The date of October 6, 2026 will forever be etched in the history of Triumph Motorcycles as the day they declared WAR against Royal Enfield.
The British bike manufacturer is set to unveil a retro-classico, the Bonneville 400 globally, which is poised to disrupt the status quo of the 350cc segment. However, the details, images, and insider information obtained by us already demonstrate that this is not another motorcycle but rather a precisely engineered missile aimed directly at the heart of India’s bestselling motorcycle, the Royal Enfield Classic 350. And the specs of this motorcycle will surprise you!
Engine: 349cc or 398cc? The SHOCKING truth
Triumph has been playing a game of cat and mouse with the engine capacities. The global launch for Triumph Bonneville 400 was supposed to have 398cc liquid-cooled single-cylinder engine that delivers 40 PS and 37.5 Nm of torque, which powers the Speed 400. However, the taxation structure under GST in India dictated otherwise, and Triumph is said to have downsized the engine capacity from 398cc to 349cc.
Expected India specifications:
Engine: 349cc liquid-cooled single-cylinder 6 speed.
Power: ~29-36 PS (torque-focused)
Torque: ~31-32 Nm.
Top speed: 140 km/h (estimated)
However, even though the Bonnie 349cc is liquid-cooled, Royal Enfield’s Classic 350 and Honda’s CB350 are both air-cooled engines. In the toasty summer season in India, stuck in traffic jams, and with the AC on, you will see the need for liquid-cooled engines. The 350cc segment is all about the air-cooling capacity, but the Triumph Bonneville 400 with its liquid-cooling technology can run longer miles with the same power output as its competitors without power loss.
Design: The REAL Bonneville DNA
Triumph did not just throw a “Bonneville” label on the Speed 400 and call it a day. The images of the motorcycle obtained by us showcase a different story as to how different the Triumph Bonneville 400 is from the rest of Triumph’s 400cc motorcycles.
Key design features:
Telescopic forks with gaiters: The USD forks that we see on the Speed 400 are nowhere to be found on the Triumph Bonneville 400. Rather Triumph has equipped it with telescopic forks with chrome gaiters, much like its big brother T120.
Twin rear shocks: Gone are the days of having a monoshock on the rear, as the Bonneville 400 has been fitted with twin rear shocks, which not only adds to a sense of vintage-ness but also improves the performance.
Teardrop fuel tank: A bigger teardrop-shaped fuel tank with knee-recesses to give it a more authentic feel than what the Street 675 had.
Flat bench seat: A long flat bench seat with a chrome grab rail on the rear for the pillion.
Peashooter exhaust: The iconic chrome peashooter exhaust for the purists out there.
Wire-spoked wheels: Wire-spoke wheels (18-inch front and 17-inch rear) complete the vintage appeal.
Technology: Retro look, MODERN brains
Do not be deceived by the design, inside the Triumph Bonneville 400 is a tech-packed marvel that the Royal Enfield Classic 350 can only dream of.

Expected features:
LEDs everywhere: Headlamp, indicators, and tail lamp are all expected to be LEDs.
TFT dashboard: A TFT circular dashboard (much like the Speed 400) with Bluetooth connectivity that will notify the rider of incoming calls, SMS, and navigation information.
Ride-by-wire throttle: For enhanced control and better performance.
Dual-channel ABS: As standard across all variants.
Slipper clutch: For better downshifting and reduction of rearend torque reaction.
USB port: To satisfy the modern rider who wishes to charge their devices on the go.
Pricing: The ₹2.5 Lakh bomb
It is the most awaited segment to know the price for, and the Speed 400 at ₹2.17 Lakh ex-showroom is the closest to the expected price of Triumph Bonneville 400. The Scrambler 400 costs around ₹2.29 Lakh, whereas the Triumph Bonneville 400 with its twin rear shocks and premium look will be priced anywhere between ₹2.40 and ₹2.60.
Compared to its competitors:
Royal Enfield Classic 350: ₹1.90 Lakh – ₹2.20 Lakh
Honda CB350: ₹2.05 Lakh – ₹2.30 Lakh
Triumph Bonneville 400: ₹2.40 Lakh – ₹2.60 Lakh (expected)
It can be argued that the price of Triumph Bonneville 400 speaks volumes about its position in the market segment. However, for an extra ₹30,000-40,000, one can get more comfort, convenience, performance, and technology with the Triumph Bonneville 400.
The Verdict: Will it dethrone the King?
The King of the 350cc segment, Royal Enfield, may soon be ousted by the Triumph Bonneville 400, which has come to deliver the classic look that the potential Royal Enfield customers are looking for, but with a touch of modernity that the Royal Enfield Classic 350 lacks. So, when should you purchase the Royal Enfield Classic 350 and when should you buy the Triumph Bonneville 400? Here’s our buying guide below:
Buy the Bonneville 400 if:
You want a proper classic motorcycle with modern technology
You are riding on a hot climate and require liquid-cooling technology
You want to own a Triumph motorcycle with its premium feel
You are interested in a 6-speed transmission for touring
Stick to the Classic 350 if:
You are on a budget
You want to ride an air-cooled single-cylinder engine
You want the most extensive service network in India
On October 6, Triumph is set to unveil the Bonneville 400 and the 350cc segment will never be the same again. This is not just another motorcycle but a game-changer that will deliver a message straight to Royal Enfield, telling them “Your reign ends here.” And whether this will actually happen or not boils down to one factor – the price. As long as Triumph can keep the price under ₹2.5 Lakh, the Triumph Bonneville 400 will see the best-selling classic motorcycles in India by 2027. The wait is almost over, and the Bonnie is on its way with which Royal Enfield should be really worried.
