Triumph has expanded its Bonneville family in India with three new motorcycles: the Bonneville T40, T40 Black and T4. Prices start at Rs 2.80 lakh (ex-showroom, Delhi) for the T40 and T40 Black, while the T4 is more affordable at Rs 2.55 lakh (ex-showroom) thanks to its simpler electronics package.
These are the smallest Bonneville models Triumph has introduced so far. All three use the company’s 350cc single-cylinder TR Series engine, which produces 29PS. Bookings will open tomorrow at 4:30pm, with deliveries of the T40 and T40 Black scheduled to begin in the second week of November. The T4 will reach customers from the second week of January 2027.
Triumph Bonneville T40: Engine And Chassis
The 350cc, liquid-cooled single-cylinder engine produces 29PS at 7,000rpm and 31.2Nm at 5,500rpm. It comes paired with a six-speed gearbox and a slip-and-assist clutch, while fuel injection and electronic throttle control are supplied by Bosch.
Although the T40 shares its basic engine architecture with Triumph’s other 350cc motorcycles, it gets several changes to suit the Bonneville character. These include a revised cylinder head, smaller throttle bodies, dedicated camshafts and a new exhaust system. Triumph has also given the engine a specific tune aimed at delivering stronger torque lower down the rev range. The gearing is taller as well.
The motorcycle uses a tubular steel frame with a redesigned rear section for the twin-shock setup. It also gets a tubular steel swingarm, while the subframe is welded directly to the main frame rather than being bolted on.
Up front, suspension duties are handled by a 43mm gaiter fork, while the rear gets twin preload-adjustable shocks. Both ends offer 130mm of wheel travel. Braking comes from a 310mm front disc with a twin-piston caliper and a 255mm rear disc. Cornering ABS is also available.
The T40 rides on 18-inch front and 17-inch rear spoked aluminium wheels, wrapped in tubed MRF tyres. The standard seat height is 790mm, although an optional low seat brings it down to 770mm. The motorcycle weighs 195kg in wet form, has 165mm of ground clearance and gets a 14.5-litre fuel tank. A centre stand and upper engine protection bars are standard.
Bonneville T40 Design And Features
The Bonneville T40 gets the classic styling associated with the name. There is a teardrop-shaped fuel tank with rubber knee pads and the traditional three-bar Triumph badge, along with a round LED headlight featuring a distinctive daytime running light signature.
The motorcycle also gets longer mudguards and a peashooter-style exhaust. Details such as the machined cylinder-head fins and brushed aluminium clutch and alternator covers add to the retro look.
Triumph says every T40 is finished by hand, including hand-painted coach lining on the fuel tank. The standard T40 is available in three two-tone combinations: Aegean Blue with Fusion White, Meriden Blue with Tangerine Orange, and New England White with Jet Black.
The bike also gets chrome mirrors and a chrome grab hoop, along with brushed aluminium heel guards and a brushed steel exhaust.
The T40 Black, as the name suggests, takes a darker approach. It comes finished in Matt Pewter Grey and Matt Phantom Black, with gloss-black rims, steel spokes, powder-coated engine casings and several blacked-out components.
T40 Gets Modern Electronics
Despite its classic appearance, the T40 gets a fairly modern electronics package. It features a new 4-inch circular TFT display with a Heritage mode that gives the screen an analogue-style appearance.
Navigation is handled through Triumph’s new Navigation App, which supports route planning, waypoints and GPX imports. Riders can also control phone calls and music through the system.
Other equipment includes self-cancelling indicators, Emergency Deceleration Warning and a USB-C charging socket.
The Bonneville T40 also gets five riding modes: Road, Rain, Eco and two customisable modes. These alter throttle response, traction control and ABS settings depending on the selected mode.
Cruise control and Cornering Traction Control are standard on the T40 and T40 Black.
Service And Accessories
Triumph has set service intervals at 16,000km or 12 months, whichever comes first. Buyers will also be able to choose from accessories including low and comfort seats and classic panniers.
Triumph Chief Product Officer Steve Sargent said the company wanted the T40 and T40 Black to offer more than just a smaller Bonneville. According to the company, the focus was on retaining the design details and character associated with the Bonneville while adding modern technology and making the motorcycle accessible to a wider group of riders.
With the new T40, T40 Black and T4, Triumph is essentially bringing its Bonneville formula into a smaller and more accessible segment without giving up the styling and character that have defined the name for decades.
