Something big is about to happen in India’s mid-size motorcycle segment, and the internet is not ready for it. Performance numbers for Triumph’s entire 350cc lineup have leaked ahead of the official April 6, 2026 launch — and the figures make Royal Enfield‘s segment dominance look suddenly very fragile.
I’ve been watching this story develop over the past few weeks, and now that the actual power, torque, and top speed numbers are out in the open, it’s time to break down exactly what Triumph has built — and whether these 350cc downgrades actually matter in the real world.
Why Triumph Is Going 350cc in the First Place
This isn’t a random engineering decision. Triumph has moved fast to align with India’s GST structure, which makes sub-400cc bikes fall into a more favourable tax bracket. By developing 350cc variants of their existing 400cc range — the T4, Speed, Scrambler 400X, and Thruxton — Triumph hopes to either lower prices or improve margins, or ideally both.
Right now, Triumph’s 400cc range sits at number 5 on India’s bestselling 350-450cc motorcycle list. These 350cc versions, launching April 6, are clearly aimed at climbing that chart. The strategy is smart, but whether buyers actually see a price benefit at the showroom remains to be seen — I’ll come back to that.
T4 350cc — The Entry Point Gets Leaner
The Triumph T4 is the most accessible model in the range, and the 350cc version reflects that positioning. Output drops from 31 PS and 36 Nm to 29 PS and 31 Nm — a small but measurable reduction. Top speed comes in at 137 km/h, down just 4.4 km/h from the 400cc version’s 141.4 km/h.
The 0-100 km/h time stretches slightly from 8.9 seconds to 9.6 seconds. On paper that sounds significant, but in traffic — on an Indian city road — you’re never going to feel that 0.7-second difference. What matters is that the T4 350 still crushes the Royal Enfield Classic 350, which manages only 20.2 PS and 27 Nm with a 5-speed gearbox. There is simply no comparison in terms of performance.
Speed 350cc — The One That Barely Changes
This is the result that genuinely surprised me. The Triumph Speed 350 produces 37 PS and 32 Nm, compared to the 400cc version’s 40 PS and 37.5 Nm. That’s a 3 PS and 5.5 Nm reduction — but the top speed barely moves, dropping from 148.7 km/h to 147 km/h.
The 0-100 km/h time goes from 7.4 to 8.1 seconds. That’s still seriously quick for a single-cylinder machine in this price range. If the Speed 350 ends up close to the Speed 400’s current pricing, Triumph has a genuine problem on its hands — in the best possible way.
Scrambler 350 — Adventure Spec Holds Strong
The Scrambler 400X is already a favourite in the adventure-lite segment, and the 350cc variant doesn’t disappoint. It shares identical power figures with the Speed 350 — 37 PS and 32 Nm. Top speed is rated at 144 km/h, just 2.5 km/h less than the 400cc version’s 146.5 km/h.
The 0-100 km/h time moves from 7.4 to 8.8 seconds. For a bike designed to handle both city commutes and weekend dirt trails, that performance envelope is more than adequate. Anyone considering an RE Himalayan should genuinely look at this number before writing a cheque.
Thruxton 350 — Most Powerful 350cc Single In India
This is the headline grabber. The Triumph Thruxton 350 makes 40 PS and 32 Nm of torque — and Triumph is positioning it as the most powerful single-cylinder 350cc motorcycle in the segment. Full stop. Top speed is a staggering 157 km/h, down from 161 km/h on the 400cc version.
The 0-100 km/h time comes in at 8.3 seconds. With a café racer design and that performance output, the Thruxton 350 is genuinely in a class of its own below 500cc. If you’ve been waiting for a premium café racer that doesn’t require emptying your entire bank account, April 6 is a date worth circling.

Will The Price Actually Drop?
Here’s the honest truth — and it’s a bit sobering. The whole point of developing 350cc engines was to benefit from the GST regime. But Bajaj already absorbed a GST hit without passing the savings to customers when rates changed. There’s a real chance Triumph plays the same game — keeping prices steady while quietly improving margins.
That said, Triumph is also expanding the range with new models like the Tracker 400 and Bonneville 400 in 2026. If the 350cc bikes are meant to anchor the lower end of the lineup while new 400cc models take the premium spots, it could actually work in the buyer’s favour. We’ll know for certain on April 6.
If you’ve been on the fence about upgrading from a Royal Enfield or are finally ready to step into the Triumph world, now is the time to visit your nearest Triumph dealership, take a test ride, and make sure you’re on the waiting list before the launch day rush begins. These numbers don’t lie — and neither does the demand that’s about to follow.
