| 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. | Tall Seat Height: At 825 mm, the seat may be uncomfortable or difficult to reach for shorter riders, especially off-road. Lack of Cornering ABS: Unlike the standard 390 Adventure, the X variant skips cornering ABS, which reduces safety margin when leaning hard. Limited Traction Control: Fewer electronic aids compared to higher-spec ADVs, could be less forgiving on unpredictable terrain. Vibrations at High RPMs: The single-cylinder engine can produce noticeable vibrations when pushed hard, affecting comfort. Moderate Wind Protection: The windscreen and fairing design might not deflect wind strongly enough at high speeds. Suspension Can Feel Harsh on Pavement: While great off-road, the long-travel suspension may feel firm or bouncy on uneven city roads. Maintenance Cost: Premium suspension components and tech might lead to higher service costs compared to simpler commuter bikes. Limited Pillion Comfort: The seat design and limited rear padding may not provide much comfort for a passenger over long distances. |
| 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. | There are some motorcycles that feel layered with features, and then there are ones like the KTM 390 Adventure X, where the focus shifts more towards the core mechanical setup. It uses a 373cc single-cylinder, liquid-cooled engine that produces around 46 PS and 37 Nm of torque, paired with a 6-speed gearbox along with a slipper clutch and quickshifter. At lower speeds, the engine feels slightly restrained, but as the revs build, it starts to respond more actively, which becomes noticeable on open roads where maintaining higher speeds feels more natural. The bike is built on a steel trellis frame, supported by long-travel suspension at both ends. It gets upside-down forks at the front and a monoshock at the rear, tuned to keep the bike stable over varying surfaces. On smoother roads and highways, the setup feels composed, while on broken patches or sharp bumps, especially at lower speeds, some of the impact comes through. With around 200 mm of ground clearance, the bike can handle speed breakers and uneven roads without much concern. The riding position is upright and fairly relaxed. A wide handlebar, neutral foot peg placement, and a flatter seat help create a posture that does not put much pressure on the rider, even over longer distances. The seat height is around 825 mm, which makes it slightly more accessible compared to the standard version, especially in city riding conditions. The kerb weight is close to 177 kg, and once the bike is in motion, it feels balanced and predictable. Braking is managed by disc brakes at both ends, supported by dual-channel ABS. The setup provides a consistent and controlled braking feel in regular riding situations. The bike rides on a 19-inch front wheel and a 17-inch rear wheel, both with tubeless tyres, a combination that keeps it stable on uneven roads while still being more suited to paved surfaces. The instrument cluster is a digital unit that shows basic riding information like speed, fuel level, gear position, and trip data in a clear layout. Compared to the standard version, the Adventure X keeps things simpler by not including features like traction control or riding modes. The focus remains on essential functionality rather than additional electronic layers. With a fuel tank capacity of around 14.5 litres, the bike offers a usable range for both daily use and longer rides. It also comes with LED lighting and a windscreen that helps reduce wind impact to some extent at higher speeds. Overall, the KTM 390 Adventure X is structured around its engine, chassis, and suspension, keeping the riding experience straightforward while still covering a mix of city roads, highways, and occasional rough surfaces. |
| Expert Review | The KTM 65 SX is a purpose-built motocross bike designed for young riders stepping into competitive racing, and its overall character reflects that focus. It is powered by a 64.9cc two-stroke engine that delivers quick and responsive performance, especially when kept in the higher rev range, which means riders need to actively manage gears to get the best out of it. The lightweight chassis, around 60 kg, makes the bike easy to control in corners and during jumps, while the chromoly steel frame adds rigidity without making it feel heavy. The suspension setup, with WP XACT forks and a fully adjustable rear monoshock, is tuned for track riding and handles bumps and landings well, though it can feel stiff at lower speeds or on uneven trails. Braking performance is strong with disc brakes at both ends, giving good stopping control during aggressive riding. Ergonomically, the bike is designed to suit growing riders, with adjustable components to fit different heights, making it adaptable over time. However, like most two-stroke motocross bikes, it requires regular maintenance and is not practical for casual riding or beginners with no prior experience. Overall, the KTM 65 SX focuses on delivering sharp handling, responsive power, and track-oriented performance for young riders who are already familiar with off-road riding., 4.4, MotoAutiv Team | The KTM 390 Adventure X is powered by a 373cc single-cylinder, liquid-cooled engine producing around 43–45 bhp and 37 Nm, paired with a 6-speed gearbox along with a slipper clutch and quickshifter. The engine feels slightly dull at lower RPMs but picks up strongly in the mid-range, making highway riding feel effortless, while in city conditions it requires more gear shifts to stay smooth. It uses a steel trellis frame with long-travel suspension that is tuned on the firmer side, offering stability at higher speeds but transmitting sharper bumps at lower speeds. The upright riding posture, wide handlebar, and 825 mm seat height make it relatively accessible, while the bike remains balanced once in motion. Braking is handled by disc brakes with dual-channel ABS, offering consistent stopping performance. Compared to the standard version, it comes with a simpler electronics setup, missing features like traction control and riding modes, but still includes essentials like a TFT display and quickshifter. With a 14.5-litre fuel tank and road-focused wheel setup, it is designed for highway use along with occasional rough roads., 4.3, MotoAutiv Team |
