| Detailed Overview | The Bajaj Pulsar NS125 is built as a smaller-capacity motorcycle within the NS (Naked Sport) lineup, combining a compact engine with a perimeter frame and design elements inspired by larger Pulsar models. At its core, the motorcycle is powered by a 124.45 cc single-cylinder, air-cooled engine that uses a 4-valve SOHC configuration and fuel injection to manage combustion. This engine produces around 12 PS of power at 8500 rpm and 11 Nm of torque at 7000 rpm, figures that are broadly in line with other motorcycles in the 125cc segment. The engine is paired with a 5-speed manual gearbox, which allows the rider to shift through gears depending on speed and riding conditions. Power is delivered to the rear wheel via a chain drive system, a common setup in motorcycles of this category. The overall powertrain is designed to provide a mix of usable power and efficiency for everyday riding scenarios. The NS125 is built on a perimeter frame, a structure that surrounds the engine and distributes loads around it during cornering and regular riding. This type of frame is derived from larger NS models. Suspension duties are handled by telescopic front forks and a rear monoshock suspension, which work together to absorb road irregularities such as bumps and uneven surfaces. For braking, the motorcycle features a front disc brake and a rear drum brake, supported by a combined braking system (CBS). In some variants, a single-channel ABS setup is also available, depending on the configuration. The braking system is designed to distribute stopping force between the wheels to maintain balance during deceleration. The bike rides on 17-inch alloy wheels fitted with tubeless tyres, which are commonly used for road grip and ease of maintenance. This wheel setup contributes to maneuverability and stability in both city traffic and open roads. In terms of dimensions, the Pulsar NS125 has a fuel tank capacity of 12 litres, providing a riding range between refueling stops that depends on fuel consumption and riding conditions. The motorcycle has a kerb weight of around 145 kg and a seat height of approximately 805 mm. Ground clearance is around 178 mm, intended to provide clearance over uneven road surfaces and speed breakers. The instrument cluster on the NS125 is typically a semi-digital console, combining an analog tachometer with a digital display for speed, fuel level, and trip information. Some variants also include Bluetooth connectivity features, offering additional ride data and navigation-related functions through a connected device. Lighting components include a halogen or LED headlamp setup depending on variant, and an LED tail lamp, along with design elements such as the wolf-eyed headlamp styling and split grab rails. | The KTM 85 SX is one of the most popular and respected youth motocross bikes in the world, designed specifically for young riders who are ready to take the next big step toward competitive racing. More than just a beginner’s off-road bike, the 85 SX brings true race-bred DNA from KTM’s full-size SX lineup, giving upcoming racers the opportunity to experience high-level performance at an early age. With its sharp power delivery, lightweight design, and premium components, the bike is built to help young riders improve skills and confidently tackle motocross tracks. At the heart of the KTM 85 SX lies its 84.9cc 2-stroke, liquid-cooled engine, which is known for delivering punchy power and rapid acceleration. The powervalve system ensures that the engine produces strong torque across the rev range, making the bike easier to control while still offering impressive performance. Whether riders are attacking tight corners or hitting long straights, the engine responds crisply and delivers the thrilling character 2-strokes are known for. Paired with a 6-speed gearbox, the bike offers smooth shifting and plenty of flexibility for both beginners and experienced youth racers. One of the standout features of the 85 SX is its lightweight chassis, made with high-strength chromoly steel. This frame not only enhances stability but also ensures precise handling, allowing riders to maneuver confidently through jumps, whoops, and rough terrain. The ergonomics are thoughtfully designed to fit young riders, offering a slim body that allows easy movement, better grip, and improved control during aggressive riding. Suspension is another area where KTM excels, and the 85 SX is no exception. It comes equipped with WP XACT suspension, featuring an AER air fork at the front and a fully adjustable shock absorber at the rear. This setup provides excellent damping, great response on jumps, and impressive support on uneven surfaces. Riders can also fine-tune the suspension to match their weight, riding style, and track conditions — something rarely seen in youth motocross bikes. The bike also features powerful disc brakes on both ends, giving young riders the confidence to brake hard into corners. The wave-style discs help with heat dissipation, which is especially important during long practice sessions or competitive races. Lightweight wheels, grippy motocross tyres, and a race-focused design further enhance the overall performance package. In terms of ergonomics, the KTM 85 SX is designed to feel like a miniature version of the bigger SX bikes. The seat height, handlebar position, and narrow bodywork all work together to provide comfort while promoting proper riding posture. This allows young riders to develop good habits early in their riding journey. Overall, the KTM 85 SX is a bike built for serious young racers who want real performance, durability, and race-ready features. With its responsive engine, excellent suspension, strong brakes, and lightweight build, it stands out as one of the top choices in the youth motocross segment. Whether used for training or competition, the 85 SX gives riders a true taste of professional motocross performance. |
| Expert Review | The Bajaj Pulsar NS125 occupies an interesting position in the 125cc segment - it borrows the perimeter frame, monoshock rear suspension, and streetfighter styling from its larger NS siblings, which gives it a hardware advantage that most competitors at this price point simply cannot match on paper. In real-world city riding, the 124.45cc air-cooled engine delivers adequate performance for stop-and-go traffic and college commutes, though it begins to show its limitations above 80 km/h where vibrations become noticeable through the handlebar and footpegs. The claimed ARAI efficiency of 56+ km/l is optimistic, most owners report figures closer to 34–45 km/l under mixed riding conditions, which is decent but not exceptional for a 125cc motorcycle. The addition of single-channel ABS on the top variant is a genuinely meaningful safety feature for the segment, though the base and mid variants still make do with CBS, and the rear drum brake across all variants feels like a cost compromise that affects overall braking confidence. Build quality and finish are adequate for the price but fall short of what the sporty design aesthetic suggests, plastics feel thin in places and panel gaps are inconsistent on some units. At roughly ₹93,000–₹1,02,000 ex-showroom, the NS125 is reasonably positioned, but buyers willing to stretch their budget slightly will find the NS160 a considerably more complete motorcycle in terms of performance and refinement., 3.2, MotoAutiv Team | MotoAutiv Team |
