Triumph Motorcycles Nepal is set to expand its 400cc range in Nepal with the new Bonneville 400, with the motorcycle expected to arrive in the country by early 2027. The new model brings Triumph’s most recognisable classic motorcycle name into its 400cc platform.
The Bonneville T40, T40 Black and Bonneville T4 have now been introduced in India, adding a more traditional roadster to Triumph’s growing 400cc family. In Nepal, the Bonneville 400 is expected to sit alongside the Speed T4, Speed 400, Scrambler 400X and Scrambler 400 XC.
In India, the T40 and T40 Black are priced at INR 2.80 lakh, while the T4 is priced at INR 2.55 lakh, ex-showroom Delhi. Deliveries of the T40 and T40 Black are scheduled to begin from mid-November 2026, with the T4 following from January 2027.

Unlike the Speed 400 and Scrambler models, the Bonneville 400 leans heavily into classic motorcycle styling. The design features a rounded headlamp, teardrop-shaped fuel tank, long mudguards, wire-spoke wheels, twin rear shocks and a peashooter-style exhaust.

The attention to detail also extends to the finishes. The T40 gets heritage-inspired two-tone paint options, with hand-painted coach lines, rubber tank pads and the traditional Triumph tank badge adding to its retro character.
The T40 Black takes the same basic design in a darker direction, with Matt Pewter Grey and Matt Phantom Black finishes and blacked-out engine and exhaust components.

Underneath the classic styling is Triumph’s familiar 400cc TR Series single-cylinder engine. For the Bonneville, the engine gets its own calibration and a revised cylinder head, with Triumph focusing on a smoother, more relaxed delivery rather than outright performance. The T40 produces 32 PS and 36 Nm, with peak torque arriving at 5,000rpm.

The motorcycles also bring considerably more technology than their appearance might suggest. The T40 and T40 Black get a 4-inch circular TFT display, which can be switched to a Heritage Mode for a more traditional-looking interface. Smartphone connectivity, full-map navigation, music and phone functions are also integrated into the system.
There are three standard riding modes — Road, Rain and Eco — along with two configurable modes. Cruise control is also available, while lean-sensitive cornering ABS and traction control bring electronic rider assistance that would have been unusual on a traditionally styled motorcycle of this size a few years ago.

The more affordable Bonneville T4 takes a simpler approach. It gets a colour LCD display rather than the T40’s TFT unit and uses turn-by-turn navigation instead of full-map navigation. It also misses out on some of the T40’s additional electronic features, while retaining the core Bonneville styling and three riding modes.
The chassis remains deliberately traditional. The motorcycles use conventional front forks, twin rear shock absorbers and 18-inch front and 17-inch rear spoke wheels with aluminium rims. The setup is a clear departure from the upside-down forks and monoshock arrangements increasingly common in modern 400cc motorcycles.

With a 790mm seat height, the Bonneville 400 should also be relatively accessible for a wide range of riders. An optional low seat can bring the height down to 770mm. Triumph lists the ready-to-ride weight at around 195kg, while a centre stand comes as standard.
For Nepal, the Bonneville 400 could fill an interesting gap in Triumph’s current line-up. The Speed 400 offers a more contemporary roadster character, while the Scrambler 400 X and XC cater to riders looking for a more rugged design and additional versatility.
The Bonneville, meanwhile, is aimed at buyers who want the classic motorcycle experience without moving into the larger and more expensive Bonneville family. Once introduced, it will become the fifth member of Triumph’s 400cc family in Nepal, giving the brand a broader choice across the segment.
