| 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. | The KTM 1390 Super Duke R is the ultimate expression of KTM’s “Beast” philosophy — a high-performance naked streetfighter that pairs brutal V-twin power with razor-sharp handling and modern electronics. At its core is a 1,350 cc LC8 V-twin engine that churns out around **190 PS (approximately 188–190 bhp)** at 10,000 rpm and **145 Nm of torque** at 8,000 rpm, giving it an immense punch and a visceral, muscular character. The engine also makes use of a cam-shift (variable valve timing) system that enhances its performance spread, delivering strong torque low down and explosive power at high revs. Built on a chromium-molybdenum steel trellis frame, the 1390 Super Duke R is not only powerful but also impressively agile for its size. KTM pairs the frame with high-quality WP APEX suspension — a 48 mm USD front fork and a linkage monoshock at the back — to strike a balance between compliant ride quality and sporty precision. ([KTM][1]) Cornering ABS by Bosch, traction control (MTC), a slipper clutch, and a five-mode ride-mode system (Street, Sport, Rain, Track, Performance) give the rider confidence to explore the bike’s full potential. Braking is handled by forceful Brembo Stylema calipers (320 mm twin discs at the front, 240 mm at the rear), ensuring the Super Duke R can back up its power with excellent stopping authority. Visually, the Super Duke R is bold, aggressive, and unmistakable. The angular bodywork, sharp LED headlight with characteristic DRLs, new tank shrouds, and subtle winglets give it a predatory look that lives up to its nickname. The trellis frame is painted in KTM’s signature orange, providing both structural strength and stylistic flair, while the narrow tail section completes the streetfighter stance. Technology is a major strength. Its 5-inch TFT display is loaded with KTMConnect for smartphone pairing, and in Track mode it shows telemetry data such as lean angle, lap times, and G-forces. ([Bajaj Auto][3]) The electronics suite also includes wheelie control, launch control, anti-slide, and a quickshifter for seamless clutchless upshifts and downshifts, adding to the bike’s performance-focused edge. KTM even brings a “Demo Mode” for a limited period — allowing riders to try out all electronic aids in the first 1,500 km before choosing what to permanently enable. In terms of practicality, the Super Duke R is surprisingly usable on the street. Its seat height of **834 mm** and a kerb weight of about **200.5 kg** make it relatively manageable compared to more extreme superbikes. The fuel tank is 17.5 litres, offering a decent range for a performance beast. Despite its aggressive nature, it can be tuned via its various ride modes for more relaxed everyday use — though wind protection is limited due to its naked-bike design, and long highway stints may feel less comfortable than on touring bikes. In the Indian market, KTM prices the 1390 Super Duke R at ₹ 22.96 lakh (ex-showroom), positioning it as a flagship naked bike with no shortage of performance or tech. However, its premium components and high-performance nature come at a cost: maintenance, tyres (Michelin Power GP), and high-spec brakes are all expensive, and potential buyers should be prepared for that. Overall, the KTM 1390 Super Duke R is not for the faint of heart — it’s a powerful, aggressive, and technically sophisticated machine built for riders who demand extreme performance, advanced electronics, and a visceral riding experience. For enthusiasts looking for a street-focused beast that delivers both in city traffic and on twisty roads, it stands out as one of the most capable and exhilarating naked bikes on the market today. |
