The new Triumph Bonneville T40 and T40 Black has finally been unveiled along with an even more bare bone Bonneville T4 version. These new bikes are designed to bring the classic Bonneville riding experience to an even broader audience by blending traditional 1960s cool with modern tech and an entry-level 350cc powerplant.
Developed alongside Bajaj, the two models join Triumph’s globally successful 400 series platform—which already features the Speed 400, Scrambler 400 X, Scrambler 400 XC, Tracker 400, Thruxton 400, and Speed T4.

The single-cylinder engine features a lower idle speed and a peashooter silencer designed to deliver a deep, distinctive exhaust note with clear firing pulses.
Riders can choose from three pre-configured riding modes (Road, Rain, and Eco) alongside two customisable modes. Each mode adjusts the throttle response, traction control, and ABS. These settings can be added to a quick-access menu managed via backlit switch cubes on the left handlebar.
Timeless Design with Exceptional Detail
The new T40 and T40 Black carry over all the classic design cues that define the Bonneville silhouette:
- A sculpted teardrop fuel tank complete with classic rubber knee pads and the iconic three-bar Triumph badge.
- A traditional round LED headlight featuring a distinctive daytime running light (DRL) signature that switches automatically to dipped beam.
- Traditional spoked wheels pairing an 18-inch front and a 17-inch rear lightweight aluminium rim with steel spokes.
- Heritage styling details including a ribbed bench seat, longer mudguards, classically styled front forks, and twin rear shocks.
To keep the aesthetic clean, modern engineering like cables and hoses are hidden from view. Authentic touches like hand-painted coach lining on deep paint finishes, brushed peashooter silencers, and classically shaped aluminium engine covers with bright machined cooling fins further elevate the build. Branding is subtly integrated, appearing on engine covers, within the lights, and embossed into the front mudguard and handlebar clamp.
