Upcoming Triumph Bonneville 350 Spotted Testing Again
With its retro styling, it does look like a proper Triumph Bonneville
Quick Highlights:
-
Spotted testing in India once again
-
Design remains largely unchanged from the previous test bike
-
India launch expected by September 2026
The upcoming Triumph Bonneville 350 has been spotted testing in India once again, and this latest prototype looks almost identical to the one seen previously. That suggests Triumph has largely finalized the motorcycle’s design, with the brand now likely focusing on final validation before its expected launch in September, 2026. Just like before, the bike carries a proper retro roadster design inspired by Triumph’s iconic Bonneville family. The overall silhouette, and styling are reminiscent of the larger Bonneville T100, giving the small-capacity motorcycle an authentic classic appeal instead of a retro-inspired modern design.
The test mule continues to feature a teardrop-shaped fuel tank with an offset fuel filler cap, a round LED headlight, circular indicators, a neatly sculpted single-piece seat and wired-spoke wheels. The test mule was seen with all-black engine covers, handlebar, rear grab rail and the signature peashooter-style exhaust adding to the premium old-school look. The underpinnings also appear to be unchanged. The motorcycle uses a conventional telescopic fork with fork gaiters and twin rear shock absorbers, staying true to the classic Bonneville formula. The spoke wheels are expected to come with tube-type tyres, which would further reinforce its retro character.
One detail that continues to grab attention is the instrument console. The console is not properly visible, but it is expected to feature a TFT display, different from the one seen on Triumph’s existing 350cc bikes. Mechanically, the Bonneville 350 is expected to use the same downsized 350cc engine from the Triumph Speed T4.
BikeDekho Says
Since this test mule looks nearly identical to the previous one, it seems Triumph has locked in the final design. With its premium retro styling and expected price of around Rs 1.85 lakh (ex-showroom), the Bonneville 350 could become an attractive alternative to the Royal Enfield Classic 350, Bullet 350, Honda CB350 and Jawa 350.
