| Cons | Seat height is a bit tall, may be challenging for shorter riders to place feet flat at stops. Mileage tends to be modest (around 30–35 kmpl), especially if ridden hard not ideal for those seeking fuel economy. Fuel tank capacity is moderate may require frequent refuelling on long rides or at high speeds. You'll need regular maintenance (for twin-cylinder engine, etc.) more involved than simple commuter bikes. Riding posture and engine character lean sporty less relaxed comfort compared to cruiser-style bikes or scooters. Insurance, maintenance, and running costs will be higher compared to smaller, entry-level bikes. | High maintenance: being a 2-stroke race bike, it needs frequent servicing and top-end rebuilds. Costly parts: replacement parts (especially race-specific ones) can be expensive. Kick-start only — no electric starter, which may be difficult for smaller/younger riders. Limited fuel capacity: small fuel tank means more frequent refuels. Size limitations: while great for its class, more advanced or heavier riders may outgrow it soon. Not road legal — strictly made for off-road/motocross use. |
| Detailed Overview | The Aprilia RS 457 is a fully faired motorcycle built around a 457cc parallel-twin engine. This engine produces around 47 PS of power and 43.5 Nm of torque, and it uses liquid cooling to maintain stable temperatures during regular riding. The engine is paired with a 6-speed gearbox, and the overall power delivery is designed to be smooth and predictable, which helps riders manage it in both city and highway conditions. The bike also comes with ride-by-wire throttle, which allows different riding modes to adjust how the engine responds. In terms of design, the RS 457 follows a typical supersport layout with a full fairing, a sharp front section, and a slightly aggressive riding posture. The aluminium frame helps keep the overall weight low, with a kerb weight of around 175 kg. The fuel tank capacity is about 13 litres, which is practical for daily use as well as weekend rides. The seat height is around 800 mm, making it accessible for a wide range of riders, although the forward-leaning position may take some getting used to. The suspension setup includes upside-down front forks and a rear monoshock, both tuned to provide stability at higher speeds. The setup leans slightly towards the firmer side, which can make bumps and uneven roads more noticeable, especially on typical Indian road conditions. The braking system includes a front disc and a rear disc, supported by dual-channel ABS, which helps maintain control during braking. The bike also uses wide radial tyres that offer grip in different riding situations. The Aprilia RS 457 comes with a modern electronics package that includes traction control and multiple riding modes. These features adjust parameters like throttle response to suit different riding conditions. All important information is displayed on a digital TFT screen, which shows speed, gear position, fuel level, and other details in a clear format. Some variants also offer a quickshifter as an option, allowing clutchless gear changes. The riding position is slightly committed, with clip-on handlebars and rear-set foot pegs, which gives it a sporty feel. At the same time, the overall size and weight make it manageable compared to larger supersport bikes. The bike is designed to offer a balance between performance and everyday usability, although factors like traffic conditions, road quality, and riding style will influence how it feels in regular use in India. | The KTM 65 SX is one of the most iconic and trusted youth motocross bikes in the world, built for young riders who are ready to step into competitive racing. Designed as a bridge between mini dirt bikes and full-size motocross machines, the 65 SX gives young racers the taste of real racing performance with features inspired directly from KTM’s bigger SX lineup. For many aspiring riders, this bike marks the beginning of a serious motocross journey. At the core of the KTM 65 SX is its 64.9 cc 2-stroke, liquid-cooled engine, designed to deliver smooth yet powerful performance. The engine is known for its sharp throttle response and punchy powerband, which helps riders tackle jumps, corners, and straights with ease. With its race-tuned powervalve system, the bike offers strong torque and acceleration across the rev range, making it highly competitive on the track. The 6-speed gearbox paired with a hydraulic clutch further enhances control, allowing young riders to shift smoothly and confidently during intense racing situations. One of the major highlights of the 65 SX is its lightweight chassis, which gives the bike excellent agility. Weighing just around 53 kg, it allows young riders to maneuver easily, even in technical sections. The frame is built using high-strength chromoly steel, offering a perfect balance of rigidity and flexibility. This helps maintain stability during high-speed riding while still giving enough flex to absorb rough terrain. Suspension plays a huge role in motocross, and KTM has equipped the 65 SX with premium WP XACT suspension. At the front, it features a 35 mm AER air fork, which allows easy adjustment based on the rider’s weight and riding conditions. At the rear, a fully adjustable WP monoshock ensures consistent damping performance. This suspension setup works beautifully on jumps, whoops, and rutted tracks, making the bike feel planted and confidence-inspiring. Braking is equally impressive, with hydraulic disc brakes on both ends providing sharp stopping power. This is especially important for young racers learning advanced braking techniques such as trail braking and hard corner entries. The wave-style discs also help manage heat buildup during longer motos. The ergonomics of the KTM 65 SX are carefully designed to suit growing riders. The seat height, footpegs, and handlebar position give young riders a natural and balanced stance, allowing them to ride longer with less fatigue. The slim bodywork also makes it easier for riders to shift their weight when cornering or navigating obstacles. Another advantage is its “grow-with-the-rider” setup. Many components, including the handlebar and suspension, can be adjusted, making the bike suitable for a range of ages and sizes. This is one of the reasons why parents and young racers prefer the 65 SX — it adapts as the rider’s skills and physical size improve. Overall, the KTM 65 SX is a race-ready machine built to deliver high performance, reliability, and confidence to young riders entering the world of competitive motocross. With its strong engine, agile handling, premium suspension, and race-focused design, it remains one of the best choices for aspiring motocross champions. |
| Expert Review | The Aprilia RS 457 fits into the entry-level performance segment in India, where many riders are moving from smaller bikes to higher capacity machines. Its 457cc twin-cylinder engine feels smooth and manageable, but in daily city traffic, the riding posture and heat can still be noticeable. The suspension and chassis are set up for sporty riding, which means rough roads may feel slightly uncomfortable. It also comes with modern electronics that may take some time for new riders to fully understand. The service network is still growing, which can affect ownership experience in some cities. It is more suited for riders looking for performance-oriented riding rather than regular commuting., 4.1, MotoAutiv Team | MotoAutiv Team |
