Cons Not road legal and suitable only for off-road tracks. High maintenance due to 2-stroke engine rebuilds. Kick-start only, no electric start option. Relatively expensive compared to other youth dirt bikes. Small fuel tank limits long riding sessions. High Running & Maintenance Cost: Premium components (tires, brakes, consumables) and insurance can be expensive, as noted in reviews. Prone to Rear Tyre Wear: In aggressive use (especially on a track or spirited riding), the rear Michelin Power GP rubber may wear out quickly. Windblast & Comfort: As a naked “beast,” it offers limited wind protection, which can make highway riding tiring or uncomfortable. High Seat Height: The seat height (834 mm) may not be ideal for shorter riders. Electronics / Reliability Quirks: Some users have reported occasional electronic gremlins, sensor issues, or clutch drag. Expensive Purchase Price: Given the power and components, it comes with a high price tag compared to some rivals.
Detailed Overview The KTM 85 SX is one of the most popular and respected youth motocross bikes in the world, designed specifically for young riders who are ready to take the next big step toward competitive racing. More than just a beginner’s off-road bike, the 85 SX brings true race-bred DNA from KTM’s full-size SX lineup, giving upcoming racers the opportunity to experience high-level performance at an early age. With its sharp power delivery, lightweight design, and premium components, the bike is built to help young riders improve skills and confidently tackle motocross tracks. At the heart of the KTM 85 SX lies its 84.9cc 2-stroke, liquid-cooled engine, which is known for delivering punchy power and rapid acceleration. The powervalve system ensures that the engine produces strong torque across the rev range, making the bike easier to control while still offering impressive performance. Whether riders are attacking tight corners or hitting long straights, the engine responds crisply and delivers the thrilling character 2-strokes are known for. Paired with a 6-speed gearbox, the bike offers smooth shifting and plenty of flexibility for both beginners and experienced youth racers. One of the standout features of the 85 SX is its lightweight chassis, made with high-strength chromoly steel. This frame not only enhances stability but also ensures precise handling, allowing riders to maneuver confidently through jumps, whoops, and rough terrain. The ergonomics are thoughtfully designed to fit young riders, offering a slim body that allows easy movement, better grip, and improved control during aggressive riding. Suspension is another area where KTM excels, and the 85 SX is no exception. It comes equipped with WP XACT suspension, featuring an AER air fork at the front and a fully adjustable shock absorber at the rear. This setup provides excellent damping, great response on jumps, and impressive support on uneven surfaces. Riders can also fine-tune the suspension to match their weight, riding style, and track conditions — something rarely seen in youth motocross bikes. The bike also features powerful disc brakes on both ends, giving young riders the confidence to brake hard into corners. The wave-style discs help with heat dissipation, which is especially important during long practice sessions or competitive races. Lightweight wheels, grippy motocross tyres, and a race-focused design further enhance the overall performance package. In terms of ergonomics, the KTM 85 SX is designed to feel like a miniature version of the bigger SX bikes. The seat height, handlebar position, and narrow bodywork all work together to provide comfort while promoting proper riding posture. This allows young riders to develop good habits early in their riding journey. Overall, the KTM 85 SX is a bike built for serious young racers who want real performance, durability, and race-ready features. With its responsive engine, excellent suspension, strong brakes, and lightweight build, it stands out as one of the top choices in the youth motocross segment. Whether used for training or competition, the 85 SX gives riders a true taste of professional motocross performance. What stands out about the KTM 1390 Super Duke R is how everything on the bike seems to be built around performance rather than routine use, and that becomes clear once you look at the mechanical setup. It uses a 1350cc V-twin engine that produces close to 190 bhp and around 145 Nm of torque, paired with a 6-speed gearbox. The bike also gets a quickshifter and slipper clutch, which help in smoother gear changes, especially when riding at varying speeds. The throttle is controlled electronically through a ride-by-wire system, which manages how the engine responds to inputs. The frame is a steel trellis unit, designed to keep the bike rigid while also managing weight. The overall kerb weight is around 200 kg, and the fuel tank capacity is about 17.5 litres. The seat height is approximately 834 mm, which may feel slightly tall for some riders, particularly in slow-moving traffic. The riding position is slightly forward-leaning but still within the naked bike layout, with wide handlebars that offer leverage while turning. For suspension, the bike uses fully adjustable WP Apex components. At the front, there are upside-down forks, and at the rear, a monoshock setup is used. Both ends can be adjusted for preload, compression and rebound, allowing changes based on road conditions or riding style. The bike runs on alloy wheels fitted with wide tyres, which are designed to provide grip during acceleration and cornering. Braking is handled by twin discs at the front and a single disc at the rear. The system includes dual-channel ABS, along with features like cornering ABS and traction control, which help maintain stability when braking or riding on different surfaces. These systems work in the background and adjust based on the situation. The electronics package includes a TFT display that shows information such as speed, ride modes and system settings. It also supports features like cruise control and smartphone connectivity. The bike offers multiple riding modes, allowing changes in throttle response and electronic support systems depending on riding conditions. The overall design follows a sharp and aggressive naked bike style, with exposed elements and minimal bodywork. The tank, frame and panels are shaped to give the bike a compact but muscular appearance. Instead of trying to balance multiple roles, the setup stays focused on delivering a specific type of riding experience, which is reflected in both its design and mechanical layout.
Expert Review MotoAutiv Team In a market where most motorcycles are built around everyday needs, the KTM 1390 Super Duke R represents a very different approach to motorcycling in India. Its large-capacity engine and aggressive naked design are not shaped around daily commuting, especially in dense city traffic, but around performance and rider engagement. This makes it relevant to a smaller group of riders who are looking for more than basic transport and are interested in high-performance machines. Over time, factors like improving road infrastructure, growing track culture and increased awareness among buyers have created space for such motorcycles in the country. While its usage may be limited in typical conditions, it reflects how the Indian market is gradually opening up to motorcycles that prioritise performance and riding experience over everyday practicality., 4.6, MotoAutiv Team
