| Cons | The seat is firm and compact, which can feel less comfortable on longer rides or with a pillion. The suspension is firm, so rough or pothole-laden roads transmit more bumps to the rider. Fuel tank capacity is modest at 6.5 litres, limiting range for longer trips. Storage space is limited, restricting the ability to carry larger items or full-face helmets comfortably. Being a smaller-displacement scooter, highway cruising is limited, and top speeds are moderate. | High Power-to-Weight Ratio: The 249.9 cc 4-stroke engine produces very strong power, and the bike is quite light — making it very agile and fast. Advanced Electronics: Comes with launch control, two engine maps, traction control, and quickshifter — very race-oriented features. Premium Suspension: Uses WP XACT forks and rear shock (310 mm / 300 mm travel) that are very capable for jumps and rough track terrain. Excellent Chassis Flex & Control: Updated frame in newer models improves flex, which helps in cornering and gives more control. Electric Start: Equipped with a self-starter (lithium-ion battery), which is very handy on the track. Strong Brakes & Clutch: Uses Brembo hydraulics for the clutch and good brake setup — helps with precise control under race conditions. Good for Track Riders: Designed for serious motocross use — responsive, fast, and optimized for racing-style riding. |
| Detailed Overview | Riding the Aprilia SR Storm 125 gives you a sense of having a sporty, nimble scooter beneath you — its heart is a 124.49 cc, air‑cooled, single‑cylinder engine with a 3‑valve head and fuel injection. That sounds modest, but in the context of urban and everyday commuting it’s tuned to deliver consistent, usable performance. With about 9.92 PS of power at 7,700 rpm and 9.7 Nm of torque at 6,000 rpm, the Storm 125 doesn’t offer wild acceleration, but it provides smooth, predictable acceleration that’s more than enough to dart through city traffic or handle daily errands without fuss. The automatic CVT + belt‑drive means you don’t need to worry about shifting — just twist and go, which is ideal for traffic, frequent stops or unpredictable stop‑and‑go conditions. Underneath, the Storm rides on a tubular steel frame, supported up front by a telescopic fork (with a 30 mm inner tube) and at the rear by a mono‑shock absorber. The wheels are 12‑inch alloys, wrapped with tubeless tyres — 120/80‑12 at the front and 130/80‑12 at the rear. That combination gives the scooter a compact footprint, making it easier to weave through traffic or negotiate narrow lanes. The smaller wheels and higher‑profile tyres help soften the ride over potholes or rough stretches compared with low‑profile tyres: while it won’t ride like a large cruiser, the Storm feels more forgiving over broken or uneven roads than a typical performance‑oriented small scooter might. Braking is handled via a 220 mm disc at the front and a 140 mm drum at the rear, with a Combined Braking System (CBS) to help distribute braking force — which means braking is stable and weighted rather than sudden, useful in city conditions or when a quick stop is needed. That front disc gives enough bite for confident stopping without fuss. In terms of size, the Storm stretches about 1,985 mm in length, with a wheelbase of 1,365 mm — compact enough to feel agile but long enough to give reasonable stability. Seat height sits at about 780 mm, which tends to be manageable for most riders, making stops or mounting/dismounting easier in day‑to‑day use. The kerb weight is roughly 118 kg: light enough to manoeuvre easily in tight traffic, yet with enough heft to stay planted at moderate speeds or on uneven surfaces. A 6.5‑litre fuel tank sits under the fuel cap. That size isn’t huge, but paired with the modest engine and decent fuel efficiency (official figures suggest around 38–40 km/l — real‑world numbers will vary with riding style), it offers a practical range for daily commuting, errands, or short-to-medium rides before needing a refill. On the features front, Storm 125 doesn’t try to be flashy — it keeps things practical. You get a simple analogue + digital instrument cluster that shows speed, fuel level, trip info, etc. The headlight and tail/indicator lighting are LED (or partially LED, depending on the variant), which helps with visibility. There’s under‑seat storage, a passenger footrest, a low‑fuel warning lamp, and a USB charging port in some variants — helpful touches if you use the scooter for errands, short trips, or commuting with a phone/GPS in tow. Starting is achieved via kick as well as electric self‑start — handy for reliability or