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. 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.
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 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.
