| Cons | 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. | Low ground clearance & limited suspension travel: On bad or uneven surfaces, its cruiser geometry and low clearance can be a drawback, especially in markets with rough roads. Heavy weight / less agility in tight scenarios: While stable at speed, the mass and cruiser chassis make it less nimble than lighter motorcycles, especially in traffic or tighter corners. Suspension setup may feel firm/stiff: Some reviewers mention that the suspension, tuned for style and load, can feel a bit firm or less compliant than ideal for rough surfaces. Premium cost and ownership aspects: As a premium bike in its class, purchase price, maintenance and parts/spares may cost more than simpler alternatives. |
| Detailed Overview | 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. | The Triumph Bonneville Speedmaster is the kind of motorcycle that looks like it belongs to an older era, but once you start looking at the specs, you realise it’s built with modern parts underneath. It runs on a 1200 cc parallel-twin engine that makes around 78 PS and 106 Nm. What this means in real life is that the bike feels strong at low speeds. You don’t have to keep changing gears again and again in traffic, and even on highways it moves in a smooth and relaxed way rather than feeling aggressive. The riding position is very different from regular bikes. You sit low, with your legs stretched forward, and your hands on wide handlebars. It feels comfortable when the road is open, but in city traffic it can take some time to get used to, especially when you have to stop and start often. The seat height is quite low, around 705 mm, so most riders can easily place their feet on the ground, which helps when handling such a heavy bike. Talking about the hardware, the Speedmaster uses a steel frame with front telescopic forks and a rear monoshock that is hidden to keep that classic look. The suspension is tuned more for comfort, so it works fine on normal roads, but sharp bumps and bad patches are still clearly felt. The bike rides on a 16-inch front and rear wheel setup, which adds to its low and stretched design. Braking is handled by a disc at the front and rear, along with dual-channel ABS, so braking feels controlled and predictable in normal riding conditions. This is not a light bike by any means. It weighs around 263 kg, so you will notice the weight when moving it around or riding at low speeds. Once the bike is moving, it feels more stable and planted. The fuel tank is about 12 litres, which means you may need to plan fuel stops on longer rides. In real-world conditions, mileage usually stays around 18 to 22 km/l, depending on how you ride. On the feature side, the Speedmaster keeps things simple but modern enough. It gets a semi-digital instrument cluster with an analogue speedometer and a small digital screen for details like gear position, fuel level, and trip info. It also comes with riding modes, traction control, and cruise control, which can be useful on highways. There is no focus on flashy tech or connectivity, and the bike sticks to a straightforward setup. |
| Expert Review | MotoAutiv Team | With the Bonneville Speedmaster, the focus is clearly on a calm and steady riding experience rather than speed. The 1200 cc engine feels strong at low speeds, so riding in traffic doesn’t require constant gear changes, and on highways it stays smooth at a relaxed pace. The riding position is stretched out with forward footpegs, which feels natural on open roads but less convenient in crowded areas. Because of its weight, slow-speed handling needs some effort, especially in tight turns or parking. The suspension is set for comfort, but bad roads and sharp bumps are still felt. It gets basic modern features like ride modes and traction control, without too much focus on advanced electronics. In everyday conditions, it feels more suited to easy rides than regular heavy usage., 4.3, MotoAutiv Team |
