Triumph has revealed its 350cc Bonneville range for India, sharing its 350cc liquid-cooled single-cylinder platform with the rest of the ‘400’ portfolio. Three variants make up the lineup – the T4, T40 and T40 Black – with the entry-level T4 sold exclusively in India and the T40 pair serving as the globally available models. Here’s what separates them.
350cc Triumph Bonneville variant breakdown
Bonneville T4
The T4 is the India-exclusive entry point into the Bonneville range, priced Rs 25,000 below the T40 at Rs 2.55 lakh. It is mechanically identical to the T40 but steps down on electronics – a colour LCD display replaces the T40’s 4-inch TFT, and it drops cruise control and the IMU, which means lean-sensitive ABS gives way to standard dual-channel ABS. It is available in three solid colours: green, black and red with deliveries set to begin the second week of January 2027.
Bonneville T40
At Rs 2.80 lakh, the T40 is the standard international-spec model. It debuts a new round 4-inch colour TFT display with five riding modes – Road, Rain, Eco and two fully customisable modes – traction control, cruise control and lean-sensitive ABS. A Heritage display layout gives the console a more old-school appearance, and pairing a phone via the Triumph Navigation app brings turn-by-turn navigation to the screen. Deliveries begin November 2026.
Bonneville T40 Black
Priced identically to the T40 at Rs 2.80 lakh and carrying the same full feature set, the T40 Black is distinguished solely by blacked-out engine and cycle parts. Deliveries are also expected in November 2026.
All three variants share the same reworked 350cc liquid-cooled single – fitted with a revised cylinder head, smaller throttle bodies, dedicated camshafts and a new peashooter exhaust – producing 29hp at 7,000rpm and 31.2Nm at 5,500rpm, tuned for a torque-rich low- and mid-range. The chassis is also shared with a new all-rear frame with a welded subframe and tubular steel swingarm, a 43mm right-way-up fork, and twin rear shocks. Braking comes from a 310mm front disc with a twin-piston axial caliper and a 255mm rear disc with a single-piston caliper.
