Speed 400 MY25 – Full Review, Price, Mileage & New Updates Explained

When the Triumph Speed 400 first dropped anchor in India, it wasn’t just another motorcycle launch; it was a seismic event. This wasn’t a slightly tweaked model—it was an all-new launch resulting from the strategic collaboration between the iconic British brand, Triumph, and India’s manufacturing powerhouse, Bajaj Auto. The goal was clear: to bring the quintessential Triumph roadster experience, complete with high performance and premium finish, to the accessible 300cc-450cc segment.

The MY25 (Model Year 2025) version continues this legacy, largely retaining the successful platform while adding subtle refinements and new colour schemes to keep the momentum going. This bike is pitched directly at those who want the prestige of a global premium brand without the crippling price tag.

The Triumph Speed 400 MY25 starts at an aggressive Ex-showroom price of ₹2,33,754, which immediately positions it as one of the best value-for-money propositions in the market. We rode it through peak city traffic and open highways to see if it truly lives up to the hype of being an approachable yet performance-packed modern classic.

EXTERIOR DESIGN & ROAD PRESENCE

The Speed 400 is a masterclass in modern classic design, taking clear inspiration from its larger sibling, the Speed Twin.

The Signature Triumph Look

• Proportions: It maintains the clean, stripped-back roadster stance. The lines are simple, taut, and perfectly balanced. It’s compact enough for the city but has enough road presence to not be overshadowed by larger bikes.
• Premium Detailing: Triumph has not skimped on quality. The fit-and-finish are truly segment-defining. You get a proper metal fuel tank, premium paint finishes (especially the vibrant Racing Yellow option), and exquisite touches like the subtly integrated Triumph branding on the engine casing and the finned head.
• Lighting: The signature round LED headlamp with the distinctive DRL (Daytime Running Light) is a clear style statement and provides excellent illumination at night. The sleek LED indicators and tail lamp complete the modern look.

Build Quality

From the high-quality switchgear to the flawless welding on the frame and the gold anodised 43 mm USD forks, everything feels substantial and durable. This is where the Speed 400 truly distances itself from most of its price rivals; it feels like a product built to a higher global standard. It absolutely turns heads on the road, often getting mistaken for a much larger, more expensive Bonneville series motorcycle.

INTERIOR, COMFORT & FEATURES

The rider’s cockpit perfectly blends retro appeal with modern necessity.

Dashboard & Features

• Instrument Cluster: It utilizes a classy analogue speedometer integrated with a multi-function LCD screen. The analogue dial is visually appealing, while the screen provides essential data like the gear position indicator, fuel gauge, odometer, trip meters, and tachometer. While effective, the lack of a full-TFT display and dedicated turn-by-turn navigation (which some rivals now offer) is a slight miss for a modern machine.
• Technology Highlights:
  • Ride-by-Wire Throttle: Delivers precise, smooth, and predictable acceleration.
  • Switchable Traction Control (TC): A critical safety net, particularly on wet or dusty Indian roads. It can be easily switched off if the rider prefers.
  • Torque-Assist (Slip & Assist) Clutch: This is a major boon. It makes the clutch lever feather-light—a blessing in stop-go city traffic—and prevents wheel hop during aggressive downshifts.
  • USB-C Charging Port: A neat addition for on-the-go device charging.
  • Accessory-Ready: It’s pre-enabled for accessory-fit heated grips, highlighting its global standard.

Comfort & Ergonomics

• Seating: The 790 mm seat height is highly accessible and ensures most Indian riders can comfortably flat-foot the bike. The slim waistline further aids feet-down manoeuvring.
• Riding Position: The riding triangle is a near-perfect balance: slightly aggressive but fundamentally upright. It is comfortable for the daily city grind and perfectly manageable for a weekend long-distance breakfast ride. The seat itself is firm but well-cushioned.
• Space: Being a roadster, the pillion seat is adequate but not luxurious for very long hauls. Overall rider comfort is excellent for the target audience.

ENGINE PERFORMANCE & DRIVING DYNAMICS

The 40 PS TR-Series engine is what truly sets the Speed 400 apart. It’s a modern engine—free-revving, smooth, and potent.

