Triumph Bonneville 400- If you’re a fan of classic British motorcycles but don’t want to spend big on a full-size Bonneville T120, 2026 could be your year. Fresh spy shots have surfaced showing what looks like Triumph’s long-rumored Triumph Bonneville 400 – a “baby Bonnie” that blends timeless heritage styling with the proven performance of the 400cc platform.
Motorcycle News and other outlets reported the latest images just days ago (early April 2026), and the internet is buzzing. This new retro roadster could finally give Royal Enfield Classic 350 and Jawa riders some serious premium competition. Here’s everything we know so far about the Triumph Bonneville 400.
Triumph’s partnership with Bajaj has already delivered hits like the Speed 400, Scrambler 400 X, Thruxton 400, and Tracker 400. These bikes proved that a lightweight, characterful single-cylinder can deliver real fun without the premium price tag of the bigger Bonnevilles.
The Bonneville 400 takes things further by going full retro. Spy shots reveal a teardrop-style metal fuel tank, classic round LED headlight, rubber fork gaiters, long flat bench seat, and twin rear shocks – exactly the DNA that made the original Bonneville an icon. It looks more “pure Bonnie” than the Speed 400’s sportier stance.

Bonneville 400 Performance
Power should come from the familiar liquid-cooled 398cc TR-Series DOHC single-cylinder engine (some early rumors hint at a possible new 350cc tune for even better efficiency). Expect around 39–41 hp and strong low-end torque – perfect for city commuting and weekend blasts.
Other likely features:
- 6-speed gearbox with slipper clutch
- Dual-channel ABS
- USD front forks
- Spoked wheels with tubeless tyres
- Digital instrument cluster with modern connectivity
- Premium fit-and-finish that feels more expensive than the price suggests
Triumph Bonneville 400 Price
In India (the biggest expected market), the Triumph Bonneville 400 price is tipped between ₹2.00 lakh and ₹2.25 lakh (ex-showroom). That positions it perfectly between entry-level retros and premium classics
The Triumph Bonneville 400 feels like the missing piece in Triumph’s Modern Classics lineup. It takes everything great about the Speed 400 platform and wraps it in pure 1960s-inspired styling that will turn heads everywhere.
Whether you’re a first-time buyer stepping up from a 350cc or a seasoned rider downsizing without losing character, this bike looks set to deliver. Keep an eye on Triumph showrooms later this year – the Bonneville 400 could be the retro motorcycle story of 2026.
