Triumph Motorcycles has launched the new Bonneville T40 and Bonneville T4 in India, expanding its 350cc modern-classic lineup with prices starting at ₹2.55 lakh. Built in partnership with Bajaj, the entry-level retro roadsters combine traditional styling with modern liquid-cooled engines and advanced safety features, with deliveries slated to begin in late 2026.
Pricing, Bookings, and Delivery Timelines for India
Potential customers can secure either motorcycle via Triumph India’s official website by paying a nominal fee of ₹4,999. The lineup spans two core variants aimed at different price points within the entry-level classic segment.
The higher-spec Bonneville T40 carries an ex-showroom Delhi price of ₹2,79,999 (or ₹2.80 lakh depending on market region), while the more affordable Bonneville T4 is positioned at ₹2,54,999. Deliveries for the T40 are scheduled to reach dealerships and customers starting in November 2026. Buyers opting for the T4 will receive their motorcycles beginning in January 2027, with the T4 available in solid color options including Phantom Black, Carnival Red, and Competition Green.
Triumph has also structured ownership parameters around a 16,000 km or 12-month service interval, alongside a 14.5-litre fuel capacity.
Bonneville Engine Focuses on Accessible Drive
Underneath their retro bodywork, both motorcycles share an architecture derived from Triumph’s TR series, utilising a 350cc single-cylinder liquid-cooled engine paired with a six-speed transmission. Engineers gave the Bonneville range a dedicated tune and internal revisions that diverge sharply from sportier siblings like the Speed 400.
While the Tracker 400 and Thruxton 400 emphasize top-end urgency, the Bonneville heads in the opposite direction, focusing on accessible drive at everyday engine speeds, slower firing pulses, and a relaxed feel. The motor develops 29 horsepower (or 28.3 bhp to 28.6 bhp depending on regional specifications) at 7,000 rpm, alongside 31.2 Nm of torque at 5,500 rpm. Triumph also fitted smaller-diameter throttle bodies, dedicated camshafts, a revised cylinder head, and a traditional peashooter exhaust.
New Chassis Creates Quintessential Bonneville Aesthetic
The Bonneville T40 introduces a completely new chassis built specifically for the model. Unlike the aluminium swingarm and bolt-on subframe found on other single-cylinder Triumphs, the T40 features a tubular steel swingarm and a welded subframe designed to accommodate twin rear shock absorbers and get the quintessential Bonneville aesthetic right.
On the weighing scale, the T40 registers a kerb weight of 195 kg, making it substantially heavier than the 179 kg Speed 400. The styling package incorporates a teardrop-shaped fuel tank with rubber knee pads, a round LED headlight with a modern daytime running light signature, long mudguards, and wire-spoke wheels with tube-type tires.
Traditional proportions are further reinforced by fork gaiters, 43 mm conventional telescopic forks at the front, and twin rear shock absorbers featuring seven-step preload adjustment. The standard Bonneville T40 comes in three unique two-tone color schemes: Aegean Blue paired with Fusion White, Meriden Blue with Tangerine Orange, and New England White combined with Jet Black. A T40 Black variant adopts Matt Pewter Grey and Matt Phantom Black treatments alongside blacked-out components and gloss-black wheel rims.
Technology Packages: T40 Versus T4
The primary differentiator between the two new models lies in their electronics suite and instrumentation. The T40 is equipped with a four-inch full-colour TFT display featuring full-map navigation, speed-limit information, saved destinations, and points of interest that can be imported via GPX files. It also includes five riding modes (Road, Rain, Eco, and additional custom settings), cruise control, and lean-sensitive Optimised Cornering ABS and Traction Control.
The lower-tier Bonneville T4 retains the same mechanical foundation, chassis, and three basic riding modes (Road, Rain, and Eco), but swaps out the TFT console for a simpler colour LCD unit. While the T4 still offers Bluetooth connectivity, turn-by-turn navigation, and call management through handlebar controls, it misses out on lean-sensitive rider aids, though it does include an Emergency Deceleration Warning in its safety package alongside dual-channel ABS.
Triumph Classics Compete with Established Retro Models
Priced around ₹2.55 lakh to ₹2.80 lakh, Triumph’s new entry-level classics land squarely in territory dominated by established single-cylinder retro models. Industry observers note that the Royal Enfield Classic 350 and Honda CB350 represent the primary benchmarks in this displacement class.
While competitors rely heavily on traditional air-cooled or air-oil-cooled architectures—with Royal Enfield’s Classic 350 producing 20.5 PS and 27 Nm paired with a five-speed gearbox—the Triumph lineup counters with liquid cooling, a six-speed transmission, and a comprehensive electronics suite. Potential customers can secure either motorcycle via Triumph India’s official website by paying a nominal fee of ₹4,999.
