Triumph Motorcycles has expanded its modern-classic lineup in India with two new entry-level Bonneville models. The Bonneville T40 and the more affordable Bonneville T4 share the same platform and mechanical package, but they differ in features, electronics, and styling. If you are deciding between the two, this detailed comparison will help you understand what you get for the extra money.
Shared platform and mechanicals
Both motorcycles are built around the same hybrid spine and perimeter frame made from tubular steel. The front suspension uses 43 mm conventional forks with 130 mm travel, while the rear gets twin shock absorbers with twin-tube hydraulic damping and seven-step preload adjustment, also offering 130 mm travel. Seat height is identical at 790 mm, and kerb weight is the same at 195 kg. Ground clearance stands at 165 mm, and the wheelbase measures 1,418 mm.
The heart of both bikes is the new 350 cc TR-series liquid-cooled single-cylinder engine. It produces 28.6 bhp at 7,000 rpm and 31.2 Nm of peak torque at 5,500 rpm. Triumph has revised the cylinder head and developed a dedicated state of tune for the Bonneville, focusing on strong low- and mid-range performance. Power goes to the rear wheel through a six-speed gearbox with an assist and slipper clutch. All-LED lighting is standard on both models.
Electronics and riding modes
This is where the main differences appear. The Bonneville T40 comes with five riding modes: Road, Rain, Eco, and two fully customisable settings. The T4 offers three modes: Road, Rain, and Eco.
The T40 gets cornering ABS, which adjusts braking force based on lean angle, along with cornering traction control that prevents rear-wheel slip on slippery surfaces. It also includes electronic cruise control, a feature absent on the T4. The instrument cluster on the T40 is a four-inch circular full-colour TFT display that supports smartphone connectivity for calls, music control, and turn-by-turn navigation via the Triumph app. It also offers a Heritage Mode that mimics classic analogue dials.
The T4 uses a conventional colour LCD display. It does provide turn-by-turn navigation, but it lacks lean-sensitive ABS, traction control, and cruise control. The ABS on the T4 is a standard dual-channel unit without cornering capability.
Colours and pricing
The Bonneville T4 is the most affordable Bonneville in the lineup, priced at Rs 2,54,999 ex-showroom. It comes in three solid colours: Black, Competition Green, and Carnival Red.
The Bonneville T40 is priced at Rs 2,79,999 ex-showroom. It is offered in four dual-tone colour schemes: Aegean Blue and Fusion White, Meriden Blue and Tangerine, Fusion White and Phantom Black, and Matt Pewter Grey with Fusion White. There is also a Bonneville T40 Black variant at the same price, featuring blacked-out engine casings, black wheel rims, and a choice of Matt Pewter Grey or Matt Phantom Black paint.
Which one should you choose?
If your budget is tight and you want the classic Bonneville look with the same engine, chassis, and ride quality, the T4 makes a strong case. You still get dual-channel ABS, three riding modes, all-LED lighting, and turn-by-turn navigation. You miss out on cornering ABS, traction control, cruise control, and the TFT display with smartphone connectivity.
The T40 justifies its Rs 25,000 premium with a significant feature upgrade. Cornering ABS and traction control add a layer of safety, especially in wet or cornering situations. Cruise control is a real benefit on highway rides. The TFT display with smartphone connectivity and Heritage Mode enhances the ownership experience. The dual-tone paint schemes also give the T40 a more premium, custom look.
For riders who value modern rider aids and a richer instrument cluster, the T40 is the better pick. For those who want the pure Bonneville experience at the lowest possible price, the T4 delivers the core package without the electronic extras.
