| 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. | Heavy and bulky — its mass and size make it less agile for slow-speed manoeuvres, tight city traffic, or U-turns; handling can feel unwieldy compared to smaller bikes. Not ideal for daily commuting — in urban traffic, congestion, or frequent stop-and-go situations, its power and size become impractical; it isn’t a city-friendly ride. Economy and upkeep aren’t modest — fuel consumption, tyre wear, servicing, and maintenance costs tend to be higher than regular commuter bikes. Can be intimidating for newer riders — the bike demands respect: its power delivery, weight and overall presence might overwhelm someone without adequate riding experience. Limited practicality — storage space, comfort for pillion riding, and ease of everyday use are compromised compared to more utilitarian bikes; it’s more about thrill than convenience. |
| 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 Hayabusa feels like holding a full-blown super-sport bike in your hands — it’s serious, but not brutal. At its heart sits a 1,340 cc, 4-stroke, liquid-cooled, DOHC inline-four engine. With a bore/stroke of 81.0 mm × 65.0 mm and a relatively high compression ratio of 12.5:1, this engine isn’t about meek city-cruising — it’s about confident thrust. What that means when you twist the throttle: a surge of torque and power, even before you’re deep into the rev-range. The newer design — with lighter pistons, refined internals, improved lubrication passages, and a “Twin Swirl Combustion Chamber” — helps make the power smoother, more usable and reliable — not just explosive at high revs. On paper, power output is rated at 190 bhp at 9,700 rpm, with peak torque of 150 Nm at 7,000 rpm. What’s special is that this power and torque are tuned so the engine behaves well even in everyday riding — not just on open highways. The ride-by-wire throttle, a 6-speed constant mesh transmission and a wet, multi-plate slipper/assist clutch help make gear shifts smooth and predictable, whether you are crawling in traffic or throttle-on for a highway burst. You won’t miss performance on the open road — Hayabusa easily unleashes enough grunt to surge forward cleanly from mid-range, letting overtakes and roll-on acceleration happen without fuss. But thanks to the way Suzuki tuned the intake, combustion, and throttle control, it also avoids the jerkiness some high-power bikes suffer from — meaning daily commuting or city bursts become more manageable than a “raw” race-focused bike. Movement and posture on the Hayabusa reflect its dual nature: part super-sport beast, part (almost) grand tourer. Overall, the bike spans 2180 mm in length, 735 mm in width and 1165 mm in height, with a wheelbase of 1480 mm. A kerb weight of 266 kg and a seat height of 800 mm give it a substantial feel — you know you’re riding something serious. The fuel tank holds 20 litres, which on long rides gives you decent range. What that translates to in real life: on smooth roads and highways, the long wheelbase and weight lend the Hayabusa a stable, planted feel even at high speeds. On city roads, while it’s more weighty than a typical commuter bike, the slipper clutch, broad low-to-mid power band, and smooth throttle help manage manoeuvring and stop-and-go traffic without turning it into a monster. The suspension setup reflects a nice balance for a big sportbike: front uses inverted telescopic forks (oil-damped, coil spring), rear has a link-type single shock (coil spring, oil-damped) — both capable of absorbing road irregularities while giving predictable feedback. On an Indian road — where surfaces can vary — this setup helps smoothen things out, so you get a ride that’s firm enough for sporty riding but forgiving enough for real-world roads. Braking and tyres are equally serious. Up front there’s a twin-disc setup with top-tier Brembo Stylema® calipers, and a single-disc Nissin caliper at the rear. Both are ABS-equipped. The wheels wear tubeless tyres (front 120/70ZR17, rear 190/50ZR17) which together with the chassis and suspension offer strong grip and stability — important when you push hard, lean into curves or deal with unpredictable road surfaces. Where Hayabusa really steps ahead of “raw-power” bikes is its suite of electronics. The bike gets a comprehensive control package via its intelligent ride system: adjustable power modes (for sharp response or gentle city-friendly throttle), a bi-directional quick-shifter allowing clutchless up and down shifts, engine-brake control options, traction control that uses a 6-axis IMU to monitor lean/pitch/yaw (i.e. works even in corners), anti-lift (to prevent wheelies under heavy throttle), launch control, slope-dependent ABS, and more. In practical terms, this means that whether you’re “going fast” on a highway sweep, carving corners, or just commuting daily — the Hayabusa adapts. If roads are rough or conditions tricky, softer throttle maps and traction/ABS interventions give you confidence; if you want raw performance, the electronics let you tap it with assurance. It’s a surprising but welcome versatility — making Hayabusa less of a “race-only toy” and more of a real-world (albeit high-performance) bike you can live with. To sum up: riding Hayabusa feels like commanding a beast that knows how to behave. It has the grunt and top-end potential of a superbike, but thanks to Suzuki’s engineering — in engine design, chassis balancing, suspension tuning, braking, tyres and electronics — it’s also manageable enough for non-racetrack roads. On open highways you’ll feel its power truly — but even in city traffic or on back-roads, you won’t be fighting the bike; instead, you’ll be in control, enjoying its presence. |
