The sheer simplicity of the Bonneville form, matched to Triumph's modern engineering integrity has introduced a whole new generation to the charms of one of motorcycling's most enduring icons. And to add further authenticity to the Bonneville legend, Triumph has kept the 'Bonnie' as true to its 50's roots as a modern masterpiece deserves.

Traditional parallel twin power doesn't come any punchier or more refined than that of the 790cc Bonneville unit. Equipped with a 360 degree crankshaft to reproduce the classic engine beat of a British twin (where both pistons rise and fall together), there's plenty of power (61bhp at 7400rpm) and a remarkable 90 per cent of peak torque (60Nm) from 2750rpm all the way to the redline. Twin balancer-shafts keep vibration to a minimum and further refine the relaxed riding experience.

The engine is fed by twin 36mm carburettors with throttle-position sensors, electrically-heated, while the exhaust system employs secondary air-injection to keep emissions low and exits via traditional twin 'peashooter' silencers. The unmistakably Triumph triangular engine cover and left-side clutch case remain brushed and lacquered for 2003.

Sure-footed at speed, yet easy-steering and manoeuvrable around town, the low centre of gravity and minimal 775mm (30.5in) seat height allow the rider to get the best from the light yet substantial tubular steel double cradle frame and box-section swing-arm.

With modern rubber mounted on a 19 inch front and 17 inch rear wheel, and with disc brakes front and rear, the outwardly traditional chassis can more than cope with the modern levels of performance meted out by the motor. In fetchingly simple single-tone tank colours for 2003, the authentic answer to tradition matched to the modern age is a purer experience than ever.
