Triumph unveils new 350cc Bonneville lineup with three distinct variants

Triumph has introduced its new 350cc Bonneville range in India, built around the same liquid-cooled single-cylinder platform used in the brand's '400' portfolio. The new lineup includes three models named the T4, T40, and T40 Black. Out of these, the entry-level T4 is sold only in India, while the T40 and T40 Black serve as global models.

Variant Details

The India-exclusive T4 is priced at Rs 2.55 lakh, which is Rs 25,000 less than the T40. It keeps the same mechanical setup as the T40 but features fewer electronics. It replaces the 4-inch TFT screen with a colour LCD display, removes cruise control, and drops the IMU, switching lean-sensitive ABS to standard dual-channel ABS. Buyers can choose from three solid colours of green, black, and red, with deliveries starting in the second week of January 2027. Meanwhile, the T40 costs Rs 2.80 lakh and acts as the standard international-spec version. It features a new round 4-inch colour TFT display with five riding modes called Road, Rain, Eco, and two customisable modes. It also includes traction control, cruise control, and lean-sensitive ABS. A Heritage display layout provides an old-school look, and riders can connect their phones using the Triumph Navigation app for turn-by-turn directions. Deliveries for the T40 begin in November 2026. The T40 Black also costs Rs 2.80 lakh and shares the exact same feature list as the standard T40. Its only unique difference is the use of blacked-out engine and cycle parts. Deliveries for this version are also expected to start in November 2026.

Shared Specs

All three motorcycles run on a reworked 350cc liquid-cooled single-cylinder engine that features a revised cylinder head, smaller throttle bodies, dedicated camshafts, and a new peashooter exhaust. This engine makes 29 horsepower at 7,000 rpm and 31.2 Nm of torque at 5,500 rpm, tuned specifically for strong low- and mid-range performance. The frame is shared across the range too, featuring a new rear frame with a welded subframe, a tubular steel swingarm, a 43mm right-way-up fork, and twin rear shocks. Stopping power comes from a 310mm front disc with a twin-piston axial caliper and a 255mm rear disc with a single-piston caliper.

Context

Motorcycle manufacturers often introduce region-specific variants to match local pricing expectations and market demands. Sharing engine platforms across multiple models helps companies lower production costs while offering varied styling and feature sets.
