Triumph Blends Modern Tech and Classic Looks with New Bonneville T40 Bikes
The Triumph Bonneville is an undeniably classic motorcycle that’s capable of stirring nostalgia even in those too young to have actually ridden the original ‘60s machines. Now Triumph has announced a duo of new Bonneville motorcycles that aim to marry the bike series’ classic looks with modern performance and tech.
The Triumph Bonneville T40 and T40 Black are the latest additions to the renowned motorcycle lineup. Their designs incorporate many classic Bonneville elements—a teardrop fuel tank, round headlight, spoked wheels, and twin-shock rear suspension—while adding a next-generation engine and electronic rider aids.
Powering the T40 bikes is Triumph’s newest liquid-cooled 400cc single-cylinder TR Series engine. The company promises a maximum power output of 30 hp at 7,000 rpm, while the maximum torque of 26.5 lb-ft is delivered at 5,000 rpm. A six-speed gearbox modulates the engine’s performance.
The chassis is a hybrid spine/perimeter tubular steel frame with a twin-sides steel swingarm. Triumph has set the seat height at 31.1 inches, with an accessory low seat that further reduces that to 30.3 inches. With the 3.8-gallon teardrop tank filled, the Bonneville T40 duo clocks in at 421 pounds.
Suspension consists of a 43mm unadjustable fork and the aforementioned twin shocks with preload adjustment. Both offer a decent 5.1 inches of travel, which should suffice for most city streets and well-maintained backroads.
Stopping power stems from a single 310mm disc up front with a twin-piston axial caliper and a 254mm disc with a single-piston caliper in the rear.
Moving on to the electronics, Triumph has done its best to make the bike seem like it has no electronic aids. The control interface is embedded into the round, full-color, four-inch TFT display that mimics the appearance of the original Bonneville’s instrument clusters. Those who want the authentic look can swap the display to Heritage Mode, where it shows analog-style needles.
The T40s feature three preconfigured ride modes (Road, Rain, and Eco) and two custom modes that adjust throttle response, traction control, and ABS. To make swapping between the modes easier, the display features five quick-select slots for saving your preferred settings.
Cruise control is standard on both motorcycles, as are cornering-ABS and traction control. For connectivity, the round display supports the Triumph Navigation App for route planning and turn-by-turn directions, in addition to phone connectivity, media playback, and more.
In styling and appearance, the T40s are unmistakably Bonnevilles. Triumph has done a great job preserving that old-timey Bonneville charm (yes, it’s old by now) with the lines of the gas tank, chassis, and engine geometry. The company also says each bike is finished by hand with final finishes on the paint job.
Speaking of paint, the only difference between the Bonneville T40 and T40 Black is color. The T40 features chrome-finished components, while the T40 Black comes with (surprise, surprise) blacked-out, powder-coated surfaces.
The Bonneville T40 comes in Meriden Blue/Tangerine Orange and New England White/Jet Black paint schemes. Its dark sibling is available in Matt Pewter Gray/Matt Phantom Black.
According to Triumph, the motorcycles will arrive at dealerships in spring 2027. Pricing information had not been announced at the time of writing.
