| 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. | Relatively heavy for a dual-sport / off-road bike: 177 kg kerb weight. Low-end torque is not very strong; engine feels dull at low RPMs. Rear shock only has rebound adjustment, no compression adjust — limits its tuning for aggressive off-road use. Kickstand safety switch design issue: possible accidental shutdown if kickstand is nudged. Some reports of stalling when using the quick-shifter, especially at lower revs. TFT screen is small and lacks some info (e.g. no fuel gauge, per reviews). High price: considered a bit premium for an “entry‑level” off-road-focused machine. |
| 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 390 Enduro R is KTM’s intention to build a true dual‑sport / light enduro motorcycle that blends its 390‑series performance with genuine off-road capability. Launched in India for around ₹ 3.36 lakh (ex-showroom), it’s positioned as a more rugged and off-road‑oriented alternative to the 390 Adventure, bringing serious trail-ready features in a relatively light package. At its core lies a 399 cc single‑cylinder, liquid-cooled LC4c engine, producing about 46 PS at 8,500 rpm and 39 Nm of torque at 6,500 rpm, according to KTM’s Indian spec. This engine is shared with the 390 Duke / Adventure, but in the Enduro R the tuning and gearing favor low‑to-mid range grunt — especially useful when riding off-road. Power is sent through a 6-speed gearbox with a mechanically operated slipper (or “assist/slipper”) clutch, giving it both durability and good control in uneven terrain. In terms of suspension, the India-spec Enduro R features WP APEX upside-down forks with 200 mm of travel up front, and a WP APEX split-piston shock at the rear with 205 mm of travel. While this is slightly less than the international spec, these settings are already tuned for a good balance of on-road stability and off-road absorption. The chassis uses a steel trellis frame and a die-cast aluminium swingarm, giving a rigid but relatively lightweight base to handle rough terrain with confidence. The Enduro R’s ergonomics clearly reflect its off-road wiring: it has a single-piece, flat, rally-style seat, allowing the rider to move position easily while standing or sitting. Bajaj Auto Its seat height is 860 mm, which is lower than many other dual-sport bikes, making it more accessible — especially for the Indian market. HT Auto It also offers a respectable ground clearance of 253 mm, helping clear obstacles and uneven terrain. HT Auto The bike rides on 21″ front and 18″ rear spoked wheels, fitted with Mitas Enduro Trail tyres for grip on unpaved surfaces. drivespark.com Braking is handled by disc brakes both front (285 mm) and rear (240 mm), and the bike comes equipped with dual-channel ABS that can be switched to an Off-road mode or even turned off at the rear for more controlled sliding. Bajaj Auto On the tech front, the 390 Enduro R doesn’t disappoint: it gets a 4.2″ anti-glare TFT display with Bluetooth connectivity, turn-by-turn navigation, music and call controls, and a USB-C charging port. Bajaj Auto There are two ride modes — Street and Off-road — which adjust throttle response and ABS settings. drivespark.com Traction control is also present, helping maintain grip on slippery off-road terrain. Bajaj Auto Fuel capacity is modest, with a 9-litre tank, which helps keep the weight down and the bike nimble. Bajaj Auto Speaking of weight, the kerb weight is 177 kg for the Indian spec, which is quite respectable given the off-road-ready components and protection gear. The Financial Express Overall, the KTM 390 Enduro R is a well-balanced machine that feels at home both on asphalt and dirt. It offers real off-road capability without compromising too much on daily usability. For those looking for a lightweight but powerful bike for trail riding, weekend adventure escapes, or even mixed commuting, this model is a compelling pick. Its feature-rich design and KTM’s proven engine make it a strong entry into serious dual-sport territory. |
