The much-awaited Triumph Bonneville 400 is once again seen on the road, but without a disguise this time, giving quite a few details about the model. It is said to be one of the most direct competitors of the Royal Enfield Classic 350 since the brand ventured into the entry-level middleweight space in collaboration with Bajaj Auto. Notably, the leaks suggest that it will have more of a retro aesthetic. Here are all the details.
Triumph Bonneville 400 Launch Date and Price in India
The Triumph Bonneville 400 has been spotted in India undisguised, signaling that the launch is near. Although an official launch date has not been unveiled yet, experts anticipate it to happen by June 2026 or by the Q4 2026 festive season.
Notably, Triumph is shifting its strategy in India. It is downsizing its 400cc platform to a 350cc guise to benefit from lower taxation (under 350cc) and compete more aggressively on price. Speaking of which, the price of this upcoming model is expected to be ₹1.85 lakh to ₹2.10 lakh (ex-showroom).

Leaked Designs and Features of Triumph Bonneville 400
Bikewale reports that the bike will likely stay true to the Bonneville lineage, with the retro design. Here are the details on the design and features: –
Design
According to reports, it will feature a round LED headlamp, a teardrop-shaped tank, long, chunky mudguards, and the signature peashooter exhaust.
The traditional hardware is also spotted, including its gaitered telescopic fork and twin rear-shock absorbers, which are seen in the larger-capacity Bonneville models. However, that is not all because the bike also has some modern touches with a single-pod digital instrument console.
Interestingly, the console has quite a few rider-supporting features, including smartphone connectivity for turn-by-turn navigation.
Engine
As mentioned above, Triumph is attempting to downsize its 400cc lineup to under 350cc for tax benefits and dominate in the sub-350cc category. For the same purpose, they had recently launched the Tracker 400 and the entire 400 lineup in India, now in a 350cc guise.

However, the competition is challenging this time with the Bonneville 400 rumored to have nearly double the power and liquid cooling at a price point of the Royal Enfield’s mid-to-top variants.
| Factor | Royal Enfield Classic 350 | Triumph Bonneville 400 (Expected) |
|---|---|---|
| Power | 20.2 BHP (Relaxed, low-end thump) | ~35 BHP (Punchy, highway capable) |
| Cooling | Air-Oil Cooled | Liquid Cooled |
| Transmission | 5-speed | 6-speed |
| Weight | ~195 kg (Heavier, planted feel) | ~175–180 kg (Expected to be nimbler) |

| Philosophy | “Pure Motorcycling” & Heritage | Premium Performance & Refinement |
Who Wins?
Since the Triumph Bonneville 400 is still far from launch, it is hard to declare a winner. However, from the leaks and expected specifications, experts have made a rough conclusion, stating Classic remains superior for the one looking for thump and heavy metal feel, whereas the one looking for a 1960s icon with an effortless cruise at 120 km/h, Bonneville 400 may turn out to be perfect.
