine cover and left-hand side clutch casing, both quintessentially Triumph.
Three paint options - Aluminium Silver, Goodwood Green and Jet Black are available. The extra option of the black engine finish with the Jet Black paint adds a subtle alternative.
The Bonneville’s a stylish way to cover the urban landscape and is equally at home blatting down a leafy country lane on a Sunday ride out. It has a lineage few models can match and a tangible credibility. All of which makes the Bonneville as relevant today as it’s always been.
