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 350cc Engine Specs Leak Ahead of India Launch Triumph Motorcycles has faced a surge of anticipation as leaked specifications for its upcoming 350cc iterations of the Speed, Scrambler, and Thruxton 400 models have surfaced online ahead of their official launch in India on 6 April. The details, which include power and torque figures, suggest a subtle yet significant shift in the performance characteristics of these motorcycles compared to their 398cc counterparts. While the power output remains relatively close to the 400cc range, the torque reduction and higher-revving nature of the 350cc engine are expected to alter the riding experience, potentially requiring more frequent gear changes in stop-and-go traffic. The leaked data reveals that the 350cc engine in the Speed T4 model is projected to deliver 28.6Nm of torque at 7,500rpm and peak power of 31Nm at 5,500rpm. This represents a decline of 2bhp and 5Nm compared to the existing 398cc version. Performance metrics have also seen marginal adjustments, with the 0-60kmph time dropping to 3.5 seconds and 0-100kmph time extending to 9.6 seconds. The top speed of the Speed T4 is expected to decrease from 141.4kmph to 137kmph. For the 350cc-powered Speed 400 and Scrambler 400 X/XC models, the engine is anticipated to produce 36.5bhp at 8,500rpm and 32Nm of torque at 7,000rpm. This contrasts with the 398cc unit, which generates 39.5bhp at 8,000rpm and 37.5Nm at 6,500rpm. The reduction in torque is more pronounced here, with a 5Nm drop, while the power output remains slightly lower. The Thruxton 400, in its 350cc configuration, is expected to deliver 39.5bhp at 8,750rpm and 32Nm of torque at 7,500rpm. This compares to the current 398cc model, which produces 41.5bhp and 37.5Nm.#speed_400 #triumph_motorcycles #speed_t4 #scrambler_400_xxc #thruxton_400
