Triumph has introduced the T40 and T40 Black, expanding its Bonneville lineup into the 350cc class. Both models feature a liquid-cooled 350cc single-cylinder engine developed in partnership with Bajaj. The engine delivers 29 PS at 7,000 rpm and 31.2 Nm of torque at 5,500 rpm, with tuning optimized for low-end responsiveness suitable for daily riding. The motor is designed to meet A2 licence requirements and produces a distinctive firing sound through a peashooter silencer.
The T40 equipped with standard electronics includes a four-inch circular TFT display that integrates navigation via the Triumph Navigation App, along with phone and music controls. Riders can switch to an analogue-style Heritage Mode for a classic appearance. Five riding modes, Road, Rain, Eco and two customizable, complement cruise control, cornering-sensitive ABS, traction control, LED lighting, self-cancelling indicators, Emergency Deceleration Warning and a USB-C charging port.
Styling adheres to Bonneville tradition with a teardrop tank, round LED headlight, twin rear shocks and spoked wheels measuring 18-inch front and 17-inch rear. Hand-finished details include brushed aluminium engine covers and coach lining. The standard T40 offers three two-tone color schemes: Aegean Blue with Fusion White, Meriden Blue with Tangerine Orange, or New England White with Jet Black, complemented by chrome mirrors and a brushed steel exhaust. The T40 Black features Matt Pewter Grey and Matt Phantom Black paint, gloss-black rims and powder-coated engine casings.
