Overview
Performance And Engine
The 1252cc DOHC 60-degree V-twin engine uses forged pistons, DLC-coated finger followers, and a specially designed exhaust for quick throttle response up to its 7,500 rpm redline. On the dyno, it shows 110-112 rear-wheel horsepower and 118 Nm of torque, which means it can do a quarter-mile in about 11.5 seconds at 118 mph in ideal conditions. Twin counterbalancers keep vibrations low below 4,000 rpm, making city rides smooth. Its cooling system, with dual radiators and a high-flow pump, keeps the engine running strong even during long idles in hot traffic. The engine delivers most of its torque early, making it great for weaving through traffic or climbing hills, and it’s ready for future E85 tuning. However, it currently requires 98 octane fuel.
The gearbox uses inverted-tooth helical gears for quiet operation and a multi-plate wet slipper clutch for smooth, rev-matched downshifts. The 6-speed transmission has a strong 35mm cable pull and a low-friction shift drum. Gear ratios are set for strong launches in first gear (3.24:1) and relaxed cruising in sixth (0.89:1). The 114-tooth belt and 2.23 final drive provide efficient torque without the hassle of chain maintenance. Belt tensioner checks are needed only every 20,000 km in clean conditions, and regular oil changes keep the system reliable. Riders report no missed shifts, even when using Rain mode.
Factory speedo cap sits at 234 kmph, but GPS-verified maxima hover 228 kmph in top gear, tucked with 180-section rear rubber biting firm. Mid-range rolls dazzle: 80-140 kmph in 4th drops under 5 seconds, fueled by flat torque plateau from 4,500-6,500 rpm. Chassis geometry—28-degree rake, 97mm trail, 1,522mm wheelbase—anchors high-speed stability, shrugging off crosswinds or tar snakes; lean angle clearance hits 42 degrees left/right before scraping. Stock ergonomics fatigue arms past 180 kmph without bar risers or tall screens, but NH44 blasts reward with planted Brembo fade-free stopping from triple digits.
Mileage And Fuel Efficiency
According to ARAI’s test cycle, which mixes city and highway driving, the Sportster S claims 19.6 kmpl. This is achieved through efficient fuel injection and a variable oil pump that saves fuel after the engine warms up. The 11.80L tank (with a 1.70L reserve) gives a theoretical range of 231 km. An OBD-II port helps with real-time diagnostics. The engine is 14% lighter than older models and uses an electric water pump for better efficiency. On steady highway rides, solo riders can achieve up to 21 kmpl, but city traffic reduces mileage.
Reports from over 200 Indian owners show an average fuel efficiency of 19.2 kmpl in mixed conditions. In heavy city traffic like Bengaluru or Mumbai, mileage drops to 17-18.5 kmpl, while steady highway cruising at 85 kmph can reach 21-23 kmpl. On track days in Sport mode, it averages about 16.5 kmpl. Carrying a passenger or riding in hot weather can reduce mileage by 1.5 kmpl, while using wet mode in the monsoon can improve it by 0.5 kmpl. For example, a 2,200 km Delhi-Chennai trip used 115L of fuel at ₹102 per litre, totalling ₹11,700. The liquid-cooled engine performs about 10% better than air-cooled models in extreme heat. After the engine is run in, ECU remaps, or K&N filters can boost average fuel efficiency to 20.5 kmpl, though premium fuel is still required.

Build Quality
The Sportster S uses a strong steel trellis frame with a double-cradle design that handles potholes and rough roads without bending, keeping its weight balanced even after heavy rains. Key parts are treated with chrome and special primers, and stainless steel is used to prevent rust, especially in humid places like Kerala or Mumbai. The 11.7L tank has a polymer liner to avoid swelling from fuel. The fork lowers have a coating to keep dirt out, and the rear subframe is designed to prevent cracks when carrying passengers. Owners say the fasteners stay tight after 15,000 km, with no issues like seam gaps or paint chips.
High-quality parts help the Sportster S last longer. Brembo Stylema brakes with special pistons prevent overheating and sticking, even in dusty areas. The sealed wheel bearings work smoothly for over 30,000 km, and the automatic belt tensioner means less maintenance. The wiring uses waterproof connectors to handle water crossings, and the swingarm’s forged aluminium pivot keeps the ride tight on rough roads. Tests show the engine mounts reduce vibrations at idle, and there are no reports of oil leaks or gasket problems in the first year.
