Expanding its modern-classic footprint in India, Triumph Motorcycles has introduced two new models in the sub-middleweight category: the Bonneville T4 and the Bonneville T40. These additions bring the British marque's signature Bonneville heritage styling down to a more accessible 350cc platform, setting up a direct challenge against established rivals like the Royal Enfield Classic 350 in the domestic retro motorcycle market.
Pricing, Variants, and Delivery Timelines
The lineup begins with the Triumph Bonneville T4, priced at an ex-showroom Delhi figure of Rs 2,54,999. Buyers looking for higher styling specifications can opt for either the T40 or the T40 Black, both commanding an ex-showroom tag of Rs 2,79,999. Online reservations across the range open tomorrow through the official brand portal. Customers booking the T40 and T40 Black can expect deliveries to commence in the second week of November 2026, whereas dispatches for the standard T4 variant will start in the second week of January 2027.
Engine Architecture and Performance Specs
Powering both motorcycles is a newly developed liquid-cooled 350cc TR-series single-cylinder engine. Benefiting from dedicated tuning and an updated cylinder head design, the motor delivers between 28.6 and 29 bhp of power at 7,000 rpm, alongside 31.2 Nm of peak torque at 5,500 rpm. The power delivery characteristics are calibrated specifically to offer solid tractability in low and mid-range engine speeds. A six-speed gearbox paired with an assist-and-slipper clutch manages power transfer to the rear wheel, while maintenance requirements are supported by a wide 16,000-kilometre service schedule.
Heritage Aesthetics and Chassis Ergonomics
Aesthetic highlights stay faithful to traditional Bonneville design codes, incorporating a teardrop-shaped 14.5-litre fuel tank, a round LED headlamp, peashooter silencers, and spoked wheels sized 18 inches at the front and 17 inches at the rear. The T40 distinguishes itself further with two-tone heritage paint schemes accented by hand-painted pinstriping. Saddle ergonomics feature an accessible 790 mm standard seat height, which riders can lower to 770 mm using an optional accessory saddle. Overall motorcycle kerb weight ranges between 191 kg and 195 kg.
Rider Aids and Hardware Equipment
Despite their vintage exterior, both machines pack contemporary riding technology centred around a 4-inch circular TFT display compatible with smartphone connectivity and navigation prompts. Riders can select between Road, Rain, and Eco engine maps alongside two user-customisable profiles. Cruising long stretches is aided by standard cruise control, complemented by safety hardware like lean-sensitive cornering ABS and traction control. Anchoring duty is performed by a 310 mm front disc brake and a 255 mm rear disc rotor, supported by a twin-shock rear suspension configuration and a standard centre stand.
