| 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 250 SX‑F is a purpose-built motocross machine that combines race-ready performance, lightweight agility, and advanced electronics to deliver an exhilarating experience for serious off-road riders. As part of KTM’s renowned motocross lineup, the 250 SX‑F is designed for track dominance, providing the perfect balance of power, handling, and precision for competitive riding. Its 249.9 cc, four-stroke, single-cylinder, liquid-cooled engine is tuned to deliver strong, high-revving power that is immediately responsive to throttle inputs. This makes it exceptionally capable on tight corners, jumps, and technical track sections, giving riders a confident and aggressive edge in race situations. One of the standout features of the 250 SX‑F is its lightweight chassis. The bike benefits from KTM’s proprietary trellis frame, which offers a perfect blend of stiffness and controlled flex. This results in excellent stability at high speeds while also allowing precise feedback through the handlebars and footpegs. The frame’s low weight, combined with the compact engine, ensures the bike is agile and easy to maneuver—qualities that are especially important when navigating tight motocross tracks or technical off-road terrain. The overall kerb weight remains impressively low, which reduces rider fatigue and enhances the bike’s responsiveness. The 250 SX‑F’s suspension system is another highlight. It features WP XACT 48 mm inverted front forks and a WP XACT rear shock with linkage, delivering around 310 mm of front travel and 300 mm of rear travel. This setup allows the bike to absorb big jumps, handle rough terrain, and maintain traction even under extreme stress. Both the forks and the rear shock are fully adjustable, enabling riders to fine-tune the bike for their preferred riding style or track conditions. The combination of suspension, frame geometry, and lightweight design makes the KTM 250 SX‑F exceptionally capable at both high-speed sections and technical, slower parts of the track. Modern electronics further enhance the riding experience. The 250 SX‑F is equipped with launch control, which optimizes starts and reduces wheel spin. Additionally, it offers selectable engine maps and traction control, providing riders with the ability to adapt the bike’s power delivery to track conditions or personal preference. The inclusion of a quickshifter enables seamless clutchless gear changes, maintaining momentum during aggressive racing. While minimal compared to street motorcycles, these electronic aids give riders an advantage without sacrificing the raw, track-focused feel that motocross enthusiasts demand. The ergonomics of the 250 SX‑F are designed with performance in mind. A tall seat height, wide handlebars, and a compact, upright riding position make it ideal for both sitting and standing on the pegs, which is essential for maneuvering over rough terrain and jumps. The bike also features an electric start, a convenience that eliminates the need for kick-starting and enhances usability on the track. Despite its racing pedigree, the 250 SX‑F comes with some compromises. Its fuel tank is relatively small, limiting the bike’s range to short race sessions rather than long trail rides. Maintenance is more frequent compared to casual dirt bikes, as high-performance components require careful attention. The tall seat height may also challenge shorter riders, and its race-oriented suspension can feel harsh on less demanding trails. In summary, the KTM 250 SX‑F is a high-performance motocross machine designed for riders who demand precision, agility, and race-ready power. Lightweight, technologically advanced, and built with competition in mind, it offers an exhilarating experience for those seeking to dominate motocross tracks. It is not a casual trail bike, but for dedicated racers and serious off-road enthusiasts, it stands out as one of the most capable and exciting 250-class motocross motorcycles on the market. |
| 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 |
