| Cons | High maintenance: being a 2-stroke race bike, it needs frequent servicing and top-end rebuilds. Costly parts: replacement parts (especially race-specific ones) can be expensive. Kick-start only — no electric starter, which may be difficult for smaller/younger riders. Limited fuel capacity: small fuel tank means more frequent refuels. Size limitations: while great for its class, more advanced or heavier riders may outgrow it soon. Not road legal — strictly made for off-road/motocross use. | Firm (harsh) ride: The suspension can feel stiff over potholes or uneven surfaces, which may be tiring for long rides. Limited wind protection: Being a naked bike, you feel a lot of wind at highway speeds, making long-distance touring less comfortable. Engine heat: In slow or stop-go traffic, the radiator fan can dump hot air toward the rider’s legs, which many find uncomfortable. Seat comfort: The stock seat can feel firm and less comfortable for long rides; also, pillion comfort is limited. Vibration: Some riders report noticeable vibrations in certain RPM ranges, especially between ~4,500–6,000 rpm. Reliability concerns: There are occasional reports of reliability issues or quality control, especially in older models. |
| Detailed Overview | The KTM 65 SX is one of the most iconic and trusted youth motocross bikes in the world, built for young riders who are ready to step into competitive racing. Designed as a bridge between mini dirt bikes and full-size motocross machines, the 65 SX gives young racers the taste of real racing performance with features inspired directly from KTM’s bigger SX lineup. For many aspiring riders, this bike marks the beginning of a serious motocross journey. At the core of the KTM 65 SX is its 64.9 cc 2-stroke, liquid-cooled engine, designed to deliver smooth yet powerful performance. The engine is known for its sharp throttle response and punchy powerband, which helps riders tackle jumps, corners, and straights with ease. With its race-tuned powervalve system, the bike offers strong torque and acceleration across the rev range, making it highly competitive on the track. The 6-speed gearbox paired with a hydraulic clutch further enhances control, allowing young riders to shift smoothly and confidently during intense racing situations. One of the major highlights of the 65 SX is its lightweight chassis, which gives the bike excellent agility. Weighing just around 53 kg, it allows young riders to maneuver easily, even in technical sections. The frame is built using high-strength chromoly steel, offering a perfect balance of rigidity and flexibility. This helps maintain stability during high-speed riding while still giving enough flex to absorb rough terrain. Suspension plays a huge role in motocross, and KTM has equipped the 65 SX with premium WP XACT suspension. At the front, it features a 35 mm AER air fork, which allows easy adjustment based on the rider’s weight and riding conditions. At the rear, a fully adjustable WP monoshock ensures consistent damping performance. This suspension setup works beautifully on jumps, whoops, and rutted tracks, making the bike feel planted and confidence-inspiring. Braking is equally impressive, with hydraulic disc brakes on both ends providing sharp stopping power. This is especially important for young racers learning advanced braking techniques such as trail braking and hard corner entries. The wave-style discs also help manage heat buildup during longer motos. The ergonomics of the KTM 65 SX are carefully designed to suit growing riders. The seat height, footpegs, and handlebar position give young riders a natural and balanced stance, allowing them to ride longer with less fatigue. The slim bodywork also makes it easier for riders to shift their weight when cornering or navigating obstacles. Another advantage is its “grow-with-the-rider” setup. Many components, including the handlebar and suspension, can be adjusted, making the bike suitable for a range of ages and sizes. This is one of the reasons why parents and young racers prefer the 65 SX — it adapts as the rider’s skills and physical size improve. Overall, the KTM 65 SX is a race-ready machine built to deliver high performance, reliability, and confidence to young riders entering the world of competitive motocross. With its strong engine, agile handling, premium suspension, and race-focused design, it remains one of the best choices for aspiring motocross champions. | The **KTM 390 Duke** has long been celebrated as a high-performance yet lightweight streetfighter, offering a compelling mix of power, agility, and modern technology that makes it a favorite for both urban commuting and spirited weekend rides. The latest (Gen-3) 390 Duke takes this formula further, built on a newly designed trellis frame with a die-cast aluminium sub-frame that improves rigidity and handling. Under the hood, the 2024 model is powered by a liquid-cooled, single-cylinder “LC4c” engine now displacing **399 cc**, which bumps up the performance to roughly **46 PS of power and 39 Nm of torque** in the Indian spec. One of the most striking traits of the 390 Duke is its lightness: the new model continues to boast sporty handling thanks to its steel trellis frame and a compact, aggressive footprint. The WP APEX 43 mm upside-down front fork and a preload-adjustable WP APEX mono-shock at the rear provide a finely tuned suspension setup that balances comfort on city roads with precision in the corners. Braking is handled by a 320 mm front disc with a radial calliper and a 230 mm rear disc, supported by Bosch cornering ABS, giving reliable and controllable stopping performance. On the feature front, the 2024 Duke 390 is truly packed. It includes ride modes (Street, Rain, Track), launch control, SuperMoto ABS, a quickshifter+, and a slipper clutch. The ride-by-wire throttle ensures smooth power delivery and precise control, especially when transitioning between modes. Its 5-inch TFT display supports smartphone connectivity (via Bluetooth) for turn-by-turn navigation, calls, and media, making it a very usable bike for daily commuting. Ergonomically, the 390 Duke offers a sporty but accessible riding position. The seat height is around **800 mm** in the Indian variant, with an optional 820 mm seat available, making it relatively manageable for a variety of rider heights. The fuel tank is reasonably sized (KTM lists about 13.4 litres), which balances enough capacity for daily use without compromising on agility. In terms of usability, the 390 Duke shines in city traffic thanks to its light weight, responsive throttle, and nimble chassis. At the same time, its torque and power allow for satisfying highway stretches and sporty ride-outs. However, as some users note, the high-revving single cylinder can vibrate noticeably at lower RPMs, and the engine tends to heat up in slow, stop-go traffic — a common character point for small high-performance singles. On long highway rides, wind protection is minimal due to the naked nature, and though the electronics are rich, some may feel the bike’s seat and fuel range are not optimized for extended touring. Reliability-wise, many long-term owners report good durability when properly maintained. One rider, after 29,000 km, said he never faced major breakdowns and appreciated the bike’s consistent performance. That said, some others have expressed concern about vibration and the need for regular maintenance given the sporty nature of the engine. Overall, the **KTM 390 Duke** is a brilliant all-rounder in the 300–400 cc naked category. It offers serious performance, modern electronics, and a lightweight chassis, but it doesn’t compromise on practicality. For someone looking for a fun, aggressive bike that can do daily duties and weekend thrills, the 390 Duke remains one of the most compelling choices in its class. |
