Triumph Bonneville 400 explained: expected price in India, engine specs, features, and how it compares to the Royal Enfield Classic 350. Updated 2026 guide.
Updated 2026
Triumph Bonneville 400 is an upcoming classic-styled motorcycle from Triumph Motorcycles, expected to share the 398cc liquid-cooled engine from the Speed 400 and launch in India around 2026. It is designed to compete directly with the Royal Enfield Classic 350 and Honda CB350 in the retro motorcycle segment.
The Triumph Bonneville 400 is one of the most anticipated motorcycles for the Indian market. Enthusiasts have been waiting for a true classic-styled Triumph at an accessible price point, and the Bonneville 400 appears to be exactly that. This guide covers everything we know so far, including expected specs, price, launch timeline, and how it stacks up against rivals.
Before we dive in, note that Triumph has not officially confirmed the Bonneville 400. The information below is based on trademark filings, spy shots, and the existing Speed 400 platform. We will update this guide as official details emerge.
The Triumph Bonneville 400 is an upcoming retro motorcycle from Triumph Motorcycles, positioned below the Bonneville T100 and above the Speed 400 in the company's lineup. It is expected to be built in India at the Bajaj-Triumph plant in Chakan, Pune, and exported to global markets.
The name Bonneville carries decades of heritage, and a 400cc version would make that heritage accessible to a wider audience. Spy shots have shown a motorcycle with a teardrop fuel tank, twin clocks, a round headlamp, and chrome exhaust, all classic Bonneville cues.
The Triumph Bonneville 400 is expected to use the same 398cc single-cylinder liquid-cooled engine as the Speed 400. This engine produces 40 PS at 8,000 rpm and 37.5 Nm at 6,500 rpm, and it is mated to a six-speed gearbox with a slip-and-assist clutch.
| Specification | Expected value | Source |
|---|---|---|
| Engine | 398cc, single-cylinder, liquid-cooled | Triumph Speed 400 official |
| Power | 40 PS at 8,000 rpm | Triumph Speed 400 official |
| Torque | 37.5 Nm at 6,500 rpm | Triumph Speed 400 official |
| Kerb weight | 170 kg (approx.) | Triumph Speed 400 official |
| Seat height | 790 mm | Triumph Speed 400 official |
These figures come from the Triumph Speed 400 official page. The Bonneville 400 may have slightly different tuning to suit its classic character, but the core engine is expected to remain unchanged.
In terms of ride quality, the Speed 400 platform is praised for its refined engine, good low-end torque, and stable handling. The Bonneville 400 should offer the same strengths with a more upright, relaxed riding position.
The Triumph Bonneville 400 price in India is expected to be between Rs 2.40 lakh and Rs 2.60 lakh (ex-showroom). This would place it slightly above the Speed 400, which currently retails at around Rs 2.33 lakh, and below the Bonneville T100, which costs over Rs 9 lakh.
Triumph has not announced an official launch date. However, spy shots and trademark filings suggest a launch in 2026. The motorcycle has been spotted testing in India multiple times, indicating that development is well advanced.
When it launches, the Bonneville 400 will be manufactured at the Bajaj-Triumph plant in Chakan, which already produces the Speed 400 and Scrambler 400 X. Local production will help keep costs competitive.
The Triumph Bonneville 400 will compete directly with the Royal Enfield Classic 350, offering more power and modern engineering in a similar retro package. Here is how the two compare on paper.
| Feature | Triumph Bonneville 400 (expected) | Royal Enfield Classic 350 |
|---|---|---|
| Engine | 398cc liquid-cooled | 349cc air-cooled |
| Power | 40 PS | 20.2 PS |
| Torque | 37.5 Nm | 27 Nm |
| Weight | 170 kg (approx.) | 195 kg |
| Price (ex-showroom) | Rs 2.40 to 2.60 lakh | Rs 1.93 to 2.25 lakh |
The Classic 350 figures are from the Royal Enfield Classic 350 official page. The Bonneville 400 has a clear power advantage, but the Classic 350 is cheaper and has a massive service network across India.

The Triumph Bonneville 400 features classic styling with a round headlamp, teardrop fuel tank, and wire-spoke wheels. Spy shots also show a single-piece seat, chrome exhaust, and twin analog clocks, all inspired by the original Bonneville models.
Expected features include full LED lighting, a digital-analog instrument cluster, dual-channel ABS, and a slip-and-assist clutch. The motorcycle is likely to be offered in classic color options such as British Racing Green, Jet Black, and a two-tone red and silver scheme.

If you prefer classic looks, wait for the Bonneville 400; if you want a modern roadster, the Speed 400 is available now. The two motorcycles share the same engine and frame, so the main differences are styling, ergonomics, and price.
The Speed 400 has a more aggressive stance with a slightly forward-leaning riding position. The Bonneville 400 is expected to offer a more upright, relaxed posture, making it better for long-distance cruising. Both are excellent motorcycles, so the decision comes down to personal taste.
As Triumph CEO Nick Bloor said at the Speed 400 launch, "The new Speed 400 is a genuine Triumph, with the style, presence and performance that our brand is known for." The same philosophy is expected to carry over to the Bonneville 400.
