Overview
Performance And Engine
The Triumph Speed T4 comes with a liquid-cooled, single-cylinder 349cc engine that uses a DOHC 4-valve setup. With an 89mm bore and 56.1mm stroke, it has a high 12.1:1 compression ratio for better efficiency. The engine makes 29 PS (21.33 kW) at 7500 rpm and 31 Nm of torque at 5500 rpm. It uses Bosch electronic fuel injection and a wet multiplate A&S clutch for smooth gear changes. This setup gives strong performance from low revs, making it great for city traffic and longer highway rides. The engine meets BS6 OBD2B standards, keeping emissions low and delivering a unique exhaust sound, ideal for riders who want both reliability and character, even amid India’s changing fuel quality.
The 349cc TR-series engine delivers 85% of its 31 Nm peak torque from just 2500 rpm, giving strong mid-range power for quick overtakes and easy cruising. At 7500 rpm, it reaches its full 29 PS, allowing for lively acceleration. Real-world tests show 0-100 kmph in about 6.5 to 7 seconds, and the engine stays smooth with minimal vibrations up to 100 kmph. Updates like a heavier flywheel and new ECU mapping help with smoother low-speed response and less heat during long summer rides. The exhaust has a deep sound that meets noise rules but still feels exciting. Riders like the smooth power delivery, which avoids sudden surges, making it easy to ride in traffic without constant gear changes.
The 6-speed gearbox works smoothly with the engine and has wide gear ratios, making highway rides at 80-100 kmph easy without high revs. The torque-assist slipper clutch helps prevent wheel hop and keeps the bike stable during hard downshifts, which is useful in city traffic or on rough roads. The strong 102-link endless O-ring chain needs oiling every 500-1000 km in India’s dusty and humid conditions. The gear selector is precise, so shifts feel light and positive, even when the bike is cold. This setup makes it easy to move from slow city traffic to efficient highway cruising, making the ride smooth for both daily commuters and long-distance riders.
In real-world tests, the Speed T4 reaches a top speed of 137 kmph, with some GPS-verified runs hitting 150 kmph on open roads. The bike stays stable up to 140 kmph, helped by its 193 kg weight and upright riding position, though wind makes it hard to keep high speeds for long. Riders on highways like NH66 in Kerala say it cruises comfortably at 120-130 kmph with little vibration. Some have seen up to 170 kmph on the speedometer (about 155 kmph by GPS) before the power drops off. Things like rider weight, wind, and elevation can change these numbers, but the T4 is faster than many 300cc bikes while still being practical.
Mileage And Fuel Efficiency
ARAI tests show the engine gives about 30 kmpl under standard conditions, with low CO2 emissions of 72.8 g/km. This good mileage comes from smart fuel mapping, light engine parts, and a 13L tank, which means you can go over 390 km on a full tank—great for trips between cities. The bike meets BS6 OBD2B rules, so it runs well without needing frequent updates, and the fuel injection system adjusts to different altitudes and fuel types found in India. Indian users confirm these numbers match real-world tests, making the T4 a fuel-efficient choice in its class.
Indian riders say they get 25-29 kmpl on average, with 28-32 kmpl on highways at steady speeds and 22-25 kmpl in heavy city traffic. Some users report 21 kmpl over long distances if they ride hard or don’t maintain the chain, while others reach 29 kmpl with gentle riding and regular servicing. In Kerala’s humid weather and busy streets, solo riders usually see 24-28 kmpl, but this drops to 20-23 kmpl with a passenger or luggage because of the bike’s weight. Simple maintenance like cleaning the air filter and changing the oil can improve mileage by 2-3 kmpl, so most people can get over 300 km from a full tank.

Build Quality
The Speed T4 boasts high-quality construction matching the Speed 400, with meticulous fit-and-finish evident in its tubular steel frame, cast aluminium swingarm, and powder-coated engine components that resist corrosion in humid Indian climates like Kerala’s monsoons. Materials like the premium switchgear, LED housings, and zinc-alloy grab rails feel tactile and durable, contributing to a sense of solidity praised in users for longevity without rattles even after months of city use or 10,000+ km.
Welds on the hybrid spine/perimeter chassis are precise and clean, while 17-inch alloy wheels with precise balancing, ByBre callipers, and stainless steel exhaust shielding underscore Triumph’s engineering standards, making it stand out against rivals in rust-prone conditions and dusty trails. The 193 kg kerb weight feels substantial yet not overweight, with no panel gaps or creaks reported during aggressive testing, and the blacked-out engine casing maintains a premium sheen despite exposure to road salt and grime. Owners highlight the robust chain guard and fork boots as thoughtful additions for Indian roads, ensuring components stay protected during daily exposure to abrasive surfaces.
Handling
With a 1406mm±10mm wheelbase, 24.2° rake, 110mm trail, and revised steering geometry from the Speed 400, the Speed T4 offers nimble low-speed manoeuvrability, ideal for tight Kerala traffic or Mumbai U-turns, and flicks direction changes effortlessly despite conventional forks. The longer wheelbase enhances straight-line stability at 80-120 kmph on NH66 highways, while 110/70-17 front and 140/70-17 rear tubeless tyres provide confident grip on undulating bitumen, gravel patches, or wet asphalt without feeling twitchy or under-damped.
