| 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 purchase cost: As a premium “Six Days” edition, it’s more expensive than standard enduro bikes. Tall seat height: Around 963 mm, which can be difficult for shorter or less‑experienced riders. Small-ish fuel tank (~8.5 L), which may limit range in very long or remote enduro rides. Maintenance-intensive: High-performance components (valves, clutch, engine) need frequent checks and servicing. Can feel “stiff” for casual riders: The race-tuned suspension and aggressive setup may not be comfortable for easy trail riding. Reliability concerns: Some users report fueling issues (lean running), and need for aftermarket ECU or tuning. > “Bad fueling – running too lean … Most people … want a fuel tuner or aftermarket ECU.” Battery dependency: Electric start depends on the lightweight battery — if it fails, starting could be problematic. |
| 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 350 EXC-F Six Days is a premium, race-oriented version of KTM’s 350cc enduro bike, designed to deliver top-tier performance for serious off-road riders who demand both power and endurance. Constructed with high-quality components and Six Days–specific upgrades, this model embodies KTM’s racing legacy while remaining practical enough for hard enduro, cross-country, and competition-style riding. At its heart, the Six Days version uses a 349.7 cc single-cylinder, 4-stroke, DOHC engine. The engine features a Keihin EFI system with a 42 mm throttle body for precise fuel delivery and efficient performance. A wet, multi-disc DDS clutch with Brembo hydraulics gives smooth yet reliable clutch control, while the 6-speed gearbox offers a wide range of ratios to tackle technical terrain and high-speed sections. Powerplant design also focuses on minimizing friction and centralizing mass — the engine is slightly tilted backward for a low center of gravity and better balance. For starting, the bike uses an electric starter powered by a lightweight 2 Ah lithium-ion battery. This setup ensures reliable starts and helps reduce overall weight. The wiring harness is smartly tucked under the seat to keep things clean and accessible. The chassis is built from 25CrMo4 chromoly steel in a double-cradle design, giving it the right mix of strength and flex for rugged terrain. The sub-frame is a two-part construction made from reinforced aluminum and polyamide, designed to flex under stress instead of breaking. To maintain stability, the Six Days has CNC-machined triple clamps and a forged steering head — these contribute to strong rigidity and precise handling, even at high speed or on demanding trails. Suspension is a standout: up front, there’s a 48 mm WP XACT upside-down fork with fully adjustable compression and rebound. At the back, a WP XPLOR PDS shock offers tool-free hand-adjustable dual compression clickers, making it easy to tune on the fly. Suspension travel is generous — 300 mm at the front and 310 mm at the rear — helping the bike soak up big hits, jumps, and rough terrain. The Six Days edition also comes fitted with GIANT alloy wheels (1.60×21″ front, 2.15×18″ rear) and high-traction Metzeler 6 Days Extreme tires, tailored for grippy performance in a variety of off-road conditions. Braking is handled by large discs — 260 mm at the front and 220 mm at the rear — providing reliable stopping power. In terms of ergonomics, the seat height is 963 mm, which suits taller or more experienced riders, and ground clearance is a generous 347 mm, helping clear obstacles easily. The fuel tank has a capacity of about 8.5 liters, made from transparent XPE material so you can easily see fuel level, and it’s designed for durability and low weight. KTM has also included modern rider aids: there’s a Map Select switch which lets riders toggle between different engine maps for varied terrain, and traction control (MTC) helps maintain grip when things get slippery. Optionally, there’s also a quick-shifter for clutchless upshifts (2nd to 6th gear), which is particularly useful for racing or long enduro stages. Durability is a big focus. The Six Days version includes factory protection like reinforced plastics, and the frame and subframe are built to resist stress and flex intelligently. The exhaust is compact and routed close to the engine for better mass centralization and protection. Overall, the KTM 350 EXC-F Six Days blends race-grade performance with thoughtful off-road capability. It’s a bike built for enduro warriors who want a powerful, agile, and durable machine — perfect for demanding multi-day events or serious trail riding. |
