| 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. | Heat Buildup: The single-cylinder engine can produce noticeable heat in heavy traffic or slow-moving city rides. Harsh Ride at Low Speeds: Stiff sport suspension can make daily commuting rough on bumpy or uneven roads. Aggressive Riding Posture: The forward-leaning position can be fatiguing for longer rides or casual commuting. Fuel Efficiency: The bike’s performance comes at a cost — real-world mileage is moderate when ridden aggressively. Maintenance Costs: Premium parts and periodic services (especially for the high-performance components) can be more expensive compared to typical middleweight bikes. Limited Comfort for Pillion: The rear seat is compact and not very comfortable for longer pillion rides. |
| 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 RC 390 is a fully faired motorcycle built around a 373cc, single-cylinder, liquid-cooled engine. This engine produces close to 43 bhp and around 37 Nm of torque, and it is paired with a six-speed gearbox. The power delivery is spread across the rev range, with noticeable strength in the mid and top end, which becomes useful during highway riding and quick overtakes. The bike uses a ride-by-wire throttle system, which manages throttle input electronically, and it also comes with a slipper clutch that helps reduce sudden rear wheel movement during aggressive downshifts. The motorcycle is based on a steel trellis frame, which is designed to keep the weight low while maintaining structural strength. It is equipped with upside-down front forks from WP and a rear monoshock, both of which are tuned to handle higher speeds and cornering stability. The braking setup includes a large front disc and a rear disc, supported by dual-channel ABS. The ABS system also offers a Supermoto mode, which allows the rear ABS to be disengaged while keeping the front active. The bike rides on 17-inch alloy wheels fitted with tubeless tyres. In terms of design, the RC 390 features a fully faired body with a front section that includes a single LED headlamp and integrated indicators. The fairing is shaped to improve airflow around the rider and the engine area. The windscreen is slightly raised to provide some level of wind protection at higher speeds. The seat is split into two sections, with a slightly elevated rear portion, and the fuel tank is shaped to allow the rider to grip it while riding. The overall layout gives the bike a compact and focused appearance. The feature list includes a TFT display that shows information such as speed, gear position, fuel level, and trip data. It also supports smartphone connectivity for basic functions. Other electronic features include traction control, which helps manage wheel spin under acceleration. The bike has a fuel tank capacity of around 13.7 litres, and the kerb weight is approximately 172 kg. The seat height is around 824 mm, which affects how easily riders can place their feet on the ground. The riding position is set up with clip-on handlebars and rear-set footpegs, which creates a forward-leaning posture. This setup changes how the rider interacts with the bike, especially during longer rides or slow-moving traffic. Overall, the KTM RC 390 combines its engine, chassis, and electronic features into a package that is designed to deliver a certain type of riding experience, defined largely by its specifications and mechanical setup. |
| Expert Review | MotoAutiv Team | The KTM RC 390 is designed with a strong focus on performance and track-style riding, which is clear from its sharp fully faired design and aggressive riding posture. The low clip-on handlebars and rear-set footpegs place the rider in a forward-leaning position, offering better control at higher speeds but making slow city rides feel a bit demanding. Its 373cc single-cylinder engine delivers quick and energetic acceleration, especially in the mid and top range, and responds well to throttle inputs during overtakes or highway riding. The six-speed gearbox, along with a slipper clutch, helps in smoother shifts and better control while downshifting. Handling is one of its key strengths, with the bike feeling stable in corners and composed at higher speeds, supported by a lightweight frame and well-tuned suspension. Braking is predictable and confidence-inspiring, with disc brakes and dual-channel ABS adding to safety. It also comes with modern features like a TFT display and ride-by-wire throttle, though the overall setup leans more towards performance than everyday comfort, with a firm seat and committed riding position., 4.2, MotoAutiv Team |
