Triumph Bonneville 400, being the seventh model in the 400 range, will directly lock horns with Royal Enfield Classic 350 in India
Triumph Bonneville 400 is inching closer to its market launch in India. Scheduled to go on sale around Sep-Oct 2026, it has been captured on camera once again on the Indian roads. The upcoming Triumph Bonneville 400 will be a retro classic motorcycle which will directly rival Royal Enfield Classic 350 in the Indian market. The latest set of spy images reveal that the bike will also get a new swingarm and revised chassis. The rear subframe is also likely to be restyled for the flat bench-type seat and Bonneville silhouette.
The Bonneville 400 appears to be quite massive as compared to the Speed 400. The fuel tank is bigger while the side panels are rounded and long. The front and rear fenders are quite thick and heavy for an enhanced road presence. The British brand has kept the old-school charm intact by introducing multiple chrome-studded elements in the form of peashooter exhaust, engine crankcase covers, and rear grab rails.
Riding on wire-spoke wheels, the overall styling of the new Triumph bike is inspired by the bigger Bonneville models of 900cc and 1200cc as the old-school charm of these iconic cruiser motorcycles is visible in the smallest Bonneville till date. The retro classic appearance is further accentuated by circular LED headlamp, belly pan, teardrop-shaped fuel tank, and lower handlebars.

The Bonneville 400 would use traditional elements instead of premium cycle parts as we see in the Speed 400. It will boast of telescopic front forks in place of the Speed 400’s USD front suspension. At the rear, the bike will have twin-shock absorbers and to accommodate this setup, the brand is likely to use a new subframe and swingarm as mentioned earlier in this piece.
The stopping power will come from front and rear disc units, which will be assisted by a dual-channel ABS. Interestingly, the Bonneville 400 houses a circular instrument cluster as compared to the semi-circular unit seen in the Speed 400. At the heart, the India-spec Bonneville 400 would be packed with the new 349cc single-cylinder liquid-cooled engine which generates max power of 36.5 bhp and peak torque of 32 Nm with the Speed 400 and Scrambler models.

These power and torque figures are expected to be retained with the Bonneville 400. The engine will be paired with a 6-speed gearbox. The Bonneville would be the seventh 400 motorcycle in the British brand’s portfolio after the Speed T4, Speed 400, Scrambler 400X, Scrambler 400 XC, Thruxton 400 and Tracker 400.