City Drive (Agility and Tractability)

• Clutch/Steering: The clutch is unbelievably light, making the urban crawl effortless. The 176 kg wet weight feels incredibly manageable, and the bike is surprisingly easy to park and manoeuvre in tight spots.
• Low-End Torque: Unlike some high-revving rivals, the Speed 400 has a strong mid-range torque curve (peak 37.5 Nm@6500 rpm). This means you don’t have to constantly downshift. It pulls cleanly from low speeds in higher gears, making it a very relaxed commuter.

Highway Drive (Refinement and Power)

• High-Speed Stability: This is a highlight. The perimeter frame, the chunky 43 mm USD forks, and the precise tuning give the Speed 400 fantastic stability even at 110 kmph+. It feels planted and inspires confidence during fast cornering.
• Performance: The bike can hit 100 kmph quickly and cleanly, making overtakes on the highway punchy and effortless. It can happily cruise at triple-digit speeds without feeling strained. Crucially, the vibrations are well-controlled, only becoming noticeable at the very top of the rev range, showcasing excellent engineering and refinement.
• Suspension: The suspension tune is on the firmer side for sporty handling, yet the 140 mm front and 130 mm rear travel are adequate. While it might not glide over large speed breakers like a dedicated ADV, the suspension absorbs potholes easily and handles typical Indian road undulations without rattling the rider.

SAFETY (Crucial Section)

The Speed 400 is loaded with essential safety features, a non-negotiable for a modern performance motorcycle.

• Braking Hardware: The braking system is superb. A large 300 mm disc up front with a four-piston radial caliper and a 230 mm rear disc provide sharp, predictable, and confidence-inspiring stopping power.
• Electronic Aids: Dual-Channel ABS (Anti-lock Braking System) is standard, preventing wheel lock-up under hard braking. The inclusion of Switchable Traction Control is a top-level safety feature that protects the rider on slippery surfaces.
• Build Quality: While the Speed 400 has no official Global NCAP Rating for bikes, the solid feel, premium componentry (Bosch ABS, ByBre brakes), and robust frame construction suggest high structural integrity.

REAL WORLD MILEAGE (The Truth)

The mileage for a 40 PS single-cylinder bike is surprisingly decent, though riding style will heavily influence the numbers.

Condition	ARAI Claimed Mileage	Real World City Mileage	Real World Highway Mileage
Speed 400 MY25	30 kmpl	24 to 27 kmpl	28 to 32 kmpl

Export to Sheets

The ARAI Claimed Mileage is 30 kmpl. The real mileage in city traffic is around 25−27 kmpl. This figure might drop slightly if you’re stuck in bumper-to-bumper traffic like in Bangalore or Mumbai, due to the liquid-cooled engine’s nature. On the open highway, if you maintain a steady speed of 85−95 kmph, you can easily hit 30 kmpl or more. For the performance it offers, this is highly acceptable, especially when compared to the thirstier high-performance naked rivals.

Winner: Value For Money (VFM)?

• The KTM 390 Duke is the undisputed performance king, loaded with segment-best electronics and power, but it comes at a substantial premium, and its aggressive nature is less suited for relaxed commuting.
• The Harley-Davidson X440 focuses on classic thump, low-end torque, and road presence. It is heavier and significantly less powerful than the Triumph.
• The Triumph Speed 400 MY25 strikes the perfect balance. It is nearly as powerful as the Duke, yet its engine is more refined and tractable for city use. It offers a much higher quality feel and better features (like TC) than the Harley at a more competitive price point. The Speed 400 is the clear winner for Value For Money, offering premium performance and brand legacy without the premium price tag.

FINAL VERDICT

The Triumph Speed 400 MY25 is, without a doubt, a game-changer. It sets a new standard for build quality and engine refinement in the sub-450 cc roadster category. It’s the perfect blend of modern performance and timeless style, equally adept at navigating urban congestion and munching highway miles.

Buy it if:

• You want a premium, refined, and powerful engine with 40 PS that is easy to manage in the city.
