The most responsive Bonneville T120 twin yet. Weight reductions throughout the engine give the 2021 Bonneville a faster throttle pick-up with a much sharper feel.

With a strong, torque-rich delivery that starts low in the rev-range and climbs smoothly to a sizeable peak of 105Nm at just 3,500rpm, and with peak power of 80PS arriving at 6,550rpm, the flexible T120 is equally at home lazily surfing the torque or enthusiastically blasting between corners on your favourite back road.

The latest evolution of the T120 engine incorporates cutting-edge technical features, such as ride-by-wire throttle that gives the perfect connection between the rider’s right hand and the powertain, for a smooth, glitch-free power delivery at any engine speed, wherever you are in the slick six-speed gearbox.

Not only is the new 1200cc Bonneville engine lighter and more responsive, it also exceeds the latest Euro5 emissions regulations — and the expectations of everyone who rides it.


Triumph’s trademark neutral, easy-handling and engaging Bonneville riding experience just got better. With a substantial overall weight saving throughout the revised engine, together with new, lighter wheels, it’s our best handling T120 ever.
The reduced inertia from the lighter, classic 32-spoke aluminium rim wheels makes the 2021 Bonneville T120 nimbler through fast direction changes and gives a noticeable increase in acceleration.
Roadholding is assured with 120mm-travel 41mm cartridge front forks. Twin rear suspension units allow adjustment for preload to find the perfect ride for solo, pillion and luggage. Beautifully matched, the front and rear suspension give Triumph’s signature ride dynamic of agility and stability, comfort and control.
New Brembo twin-piston floating front calipers and dual 310mm discs give superb feel for confident braking in all conditions, with the added safety of the latest generation of ABS. Pirelli Phantom Sportscomp tyres, developed specifically for the T120, feature a classic tread design with modern levels of performance, offering superb rider feel and reassuring all-weather grip.


A whole host of additional modern technology has been beautifully incorporated to the T120 and T120 Black, including cruise control with easy-to-use, single-button operation which helps to increase comfort and reduce rider fatigue on long journeys.
The riding modes have also been enhanced, with the Road and Rain modes now adjusting the engine mapping and traction control settings for the ideal throttle response, whatever the riding conditions. As with the cruise control, the riding mode button is neatly incorporated into the new left-hand switch cube for easy operation and an uncluttered look to the Bonneville’s ‘bars.
Standard fit technology includes the latest generation of anti-lock braking system and a switchable traction control system for enhanced control and safety. With the Bonneville’s clean, classic styling always at the forefront of Triumph’s designers’ minds, these latest technological rider aids are compact, responsive and unobtrusive.

A high level of standard equipment and a premium specification brings real world practicality to Triumph’s most famous modern classic.
The comfortable low 790 mm seat and relaxed riding position make all-day rides effortless, while the daily commute is more grin and less grind with the torque-assist clutch that gives a light feel to the clutch lever without compromising feel and take-up on those stop/start urban rides. For peace-of-mind, an engine immobiliser is built into the ignition key for enhanced security.

A conveniently-located USB charging point is fitted beneath the seat so, whether you’re running low on phone battery or using a navigational device for your next big road trip, you can plug and play your way to your destination.
Further practicalities such as a centre stand kit for ease of maintenance, heated grips for those chilly rides and a pillion grab handle for improved comfort and safety are all available as Accessories and can be easily configured at the point of purchase.


Attention to detail and commitment to a premium finish are evident in both the T120 and T120 Black.
Both T120 models are enhanced by contemporary parts perfectly engineered for the ultimate modern classic. New Bonneville-branded clock faces clearly display a mix of analogue and digital information. A key design signature of the Bonneville, the 14.5 litre fuel tank, now gets new 3-bar chromed classic metal tank badges and traditional hand-painted coach lining for a premium finish that’s both unique and unmistakably Triumph.

The deep, lustrous paint finish and chrome detailing on the T120 are paired with beautiful brushed aluminium engine casings. The T120 Black benefits from equally durable, high-quality finishes, but with much more attitude. Set off by the distinctive dark brown seat, the blacked-out engine and exhaust are matched to black rims and headlamp bezel. Dark and foreboding, the moody and sophisticated colour options give the Black a completely different presence.
Crafted and refined details include machined cooling fins on the cylinder head and a high quality twin-skin brushed exhaust, which hides the innovative catalyst under the bike, whilst maintaining its beautiful flowing lines.