Users note its balanced chassis absorbs inputs accurately, remaining composed over expansion joints, speed breakers, and flowing corners up to 100 kmph, aided by 170mm ground clearance that prevents footpeg scraping on broken village roads or speed humps. The neutral weight distribution (roughly 50:50) allows easy leaning transitions, with progressive feedback through the wide handlebars, making it forgiving for novice riders yet rewarding for enthusiasts tackling ghat sections. At higher speeds, minimal head shake and quick recovery from bumps showcase the swingarm’s compliance, outperforming softer rivals in mid-corner stability without requiring constant corrections.
Comfort
Ergonomics shine with an 806mm seat height and slim 150mm waistline, allowing easy flat-footing for riders from 5’4″ to 6’2″, complemented by well-padded solo (multi-layer foam) and pillion seats that cushion 200+ km rides without numbness or hotspots. The upright posture from 827mm-wide handlebars and neutral footpegs reduces wrist and back fatigue during daily 50 km commutes, while the 43mm telescopic forks (140mm travel) and preload-adjustable twin monoshocks (120mm travel) deliver plush compliance over potholes, railway tracks, or cobbled streets, transmitting minimal harshness to the spine even fully loaded.
Owners report relaxed highway cruising at 90-110 kmph, with low vibes up to 100 kmph, thanks to a heavier flywheel and rubber-mounted pegs. Wind protection is limited beyond 120 kmph without a screen; rearset pillion grab rails and spacious footwells enhance two-up usability for family outings. The seat’s slight forward bias prevents sliding on climbs, and adjustable rear preload accommodates solo or laden touring across India’s heatwaves, with minimal heat from the air-cooled cylinder heads reaching thighs in stop-go traffic. Long-term tests confirm fatigue-free ergonomics for 8-hour days, ideal for delivery riders or weekend tourers navigating urban sprawl to coastal highways.
Styling
The Speed T4’s design draws directly from Triumph’s iconic Speed lineage, featuring a round LED headlamp with a distinctive integrated DRL signature that glows elegantly at dusk, a sculpted teardrop fuel tank with bold diagonal split graphics evoking 1970s customs, and a ribbed single-piece seat cover upholstered in premium black vinyl for an authentic roadster vibe that turns heads in crowded bazaars or open highways. Blacked-out elements dominate with a matte-finished 349cc engine casing, upswept dual exhausts tucked high for ground clearance, 17-inch 10-spoke cast aluminium alloys in gloss black, minimalist bar-end mirrors, and sturdy pillion grab rails, creating a stealthy yet premium finish that hides its accessible price point.
The compact tail section integrates a slim LED taillight with a clear lens, number plate recess, and barely-there rear fender for an uncluttered retro-modern appeal, while brushed aluminium tank badges, chrome throttle body accents, and subtle ‘Speed T4’ script on the side panels add heritage detailing without overwhelming the clean lines. The upright riding stance, 170mm ground clearance, and slim 150mm waistline make it visually approachable for Indian streets, earning consistent praise from users for lines that resist visual ageing compared to flashier neo-retro rivals like the Royal Enfield Hunter or Honda CB350, blending café racer poise with everyday practicality.
Colour Options And Variants

The paint is durable and tested to resist fading in India’s strong sun, and it’s available at over 230 Bajaj-Triumph dealers, making it easy to find matching accessories like tank pads or custom seats.
The Speed T4 is sold only as a single Standard variant in India, so buyers don’t have to choose between different versions. It comes with the same features for everyone, including the 349cc TR-Series engine, regular telescopic forks, dual-channel ABS, full LED lighting, and USB-C charging. Unlike other bikes with many trims, there are no higher-spec versions here. Features like USD forks, ride-by-wire throttle, traction control, or Bluetooth are left out to keep the price low, making this the most affordable Triumph roadster. This simple approach is aimed at first-time buyers moving up from 200cc bikes. The T4 is available across India through Bajaj-Triumph’s large network, with a standard 2-year unlimited km warranty, 16,000 km or 12-month service intervals, and roadside assistance.
Value For Money And Pricing
The Speed T4 is sold as a single Standard variant for ₹ 1,99,139 ex-showroom (Delhi), with a small price increase of about ₹3,000 in January 2026 to ₹1,92,000 due to inflation. It’s still the most affordable Triumph. EMI plans start at around ₹5,500 per month for 3 years at 9.7% interest through Bajaj Finance. There are festive deals like zero down payment or free accessories at over 230 dealers. All colours cost the same, and you can get an extended warranty for up to 5 years for about ₹8,000-12,000, making it a good value for city buyers.
The Speed T4 offers features usually found on bikes costing over ₹2.5 lakh, such as a premium build, a 29 PS 349cc BS6 engine, dual-channel ABS, full LED lighting, and a 6-speed A&S gearbox. It keeps most of the Speed 400’s appeal, including its looks and handling, but costs ₹23,000 less. You get real-world mileage of 25-29 kmpl, a 13L tank for about 350 km range, and a 2-year unlimited km warranty, making it easy to own even as fuel prices rise. The use of regular forks and no traction control helps keep the price down and gives better resale value than Royal Enfields. Service intervals are every 16,000 km, which lowers long-term costs by 20-30% compared to rivals needing checks every 5,000 km. Users praise its strong low-end torque for city riding, tough parts for monsoon weather, and high resale value (85% after one year), making it a smart choice for buyers moving up to their first premium bike.
