Triumph Bonneville 400 Spotted Testing in India A retro-styled Triumph 400 motorcycle has been spotted undergoing testing in India, signaling the brand’s expansion into the classic roadster segment. The new model, likely to be named the Bonneville 400, is expected to join the existing Speed 400 and Scrambler 400 X variants in Triumph’s small-displacement lineup. The test mule has revealed significant design and mechanical changes, positioning the bike as a direct competitor to Royal Enfield’s Classic 350 and Bullet 350 models. The Bonneville 400 is anticipated to launch in the second half of 2026, aligning with the festive season in India. Key hardware updates include a twin-shock rear suspension setup, which requires a redesigned rear subframe to accommodate the classic aesthetic. The engine casing and exhaust system feature a brushed aluminum finish with chrome accents, evoking a vintage look. However, international testing has shown variations, with some units sporting a black powder-coated engine casing and exhaust. The bike also includes a factory-fitted center stand, a first for a Triumph 400 model. Design-wise, the Bonneville 400 adheres to traditional roadster proportions, featuring a flat, single-piece seat and an integrated chrome grab rail. The rear section appears nearly production-ready, though the tail-light unit remains uninstalled on the test mule. The front end incorporates new switchgear and an instrument console, though the type of display—whether a TFT unit or a reverse-LCD setup—remains unclear. Powering the Bonneville 400 is a downsized 349cc single-cylinder engine, derived from the 398cc unit used in the recently launched Speed T4. This engine produces 29 horsepower and 31 Nm of torque, paired with a six-speed gearbox.#india #royal_enfield #triumph_motorcycles #bonneville_400 #speed_t4
Triumph Bonneville-style 400cc motorcycle spotted undisguised ahead of debut The upcoming Triumph Bonneville 400 has been revealed in its unmasked form, offering a first look at its retro-inspired design and updated mechanical components. The motorcycle, part of Triumph’s expanding small-displacement lineup, features a classic roadster aesthetic with elements borrowed from larger Bonneville models. Its design includes a metal fuel tank, a round headlamp, and a long single-piece seat, positioning it as a departure from the sportier looks of existing 400cc Triumph offerings. Additional retro touches such as wire-spoke wheels, a redesigned radiator grille, and an underbelly guard further emphasize its vintage character. This marks the first Bonneville-style motorcycle built on the 400cc platform developed through the Bajaj-Triumph partnership. The model is expected to compete with rivals like the Royal Enfield Classic 350 and Jawa Jawa, broadening Triumph’s presence in the compact motorcycle segment. The Bonneville 400’s design shifts toward a more relaxed, classic roadster profile, contrasting with the aggressive styling of current 400cc models. Key hardware changes include a dual rear shock absorber setup, replacing the monoshock configuration used on other Triumph 400cc models. This modification is likely to alter the motorcycle’s ride dynamics and visual appeal. The swingarm has also been revised to accommodate the new suspension layout. At the front, the disc brake has been moved to the right side of the wheel, a departure from the left-mounted setup on existing models. A new instrument cluster is also visible, though its functionality remains unconfirmed. The engine is expected to retain the same unit used in the Triumph Speed 400, producing 40 bhp and 37.5 Nm of torque.#triumph #royal_enfield #bonneville_400 #jawa #bajaj_triumph
