At the heart of the Speed T4 is the same 398cc engine found in the Speed 400, though in a slightly detuned state. Producing 30.6 bhp at 7,000 rpm and 36 Nm at 5,000 rpm, it prioritizes low-end torque and tractability over outright power. That makes it ideal for daily commuting and casual weekend rides. 

The motor is refined and surprisingly smooth under 100 kmph, with a soft, linear throttle response that won’t intimidate newer riders. It cruises happily between 80-90 kmph but starts to feel strained closer to 120 kmph. Vibrations become noticeable after 100 kmph, especially through the pegs and handlebars. Still, fuel efficiency is a strong point, returning between 30-34 kmpl depending on how and where you ride. With a 13-litre fuel tank, you’re looking at a real-world range of 390 to 442 km—great for a mix of city and light touring duties.

The Triumph Speed T4 sticks to the tried-and-true retro roadster aesthetic, and while it’s clearly based on the Speed 400, it carves its own identity as a more budget-focused offering. The 13-litre sculpted fuel tank, round LED headlamp, and old-school styling cues like the twin-pod instrument cluster (with a semi-digital LCD) give it a classic feel, while details like machined engine fins and minimal bodywork add a modern touch.

 The finish isn’t quite as rich as the Speed 400—plastic panels and basic mirrors do hint at cost-saving—but overall it still looks well put together. It comes in three shades: Metallic White, Phantom Black, and Sapphire Black. While it doesn’t feel as premium as some of its pricier siblings, the styling is distinctly Triumph and retains a mature, no-nonsense appeal that many riders will appreciate.

With a price tag ranging from ₹1.99 to ₹2.24 lakh (ex-showroom), the Triumph Speed T4 is positioned below the Speed 400 (₹2.42 lakh), making it one of the most affordable Triumphs ever. Its key rivals include the Royal Enfield Hunter 350, Honda CB350, and Bajaj Dominar 400. The Hunter 350 is lighter on the wallet and has a strong community following, but it feels underpowered and less refined. 

The CB350 matches the T4 in price and refinement but lacks Triumph’s badge value and equipment like traction control. The Bajaj Dominar 400, meanwhile, offers more power and better highway performance (39.5 bhp) but feels bulkier and less nimble in the city. What the Speed T4 brings to the table is a strong brand presence, elegant design, and an engine that’s easy to live with—making it a top choice for newer riders or those stepping up from a commuter motorcycle.

The Triumph Speed T4 makes a convincing case as an everyday retro motorcycle that doesn’t cost a fortune to own or run. It brings the Triumph brand within reach of a wider audience, offering stylish looks, practical performance, and key features like dual-channel ABS and traction control. 

While it sacrifices a bit of performance and flash compared to the Speed 400, it still delivers where it matters—comfort, usability, and real-world efficiency. For someone looking for a stylish, no-fuss daily bike with some weekend charm, the Speed T4 fits the bill. Enthusiasts might miss the bite and power of bigger bikes, but for what it is, the T4 is a smart and sensible choice.