Handling
With a 28-degree rake, 97mm trail, and a 1,522mm wheelbase, the Sportster S stays steady at 180 kmph on highways but is still easy to handle in city traffic. The 43mm inverted forks offer 120mm of travel and can be adjusted for different loads. The rear monoshock also adjusts and provides smooth damping over bumps. The Dunlop tyres grip well on wet or rough roads, even at sharp lean angles. The mid-mounted controls and 765mm seat height make it easy for riders around 70kg to balance at stops, and the frame stays responsive despite the bike’s weight.
Electronic features make the ride safer and more controlled. Cornering traction control helps on slippery surfaces, and drag-torque slip control keeps the bike stable during sudden throttle changes in tight turns. The tyre pressure monitoring system warns you of pressure drops before they become a problem. The bike accelerates quickly from 60 kmph with little squat, and the front brake gives good feedback when slowing into corners. Its low centre of gravity makes tight U-turns easy, which is useful in crowded city areas.
Comfort
The Sportster S is comfortable for solo riders, with a 765mm seat height and narrow tank rails that fit riders from 5’4″ to 6’2″. The 18-inch-wide seat uses high-quality foam to prevent numbness on long rides. Rear-set pegs give plenty of knee room for long highway trips, and the mini-ape handlebars help keep your shoulders relaxed and reduce wind strain on your neck. Rubber-mounted balancers keep mirrors clear and footpegs vibration-free up to 140 kmph. For passengers, there are aluminium grab rails, recessed pegs, and an optional backrest for comfortable two-up rides up to 300 km.
The suspension is designed to handle bumps smoothly, whether riding alone or with extra weight. The front forks use triple-rate springs, and the rear linkage absorbs sharp shocks, so you don’t feel jolts in your back. Adjustable rebound keeps the ride stable after dips. The tank cowl helps deflect wind below your chin at 120 kmph, bar-end weights reduce handlebar vibrations, and the seat’s mesh keeps you cool in hot weather. Riders have reported staying dry on long rides, unlike others who end up sweaty. Optional extras like a tall windscreen and heated grips make the bike more comfortable in the monsoon, and the sidestand is designed for stable parking on sloped surfaces.
Styling
The Sportster S has a bold, blacked-out look with a short front fender, a compact fuel tank cowl that directs wind over the rider, and a high-mounted exhaust that gives it an aggressive stance. The mid-mounted controls and low seat create a forward-leaning riding position, while blacked-out forks, Brembo brakes, and alloy wheels add to its style. The LED headlamp with DRL delivers strong nighttime illumination. The trellis frame is visible through the minimal bodywork, showing off the V-twin engine and belt drive. This mix of classic Sportster and modern superbike design makes it stand out both in showrooms and on the road.
The Sportster S is compact, measuring 2,175mm long and 965mm wide, with 150mm of ground clearance to easily handle speed bumps. The tail section is slim, with an LED taillight and an underbelly exhaust that protects against road debris. Upright handlebars with risers make for comfortable cruising, and the tank graphics blend smoothly into the side covers. Matte finishes on the engine cases help hide fingerprints. The bike looks sporty and powerful without being bulky, making it a great choice for riders who want to show off their style at meets or cafes.

Value For Money And Pricing
The Sportster S starts at ₹ 18,05,000 ex-showroom in India and comes with eye-catching two-tone graphics and bronze accents. Its 121 hp and 125 Nm liquid-cooled V-twin engine delivers twice the power of many rivals, along with advanced features such as a TFT display, cornering ABS, traction control, adjustable Showa suspension, and Brembo brakes. The bike keeps 85-90% of its value after the first year, thanks to strong demand. Service is needed every 8,000 km and costs ₹12,000-15,000, but reliability helps offset these costs. With a real-world mileage of 19 kmpl, annual fuel costs are about ₹45,000 for 10,000 km.
Owners love the strong torque for highway overtakes, the modern electronics that work well in the monsoon, and the prestige that cheaper imports lack. While the pillion seat is a bit firm, most riders feel the daily excitement makes up for it. It’s a smart choice for those moving up from 500cc bikes who want superbike performance without the bulk of a touring bike.
