The KTM 390 Duke and the Triumph Speed 400 sit in different segments on paper, but in the real world, they chase the same buyer. Both wear a 350cc class engine now, both carry premium badges, and both promise more character than a typical commuter. A gap of roughly Rs 50,000 separates them, yet that hasn't stopped potential customers from cross shopping the two. Here's how they stack up on price, powertrain, features and hardware.
Price Comparison
The Triumph Speed 400 starts at Rs 2.34 lakh, ex-showroom. The KTM 390 Duke starts at around Rs 2.84 lakh, ex-showroom. That works out to a difference of roughly Rs 50,000, with the KTM sitting at the higher end.
Both brands trimmed their engines down to the 350cc mark this year to slot into a friendlier 18% GST bracket, which brought both prices down from where they stood before. The Speed 400 still holds its position as the more affordable of the two, and it remains one of the most accessible ways into a Triumph.
They both come in a single variant and are offered in multiple colour options, which are:
Triumph Speed 400 | KTM 390 Duke |
|---|---|
Racing Red / Pearl Metallic White | Liquid Carbon |
Pearl Metallic White / Pewter Grey | Slate Grey |
Phantom Black / Pewter Grey | Atlantic Blue |
Racing Yellow / Pearl Metallic White | - |
Powertrain
The KTM 390 Duke runs a 349.32cc, single cylinder, liquid-cooled LC4c engine. It produces 41.5 PS and 33.5 Nm of torque, paired with a 6-speed gearbox. The engine leans into a free-revving, top-end character, which suits KTM's streetfighter positioning.
The Triumph Speed 400 runs a 349cc single cylinder, liquid-cooled TR series engine. It produces 37 PS and 32 Nm of torque, also through a 6-speed gearbox with a slip-assist clutch. Triumph has tuned it for a smoother, more tractable mid-range, which favours relaxed, everyday riding over outright thrills.
On paper, the KTM holds a small edge in outright power and torque. The Triumph counters with a smoother delivery that many riders find easier to live with in traffic. Ironically, neither bike has dropped the "400" from its name, even though both now run smaller, downsized engines. That's bound to confuse buyers who aren't tracking the GST driven changes closely. This comparison should clear that up.
Powertrain | KTM 390 Duke | Triumph Speed 400 |
|---|---|---|
Engine | 349.32cc | 349cc |
Power | 41.5 PS | 37 PS |
Torque | 33.5 Nm | 32 Nm |
Gearbox | 6-speed with slip and assist-clutch | 6-speed with slip-assist clutch |
Features and Electronics
This is where the two bikes pull furthest apart.
The 390 Duke comes loaded. It gets a 5-inch TFT colour display with Bluetooth connectivity, three riding modes (Street, Rain and Track), adjustable Motorcycle Traction Control, cornering ABS via an IMU, Supermoto ABS, launch control, cruise control, and a bidirectional quickshifter. It's a features list that would look at home on a bike costing far more.
The Speed 400 takes a simpler approach. It sticks with a semi-digital instrument console rather than a full TFT, and it skips Bluetooth connectivity, a quickshifter and cruise control. It does get switchable traction control and dual-channel ABS, which covers the essentials. Triumph has clearly prioritised build quality and finish over a long features list here.
Riders who want their motorcycle to double as a gadget will lean towards the KTM. Riders who prefer a simpler, more analogue experience may not miss what the Triumph leaves out.
Hardware and Chassis
The 390 Duke uses a trellis frame with upside-down front forks that you can adjust for preload, compression and rebound, plus a rear shock you can adjust for preload. It weighs around 165-168kg and carries a 15 litre fuel tank. This lighter build is why it changes direction so quickly on winding roads.
On the other hand, the Speed 400 uses upside-down front forks too, paired with a rear shock. It weighs around 179kg and carries a 13 litre fuel tank. That extra weight makes it feel more planted rather than flickable. Its riding position also sits more upright, which is easier on your wrists on long rides.
Both bikes get disc brakes on both wheels, with ABS as standard.
Verdict
The KTM 390 Duke and the Triumph Speed 400 aren't chasing the same brief, even if their price tags now sit close together. The KTM is the sharper, more aggressive and athletic machine, built for riders who want performance and a long features list, and who don't mind paying roughly Rs 50,000 more for it. In contrast, the Triumph plays a different game. It leans on comfort, mid-range tractability and that British badge appeal, at a lower price and with a simpler feature set.
Buyers chasing thrills and technology will find more to like in the Duke. Buyers who want a relaxed, comfortable everyday motorcycle with strong fit and finish will find the Speed 400 hard to ignore.
