Triumph previews Bonneville 400 prototype on Polish road

Triumph Motorcycles has shown a near‑final version of the Bonneville 400, the next model in its Modern Classic lineup aimed at riders with an A2 licence. Spy photos taken by digital creator mane_the_omkar captured the bike circulating on a main thoroughfare in a Polish city.

The prototype retains the retro styling of the Bonneville range – spoke wheels, double rear shock absorbers, a long single‑piece seat, rounded fenders and a circular analogue instrument panel – while being equipped with a 398 cc TR engine delivering up to 42 hp, 37.5 Nm of torque, ABS and LED lighting. Local source Rush Lane noted the distinctive analogue dash, and Triumph officials suggest later versions may also offer a TFT screen.
