| Cons | High Maintenance: As a 2-stroke engine, it requires frequent servicing and tuning. Small Fuel Tank: Limited capacity means more frequent refills. Kick-Start Only: No electric start, which can be tricky for very young riders. Limited Power for Older Kids: The 50cc engine may not be enough as the rider grows or becomes more skilled. Sensitive to Tuning: Owners report issues like fouling spark plugs or needing to frequently re-jet the carb: “Used to run great … then started fowling plugs … Moved to a 95 main jet … About 15 kph slower …” Parts Cost & Availability: As a race‑oriented bike, some parts can be expensive or harder to source for older models. | Limited wind protection: As a naked bike, it has little windscreen; high-speed highway riding can be tiring due to windblast. Stiff suspension: The sporty suspension setup (especially the rear) can feel harsh on rough or uneven roads. Expensive maintenance: Some parts, accessories, and service intervals (especially major services) can be costly according to owners. Vibration at high revs: Some riders report vibrations and buzzing above certain RPMs, which affects mirror clarity and comfort. Fuel tank size: The 15-litre fuel tank is relatively small, which may limit range for longer touring or aggressive riding. Oil-check design: The use of a dipstick instead of a sight glass annoys some owners as it makes checking oil level less convenient. |
| Detailed Overview | The KTM 50 SX is a purpose-built mini motocross bike, tailored primarily for very young and beginner racers who want to get a genuine motocross experience without jumping straight to bigger bikes. It’s more than just a “toy” — KTM has packed serious race-bike DNA into this 50cc model, making it a standout choice for youth motocross training and competitive racing. At the heart of the 50 SX is a 49.9 cc single-cylinder 2-stroke engine, which delivers a punchy yet manageable power output. According to KTM’s specs, this engine is paired with a centrifugal automatic clutch, meaning there’s no manual clutch lever to worry about — the clutch engages automatically, which is ideal for young riders still building coordination and confidence. The engine uses a Seletra 2p D36 system for fuel delivery (on some models), which helps in precise tuning and reliable performance. KTM has thoughtfully designed the chassis for both strength and agility. The frame is made from chromoly steel, which keeps it light but sturdy. The overall design ensures that the bike is highly maneuverable, making it easier for young riders to learn balance and control on a real race-ready structure. The 50 SX isn’t just about motor and frame — it comes with serious suspension too: a WP XACT 35 mm upside-down fork at the front and a WP mono‑shock at the rear.The front suspension travel is around 200 mm and the rear is close to 190 mm, giving enough give for track bumps and jumps. In terms of ergonomics, the seat height is just 653 mm, making it very accessible for younger riders. Ground clearance is around 233 mm, giving the bike enough space to handle uneven terrain without scraping too much.The fuel tank capacity is modest — 2.3 liters — but that’s more than enough for short motocross sessions that young riders typically do. For braking, KTM hasn’t compromised: the 50 SX is equipped with disc brakes both front and rear, each 160 mm in size. This provides good stopping power and control, which is very important for safety and learning advanced braking techniques. On the wheels front, the bike uses spoke wheels, keeping things light and rugged for off-road racing. Despite its small size, the 50 SX is very race-focused. The frame has been redesigned to mimic the flex and rigidity characteristics of full-size MX bikes. The new frame also comes with frame protectors, which help reduce damage in case of falls — a common occurrence when young riders are learning. The handlebars are lightweight aluminum, with a bend that suits smaller riders, and the footpegs are designed to give a solid grip even when things get muddy or rough. KTM also includes power-reduction kits in its parts catalog for the 50 SX. These kits let parents or coaches limit the power output while the rider is still learning, which is a smart way to scale the bike’s performance to the rider’s ability — and once they’re better, the full power can be unlocked. When it comes to reliability, the 50 SX has a liquid cooling system for better thermal management. The engine’s central crankshaft design helps in keeping the mass well-balanced, which contributes to smoother handling. As for maintenance, like all 2-stroke motorcycles, it does need regular care — but KTM has made key parts (like the clutch) durable, using a reinforced clutch basket for longevity. Overall, the KTM 50 SX is a very well-engineered youth motocross bike that brings real race performance to younger riders. It balances power, weight, and control in a way that helps beginners grow into serious racers. Whether for track training, competitive racing, or just building early riding skills, it’s absolutely one of the top choices in the mini-moto world. | The Triumph Street Triple 765 RS is widely regarded as one of the most refined, sharp, and performance-focused middleweight naked sportbikes in the world, offering a thrilling combination of power, handling, and high-end equipment. At the heart of the motorcycle lies Triumph’s Moto2-derived 765 cc inline-three engine, which delivers explosive performance with a strong mid-range, razor-sharp throttle response, and an exhilarating top-end rush. Producing around 130 PS, the 765 RS is built to offer serious track-ready performance while remaining approachable for everyday road use. What truly sets the Street Triple 765 RS apart is its handling. The lightweight chassis paired with premium Showa Big Piston Forks at the front and an Öhlins STX40 monoshock at the rear ensures exceptionally precise cornering, excellent stability, and confidence-inspiring feedback. The bike feels fast, flickable, and agile, making it perfect for spirited mountain rides, urban commuting, and even full-fledged track days. Adding to its high-performance character are top-tier Brembo Stylema brakes, known for their sharp bite and excellent modulation. Triumph has equipped the RS with a comprehensive electronics package, including cornering ABS, cornering traction control, front wheel lift control, a bi-directional quickshifter, and multiple riding modes such as Road, Sport, Track, Rain, and Rider-configurable. These electronic aids are well-calibrated and enhance the riding experience without feeling intrusive. The 5-inch full-color TFT display adds a premium touch with its crisp graphics and intuitive layout. The RS also excels in terms of build quality, featuring a beautifully sculpted fuel tank, premium switchgear, and high-quality materials throughout. On the road, the Street Triple 765 RS strikes a fine balance between aggression and everyday usability. Its ergonomics lean towards sporty, with slightly committed handlebars and rear-set footpegs, but the riding position remains comfortable enough for medium distances and daily riding. Windblast, being a naked motorcycle, is noticeable at high speeds, but the bike’s lightweight feel and smooth power delivery make city riding surprisingly easy. Despite its many strengths, the 765 RS is not without drawbacks — the stiff suspension can feel harsh on poor road conditions, the fuel tank capacity limits long touring, and maintenance costs are relatively high due to its premium components. However, for riders seeking a motorcycle that blends top-tier performance with everyday practicality, the Street Triple 765 RS is one of the most rewarding and engaging options available. It offers an intoxicating mix of power, precision, and technology, making it a benchmark in the middleweight naked class and a favorite among enthusiasts who value speed, handling, and premium engineering in a compact yet powerful package. |
