| 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. | Single-seat limitation: It cannot carry a pillion, which might be a deal-breaker for riders who need two-up capability. Stiff rear suspension for some riders: On rough city roads, the suspension may feel firmer than expected, especially at lower speeds. Engine heat in traffic: The 334cc motor tends to generate noticeable heat during slow, bumper-to-bumper riding. Limited practicality: The bobber design restricts storage options, luggage mounting, and everyday utility compared to standard bikes. Smaller fuel tank: Longer highway rides may require more frequent fuel stops. Slightly heavy in tight spaces: While stable on the highway, its weight can be felt during U-turns or slow maneuvering. |
| 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. | Riding the Jawa 42 Bobber never quite feels ordinary — it’s a machine that makes a statement the moment you swing your leg over. The soul of this bike lies in its 334 cc single-cylinder, liquid-cooled, DOHC engine. That’s not just a handful of numbers — it’s a heart that delivers smooth throttle response, and more importantly, a strong mid-range punch. In day-to-day riding, whether you’re crawling through traffic or cruising on a highway, this engine delivers usable power without needing to be pushed hard. The 6-speed gearbox, paired with an assist-and-slipper clutch, makes gear changes feel refined. In the city, that helps — when you’re changing gears frequently, the clutch bite is lighter than on many cruiser-style bikes, but you still feel solid when opening up on open roads. The fuel injection system ensures consistent delivery of fuel, which helps with efficiency and makes sure power comes smoothly, with no surprise jerks or hesitation. On the road, the bike feels planted. Its low seat height — just 740 mm — makes it easy to touch the ground when stopped, which is a great confidence booster if you’re navigating crowded streets or tight parking situations. The wheelbase is long (1,485 mm), which helps stability when cruising, but the bike doesn’t feel cumbersome because its kerb weight (~185 kg) provides solidity without being overly heavy. The balance between comfort and control is nicely struck. Suspension is tuned just right for mixed urban and semi-highway conditions: telescopic front forks and a mono-shock with 7-step preload adjustment at the rear give you enough compliance for bumps, while remaining firm enough to feel stable through turns or during spirited rides. The preload adjustment is a thoughtful feature — if you occasionally carry a load or ride over rougher roads, you can tweak things to suit. Braking inspires confidence. With disc brakes on both front and rear, and dual-channel ABS, the Bobber gives you reliable stopping power. Whether you’re easing off at speed or needing to brake hard in sudden traffic, the system helps prevent wheel lock-up, which adds a layer of safety that’s especially helpful for less aggressive riders. Fuel tank capacity sits at 12.5 litres — not massive, but enough for a fair mix of city use and occasional weekend rides. You’ll want to plan fuel stops if you ride long distances, but for daily use it’s quite reasonable. Ergonomically, the Bobber leans into a relaxed cruiser stance. The forward-set footpegs, wide handlebars, and low seat invite a laid-back posture that’s ideal for relaxed rides, not aggressive sporty cornering. The single-seat layout reinforces that cruiser identity — it’s clearly made for solo riding, and not for pillion passengers. On the practical side, the 42 Bobber includes a modern digital instrument console, LED lighting, electric start, and useful indicators like low fuel. These touches bring a classic-looking bobber into the modern age without spoiling the minimal charm — you get just enough tech to feel contemporary, without unnecessary frills. If you ask whether this bike is for someone who just needs a daily commuter — it could be, but it truly shines when you treat it as a style cruiser. It’s less about beating traffic times or getting the most for every rupee of fuel, and more about enjoying the ride: the growl of its exhaust, the planted feel at speed, the freedom of minimal styling. For someone who values character, presence, and the feel of a modern classic, the Jawa 42 Bobber is a compelling pick. |
