Triumph Bonneville T40 and T40 Black: the Bonnie becomes more affordable

Triumph is targeting newcomers and those returning to motorcycling after many years, and is unveiling two new versions of the legendary Bonneville – the iconic British roadster – with a more accessible engine capacity. At the heart of the Bonneville T40 and T40 Black, in fact, is the evolved 400 cc Tr Series single-cylinder engine, developed to deliver smooth power delivery, plenty of torque at low revs and a character true to the Bonneville tradition (read the Bonneville T120 Black test ride ). The design incorporates all the elements that have made the range famous: teardrop fuel tank, round headlight, spoked wheels, twin rear shock absorbers and a peashooter-style exhaust. The T40 embraces a classic aesthetic, with two-tone paintwork and hand-finished details, whilst the T40 Black reinterprets the same concept in a more contemporary style, thanks to the dark finishes on the engine, exhaust and components.

Single-chamber heart

The liquid-cooled, four-valve single-cylinder engine, featuring a redesigned cylinder head and specific mapping, delivers 32 cv at 7,000 rpm and 36 Nm at 5,000 rpm. Three riding modes – Road, Rain and Eco – are complemented by two customisable settings, which adjust the throttle response and electronic systems. ABS and cornering traction control are also included, as well as cruise control.

Classic and high-tech

The tech features are one of the most interesting aspects. Behind the classic look lies a 4-inch circular TFT colour display, with a ‘Heritage’ mode that reproduces graphics inspired by analogue instrumentation. Smartphone connectivity, navigation with comprehensive maps, call and music management, and customisable widgets round off a range of features normally associated with motorcycles in a higher category. The chassis has been designed to prioritise ease of use and comfort. The riding position is upright; the seat height is 790 mm and can be lowered to 770 mm with the lowered seat. The kerb weight is 191 kg, whilst the 18-inch front and 17-inch rear wheels contribute to the bike’s manoeuvrability. Braking is provided by a front disc with a two-piston caliper. The new Bonneville T40s are also compatible with a range of genuine accessories, including comfort and lowered seats and panniers.
