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. High Power-to-Weight Ratio: The 249.9 cc 4-stroke engine produces very strong power, and the bike is quite light — making it very agile and fast. Advanced Electronics: Comes with launch control, two engine maps, traction control, and quickshifter — very race-oriented features. Premium Suspension: Uses WP XACT forks and rear shock (310 mm / 300 mm travel) that are very capable for jumps and rough track terrain. Excellent Chassis Flex & Control: Updated frame in newer models improves flex, which helps in cornering and gives more control. Electric Start: Equipped with a self-starter (lithium-ion battery), which is very handy on the track. Strong Brakes & Clutch: Uses Brembo hydraulics for the clutch and good brake setup — helps with precise control under race conditions. Good for Track Riders: Designed for serious motocross use — responsive, fast, and optimized for racing-style riding.
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 250 SX‑F is a purpose-built motocross machine that combines race-ready performance, lightweight agility, and advanced electronics to deliver an exhilarating experience for serious off-road riders. As part of KTM’s renowned motocross lineup, the 250 SX‑F is designed for track dominance, providing the perfect balance of power, handling, and precision for competitive riding. Its 249.9 cc, four-stroke, single-cylinder, liquid-cooled engine is tuned to deliver strong, high-revving power that is immediately responsive to throttle inputs. This makes it exceptionally capable on tight corners, jumps, and technical track sections, giving riders a confident and aggressive edge in race situations. One of the standout features of the 250 SX‑F is its lightweight chassis. The bike benefits from KTM’s proprietary trellis frame, which offers a perfect blend of stiffness and controlled flex. This results in excellent stability at high speeds while also allowing precise feedback through the handlebars and footpegs. The frame’s low weight, combined with the compact engine, ensures the bike is agile and easy to maneuver—qualities that are especially important when navigating tight motocross tracks or technical off-road terrain. The overall kerb weight remains impressively low, which reduces rider fatigue and enhances the bike’s responsiveness. The 250 SX‑F’s suspension system is another highlight. It features WP XACT 48 mm inverted front forks and a WP XACT rear shock with linkage, delivering around 310 mm of front travel and 300 mm of rear travel. This setup allows the bike to absorb big jumps, handle rough terrain, and maintain traction even under extreme stress. Both the forks and the rear shock are fully adjustable, enabling riders to fine-tune the bike for their preferred riding style or track conditions. The combination of suspension, frame geometry, and lightweight design makes the KTM 250 SX‑F exceptionally capable at both high-speed sections and technical, slower parts of the track. Modern electronics further enhance the riding experience. The 250 SX‑F is equipped with launch control, which optimizes starts and reduces wheel spin. Additionally, it offers selectable engine maps and traction control, providing riders with the ability to adapt the bike’s power delivery to track conditions or personal preference. The inclusion of a quickshifter enables seamless clutchless gear changes, maintaining momentum during aggressive racing. While minimal compared to street motorcycles, these electronic aids give riders an advantage without sacrificing the raw, track-focused feel that motocross enthusiasts demand. The ergonomics of the 250 SX‑F are designed with performance in mind. A tall seat height, wide handlebars, and a compact, upright riding position make it ideal for both sitting and standing on the pegs, which is essential for maneuvering over rough terrain and jumps. The bike also features an electric start, a convenience that eliminates the need for kick-starting and enhances usability on the track. Despite its racing pedigree, the 250 SX‑F comes with some compromises. Its fuel tank is relatively small, limiting the bike’s range to short race sessions rather than long trail rides. Maintenance is more frequent compared to casual dirt bikes, as high-performance components require careful attention. The tall seat height may also challenge shorter riders, and its race-oriented suspension can feel harsh on less demanding trails. In summary, the KTM 250 SX‑F is a high-performance motocross machine designed for riders who demand precision, agility, and race-ready power. Lightweight, technologically advanced, and built with competition in mind, it offers an exhilarating experience for those seeking to dominate motocross tracks. It is not a casual trail bike, but for dedicated racers and serious off-road enthusiasts, it stands out as one of the most capable and exciting 250-class motocross motorcycles on the market.
