Triumph Bonneville T4 Launched in India at ₹2.54 Lakh: Is It the Bonneville to Buy?

The Triumph Bonneville T4 is the cheapest Bonneville you can buy in India, launched on 6 October 2026 at ₹2,54,999 (ex-showroom, Delhi). Until now, the badge meant spending around ₹10 lakh on the road for a T100. The T4 also undercuts the Bonneville T40 launched alongside it by ₹25,000, and online bookings opened on 7 October at 4:30pm.

Triumph Bonneville T4 on-road price in Delhi and monthly EMI

The ex-showroom figure is only part of the cheque. Add registration, insurance and handling charges, and the on-road price in Delhi should land near ₹2.9 lakh (expected, since early Mumbai and Pune listings sit around ₹2.95 lakh). A 20 per cent down payment is about ₹58,000. The remaining ₹2.32 lakh over 60 months at 11 per cent works out to an EMI of roughly ₹5,040.

Fuel is the second line item. Triumph hasn't published a certified mileage figure, but a 350cc single in this tune should return around 30-33 kmpl in mixed Indian riding (likely, not confirmed). At 1,000 km a month and petrol near ₹103 a litre, that is about 31 litres, or ₹3,200. EMI plus fuel comes to roughly ₹8,200 a month. Budget another ₹5,000-6,000 for the 10,000 km service, which is an estimate until dealers publish labour rates.

What the 350cc engine gives you

The T4 uses Triumph's liquid-cooled TR Series single, the same family as the T40, but tuned specifically for the Bonneville. It gets a revised cylinder head, dedicated camshafts and smaller throttle bodies. Output is 29 PS (about 28.6 bhp) at 7,000 rpm and 31 Nm at 5,500 rpm, sent through a six-speed gearbox.

Those numbers look modest next to the 398cc Speed 400's 40 PS and 37.5 Nm, which Drivio has covered. The gap is deliberate. At 350cc the bike falls into GST's 18 per cent slab, while anything larger is taxed at 40 per cent. That is a big part of how Triumph reaches ₹2.55 lakh.

The tune favours pull from low revs over top-end rush. In Delhi's stop-start crawl, that matters more than a spec-sheet race. The T40 gets taller overall gearing, so the T4 will likely feel busier around 100 km/h on the highway.

Bonneville T4 vs T40: what ₹25,000 buys

The T4 is not a stripped bike. It keeps full-LED lighting with a daytime running light, dual-channel ABS, traction control and Emergency Deceleration Warning. The colour LCD shows turn-by-turn navigation, and Bluetooth lets you handle calls and contacts from the handlebar switchgear. Colours are Phantom Black, Carnival Red and Competition Green.

What you give up is the round TFT with its Heritage Mode, three of the T40's five ride modes, cruise control and lean-sensitive rider aids. The T4 makes do with Road, Rain and Eco, which change throttle response, traction control and ABS settings.

Cruise control is the one feature I would pay for. On a long run like Delhi to Jaipur, it saves your wrist. In city traffic you will never miss it. The delivery gap matters just as much. The T40 reaches owners about two months earlier.

Where the T4 sits among its rivals

The obvious target is the Royal Enfield Classic 350, which runs roughly ₹1.8-2.2 lakh ex-showroom depending on variant (likely, so check current prices). The Triumph Bonneville T4 therefore asks for a premium somewhere between ₹35,000 and ₹75,000. Honda's CB350 sits in the same bracket. Buyers who want more displacement should also cross-check the Royal Enfield Guerrilla 450 that Drivio covered earlier.

The extra money buys liquid cooling, a six-speed box, traction control and a badge that carries real weight. It also buys a thinner service network. Triumph has a fraction of Royal Enfield's workshops, so find your nearest one before you book.

Buy the T4 or pay for the T40?

Take the T4 if your riding is mostly city commuting with the odd weekend run, and you can wait until January. The ₹25,000 saved covers a good riding jacket and a helmet. Take the T40 if you ride highways often, want cruise control, or don't want to wait the extra two months. Choose the Classic 350 over either if service access matters more than the Bonneville name.