if the battery is low. What this all adds up to in real life is a scooter that’s built to be practical, economical, and easy to live with — but with a twist of sportiness and style. The Storm 125 doesn’t try to pretend it’s a high‑power motorcycle; rather, it leans into being a user-friendly, agile, and fairly efficient daily rider with a more aggressive look and feel than a basic commuter. It is especially suited for those who navigate busy city streets, need easy parking and manoeuvrability, and want a scooter that’s simple to ride, easy to maintain, and functional for everyday needs — but with a bit more character than a plain‑Jane scooter. | The KTM 250 SX‑F is a purpose-built motocross machine that combines race-ready performance, lightweight agility, and advanced electronics to deliver an exhilarating experience for serious off-road riders. As part of KTM’s renowned motocross lineup, the 250 SX‑F is designed for track dominance, providing the perfect balance of power, handling, and precision for competitive riding. Its 249.9 cc, four-stroke, single-cylinder, liquid-cooled engine is tuned to deliver strong, high-revving power that is immediately responsive to throttle inputs. This makes it exceptionally capable on tight corners, jumps, and technical track sections, giving riders a confident and aggressive edge in race situations. One of the standout features of the 250 SX‑F is its lightweight chassis. The bike benefits from KTM’s proprietary trellis frame, which offers a perfect blend of stiffness and controlled flex. This results in excellent stability at high speeds while also allowing precise feedback through the handlebars and footpegs. The frame’s low weight, combined with the compact engine, ensures the bike is agile and easy to maneuver—qualities that are especially important when navigating tight motocross tracks or technical off-road terrain. The overall kerb weight remains impressively low, which reduces rider fatigue and enhances the bike’s responsiveness. The 250 SX‑F’s suspension system is another highlight. It features WP XACT 48 mm inverted front forks and a WP XACT rear shock with linkage, delivering around 310 mm of front travel and 300 mm of rear travel. This setup allows the bike to absorb big jumps, handle rough terrain, and maintain traction even under extreme stress. Both the forks and the rear shock are fully adjustable, enabling riders to fine-tune the bike for their preferred riding style or track conditions. The combination of suspension, frame geometry, and lightweight design makes the KTM 250 SX‑F exceptionally capable at both high-speed sections and technical, slower parts of the track. Modern electronics further enhance the riding experience. The 250 SX‑F is equipped with launch control, which optimizes starts and reduces wheel spin. Additionally, it offers selectable engine maps and traction control, providing riders with the ability to adapt the bike’s power delivery to track conditions or personal preference. The inclusion of a quickshifter enables seamless clutchless gear changes, maintaining momentum during aggressive racing. While minimal compared to street motorcycles, these electronic aids give riders an advantage without sacrificing the raw, track-focused feel that motocross enthusiasts demand. The ergonomics of the 250 SX‑F are designed with performance in mind. A tall seat height, wide handlebars, and a compact, upright riding position make it ideal for both sitting and standing on the pegs, which is essential for maneuvering over rough terrain and jumps. The bike also features an electric start, a convenience that eliminates the need for kick-starting and enhances usability on the track. Despite its racing pedigree, the 250 SX‑F comes with some compromises. Its fuel tank is relatively small, limiting the bike’s range to short race sessions rather than long trail rides. Maintenance is more frequent compared to casual dirt bikes, as high-performance components require careful attention. The tall seat height may also challenge shorter riders, and its race-oriented suspension can feel harsh on less demanding trails. In summary, the KTM 250 SX‑F is a high-performance motocross machine designed for riders who demand precision, agility, and race-ready power. Lightweight, technologically advanced, and built with competition in mind, it offers an exhilarating experience for those seeking to dominate motocross tracks. It is not a casual trail bike, but for dedicated racers and serious off-road enthusiasts, it stands out as one of the most capable and exciting 250-class motocross motorcycles on the market. |
