Triumph‘s 350cc range is specifically developed for India, complying with the latest GST 2.0 norms. There are three different (road-biased) bikes built off the same base. The Triumph Speed 400 is the standard roadster, the Triumph Speed T4 is the more wallet-friendly way in, and the Triumph Thruxton 400 is the sportier cafe racer of the bunch. Here’s how they actually stack up against each other.

All three run the same 349cc, liquid-cooled single, but Triumph hasn’t tuned them the same way. The Thruxton gets the most power of the lot, which tracks given it’s meant to be the sportiest of the three. The Speed T4 is the most mellow one, since its whole job is being the cheapest way into a Triumph. The Speed 400 sits comfortably in between, and if you ask us, that middle ground is probably where most riders will feel most at home. All three share the same 6-speed box and slip-and-assist clutch, so you can expect the same light lever feel and smooth downshifts.

All three have the same tubular steel frame, and Triumph hasn’t skimped on braking either; every single one gets dual-channel ABS with a 300mm front disc and a 230mm rear disc. The real difference is up front. The Speed 400 and Thruxton get the more advanced and nicer-looking upside-down forks, while the T4 makes do with a conventional telescopic setup. The regular fork on the T4 helps keep the costs in check. Also, the Speed T4 rolls on affordable MRF Nylogrip Zapper tyres, whereas the Speed 400 gets the more premium Vredestein Centauro ST rubber. The Thruxton rides on MRF Steel brace tyres for better cornering capability.

All three carry the same 13-litre tank, so you shouldn’t see any major difference in range between them. The Thruxton has the lowest seat of the three at 795mm, which fits its more forward-leaning, cafe racer stance. The T4, meanwhile, gets the most ground clearance, handy if your daily route isn’t smooth. Weight-wise, there’s really nothing to worry about here; the Thruxton is the heaviest, but only by a few kilos over the Speed 400.

Every bike here gets the same semi-digital console, an analogue speedometer paired with a digital inset that handles the tachometer, gear position, and trip meters. None of them offer Bluetooth or riding modes, so if you were hoping for a colour TFT with phone pairing, you’re looking at the wrong Triumphs. But then again, having a simple console goes well with the neo-retro character of the bikes. That said, Triumph should’ve kept the engine immobiliser intact as the 400cc counterparts had them.

The Speed T4 is honestly the cheapest way into this lineup, though you do miss out on some power and the fancier suspension hardware. That said, it still has the value-for-money quotient and is great for buyers on a budget.

The Speed 400 makes the most sense if you want a well-rounded roadster without stretching too far. The Thruxton costs the most and is ideal only for those who are keen on buying a cafe racer-style motorcycle. The sportier riding posture may not be ideal for daily commutes. But if performance and looking cool are your priorities, then go for it. Otherwise, the Speed 400 is the most balanced option.
