Triumph Bonneville T40 vs Royal Enfield Bullet 350: Which One For Whom?

The 350cc retro space in India just got a new addition, a beautiful one at that. Triumph has introduced its new Bonneville T40 range, making the legendary Bonneville far more accessible. Alongside sits the Royal Enfield Bullet 350, a simple roadster that sticks to an old-school approach. While both share a timeless aesthetic, they cater to ‘same-same-but-different’ kinds of riders. Confused? We explain, and also help you figure out which one you should go for:

Price

The entry-level Bonneville T4 costs approx Rs 91,000 more than the base Bullet 350. Yes, that is a lot of money, but Triumph genuinely tries to justify this with a whole load of differences. So, it really comes down to whether you prefer straightforward classic simplicity or a no-compromise retro bike with modern features.

Design & Build Quality

The Triumph Bonneville T40 takes inspiration from the 1960s Bonneville. It gets a teardrop fuel tank with rubber knee pads, peashooter exhausts, and twin rear shock absorbers. The engine gets machined fins to mimic an air-cooled motor. The attention to detail is exceptional, from the neat cable routing to the high-grade paint finishes; it surprisingly looks very similar to the larger Bonneville T100 that too, at a lower price point.

The Royal Enfield Bullet 350 is loyal to its heritage. It features a round halogen headlamp, wire-spoke wheels, fat, full-length steel fenders, and a classic single-piece seat with a gently scooped section for the rider. On the higher variants, you get the hand-painted pinstripes on the fuel tank. 

If you prefer an uncomplicated, raw, heavy-metal feel with deep heritage roots, the Bullet delivers just that. If you want an elegant, finely detailed machine that masks its modern inner workings well with authentic Bonnie looks, the Bonneville will appeal to you.

Engine & Performance

The Bullet 350 is retro through and through. It’s got the torquey thump (although a bit muted thanks to emission norms), a very relaxed nature thanks to its air-cooled, long-stroke construction. It’s best enjoyed in a chilled-out manner, and can feel relaxed when you’re cruising at around 80-90kmph on the highway, enjoying the sights. 

The Bonneville T40 has a liquid-cooled 350 cc engine, so obviously, this one’s much more advanced than the air-cooled Bullet’s heart. Consequently, it will also be the sportier one of the lot, so it’s for those who want a retro-styled bike but don’t want to compromise on performance. Both weigh the same, but the Bonnie’s lower seat should make it friendlier for shorter riders. 

Features & Technology

Royal Enfield keeps electronics on the Bullet 350 straight to the essentials. You get an analogue speedometer paired with a small LCD read-out for fuel levels, trip meters, and an odometer, along with a USB charging port. It skips complex menus, so there is nothing to distract from the simple joy of riding. For those who still want navigation assistance on long runs, Royal Enfield offers a Tripper pod as a genuine accessory without cluttering the stock dash.

The Bonneville T40 blends classic aesthetics with current technology. Standard equipment includes full LED lighting with a signature DRL, ride-by-wire throttle, multiple riding modes (Road, Rain, Eco), traction control, and dual-channel ABS. The T40 and T40 Black trims feature a 4-inch round TFT console with a Heritage display mode (which has Specificationsgraphics emulating an analogue tachometer), Bluetooth pairing, call/SMS alerts, and full Google Maps mirroring navigation support. Even the base T4 variant comes with turn-by-turn navigation on its digital display as standard.

Feature-wise the Bullet is for those who don’t like distractions, whereas the Bonnie will appeal to those who like to stay connected on-the-go.

BikeDekho Says

All in all, the Triumph Bonneville T40 is for someone who likes the retro look but still wants all the modern conveniences. You might feel that this is a little pretentious, but Triumph has made sure the careful attention-to-detail makes the Bonnie a proper, genuine retro bike. The brand has incorporated all sorts of modern tech so that if you’re using the bike for a highway group ride with your friends with sportier machines, it won’t shy away from being able to keep up. The only caveat is that you’ll have to wait a little bit to get your hands on one as the deliveries are scheduled to commence in the second week of November 2026.

On the other hand, the Bullet is for those who often like to use the phrase “Embrace Tradition, Reject Modernity”. It knows what it is and doesn’t pretend or doesn’t even compromise to be anything otherwise. It’s an old-school machine with just about enough modernity that allows the rider to live with it better (read refinement). It’s the kind of motorcycle that’ll appeal to those who appreciate the calmness that motorcycling brings about. This experience is also a whole lot less expensive, so that’s a bonus depending on your perspective.
