| Cons | Despite the larger engine, performance remains commuter-oriented and does not feel particularly exciting at higher speeds. The motorcycle uses a front disc and rear drum brake setup, but braking performance is still tuned more for regular commuting than aggressive riding. The design is functional rather than premium, and some buyers may find the styling too utilitarian compared to modern 125cc commuters. The instrument cluster is basic and lacks features such as Bluetooth connectivity, navigation, or advanced digital displays. Engine vibrations can become noticeable when the motorcycle is ridden near its top speed for extended periods. The suspension is comfort-focused, which means handling feels stable but not especially sharp during fast cornering. Highway cruising ability is better than smaller commuter bikes, but the motorcycle is still primarily designed for daily transportation rather than long-distance touring. Since the model has been discontinued in India, availability of certain body panels, graphics, or model-specific cosmetic parts may become more limited over time compared to current-production motorcycles. | Not road legal and suitable only for off-road tracks. High maintenance due to 2-stroke engine rebuilds. Kick-start only, no electric start option. Relatively expensive compared to other youth dirt bikes. Small fuel tank limits long riding sessions. |
| Detailed Overview | The Bajaj CT 125X is a commuter motorcycle that has been developed with an emphasis on practicality, durability, and everyday usability. While it shares the basic purpose of most commuter bikes, providing economical transportation, it introduces several design elements that make it stand apart from conventional city-focused commuters. Features such as a metal bash plate, fork gaiters, crash guards, and semi-knobby tyres give the motorcycle a more rugged appearance and highlight its focus on handling rough road conditions alongside regular urban commuting. Powering the motorcycle is a 124.4cc single-cylinder, air-cooled engine paired with a 5-speed gearbox. The engine is tuned to deliver usable low and mid-range performance rather than aggressive acceleration. This tuning allows the motorcycle to respond smoothly in city traffic and makes it easier to ride at everyday speeds. Compared to smaller 100cc commuter motorcycles, the additional engine capacity provides improved pulling power, which can be useful when carrying a pillion rider, transporting luggage, or riding on inclines. The 5-speed transmission also helps maintain a more relaxed engine speed during longer rides and moderate highway usage. Fuel efficiency remains an important part of the motorcycle’s overall character. Real-world mileage generally falls in the range of approximately 55–65 km/l depending on riding habits, traffic conditions, and maintenance. Combined with its 11-litre fuel tank, the motorcycle offers a riding range that suits riders who cover substantial distances as part of their daily routine. The riding posture is designed around comfort and control. A wide handlebar, upright seating position, and neutral footpeg placement create a natural riding triangle that does not place excessive strain on the rider. The seat is long and reasonably spacious, allowing both rider and pillion to sit comfortably during daily commutes. These ergonomics make the motorcycle suitable for prolonged periods of use in urban environments and on mixed road surfaces. Suspension duties are handled by telescopic front forks and dual rear shock absorbers. The setup is tuned primarily to absorb uneven surfaces and reduce the impact of potholes, speed breakers, and damaged roads. This suspension configuration works together with the motorcycle’s relatively high ground clearance, allowing it to travel over rough patches without frequent contact between the underside of the bike and the road surface. The semi-knobby tyre pattern further contributes to the motorcycle’s ability to maintain grip on mixed terrain, including gravel roads and less-developed routes. Visually, the CT 125X follows a straightforward and functional design philosophy. The bodywork remains simple, but the addition of protective elements and contrasting graphics creates a tougher appearance than a typical commuter motorcycle. Alloy wheels, tank pads, and practical utility-focused components contribute to the overall design theme without significantly increasing complexity. Braking performance varies depending on the variant, with front disc and drum brake options offered during its production run. The motorcycle uses Combined Braking System (CBS), which distributes braking force between the wheels to improve stability during braking. Tubeless tyres add another practical element by reducing inconvenience in the event of minor punctures. The feature list remains focused on essential functionality. The instrument cluster provides basic riding information in a simple and easy-to-read format, while electric start functionality improves convenience during daily use. Unlike premium motorcycles, the CT 125X does not rely heavily on advanced electronics or connected technologies, instead maintaining a straightforward mechanical setup aimed at routine transportation and ease of ownership. | 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 CT 125X feels like a motorcycle developed for riders who need something tougher than a typical city commuter without moving into a larger or more expensive segment. Its 124.4cc engine provides a noticeable improvement in pulling power over most 100cc commuters, making daily riding with a pillion or luggage feel less demanding. The suspension setup is tuned for comfort, and the higher ground clearance, bash plate, fork gaiters, and semi-knobby tyres give the bike a practical advantage on broken roads and rural routes. The riding posture remains upright and relaxed, which helps during long hours of commuting. Rather than focusing on modern technology or sporty performance, the CT 125X prioritizes durability, simplicity, and ease of ownership. Features remain basic and highway performance is limited by commuter-bike standards, but the motorcycle is clearly aimed at riders who value robustness and everyday usability above everything else., 4.3, MotoAutiv Team | The KTM 85 SX is a small motocross bike built mainly for young riders who are moving up from smaller machines. It uses an 85cc two-stroke engine that feels quick and lively, especially in the mid to high rev range, but it does require regular gear shifting to keep it in the power band. The lightweight frame and compact size make it easy to handle on dirt tracks, and it feels agile while taking corners or jumps. The suspension setup is firm and designed for racing conditions, so it works well on rough tracks but can feel a bit stiff on slower or uneven surfaces. Braking performance is sharp and responsive, which helps in controlling speed during aggressive riding. Since it is a performance-focused dirt bike, it needs frequent maintenance compared to regular bikes, especially because of the two-stroke engine. Overall, the KTM 85 SX is focused on track use, with a strong emphasis on performance, handling, and control for riders who are still developing their skills., 4.0, MotoAutiv Team |
