| Cons | More expensive than many 125cc scooters, making it a premium purchase. Under-seat storage is smaller than what some rivals offer. Torque and overall performance may feel limited for riders who often travel with a pillion or heavy luggage. Suspension can feel slightly firm for some riders, especially on very bad roads. Service network and parts availability may not be as widespread as mass-market brands. | Tall Seat Height: At 825 mm, the seat may be uncomfortable or difficult to reach for shorter riders, especially off-road. Lack of Cornering ABS: Unlike the standard 390 Adventure, the X variant skips cornering ABS, which reduces safety margin when leaning hard. Limited Traction Control: Fewer electronic aids compared to higher-spec ADVs — could be less forgiving on unpredictable terrain. Vibrations at High RPMs: The single-cylinder engine can produce noticeable vibrations when pushed hard, affecting comfort. Moderate Wind Protection: The windscreen and fairing design might not deflect wind strongly enough at high speeds. Suspension Can Feel Harsh on Pavement: While great off-road, the long-travel suspension may feel firm or bouncy on uneven city roads. Maintenance Cost: Premium suspension components and tech might lead to higher service costs compared to simpler commuter bikes. Limited Pillion Comfort: The seat design and limited rear padding may not provide much comfort for a passenger over long distances. |
| Detailed Overview | The Aprilia SR GT 125 is one of those scooters that immediately feels different the moment you get on it. Instead of behaving like a typical city commuter, it carries the attitude of a lightweight adventure scooter, and that personality starts with its compact but sophisticated 125 cc i-get engine. This single-cylinder motor uses liquid cooling and a four-valve head, which means it breathes freely, runs cooler, and maintains performance even when the roads ahead are busy or slightly demanding. With around 15 horsepower produced at fairly high rpm, the scooter likes to be ridden with a bit of spirit. It doesn’t explode off the line, but it builds speed in a smooth, confident manner, especially when merging into faster traffic. The 12 Nm of torque comes in at mid-range, so in everyday riding the scooter feels responsive without needing to twist the throttle aggressively. Because it uses a CVT transmission, power delivery stays seamless. You just twist and go — making your way through city traffic without a second thought about gears. Even slow-speed maneuvering feels clean, thanks in part to the engine’s start-stop system, which cuts the engine at idle and brings it back to life the moment you twist the throttle. This not only saves fuel, but also makes the scooter feel lively and modern. Aprilia has built the SR GT 125 around a strong double-cradle steel frame, and that chassis gives it a planted feel on the road. Where many scooters tend to bounce or feel vague on broken surfaces, this one feels much more composed. The front end uses a 33 mm telescopic fork with generous travel, and the rear relies on twin shock absorbers with preload adjustment. Together, they soak up rough surfaces without making the rider feel disconnected. Riding over potholes or uneven patches doesn’t rattle the scooter; instead, it delivers a gentle, controlled movement that makes the overall ride surprisingly comfortable for something this sporty. Braking performance follows the same philosophy of confidence and control. Up front, there’s a large 260 mm disc, and the rear gets a 220 mm disc as well. Combined braking ensures that even less experienced riders get a balanced stop without grabbing too much front brake by mistake. In real-world use, the brakes feel progressive and strong — enough to inspire trust during sudden slow-downs, especially in crowded urban conditions. Dimensions also play a role in how this scooter behaves. Its wheelbase provides stability during faster stretches, yet the overall size keeps it agile in tight lanes. The seat height sits just under 800 mm, which means most riders can comfortably place a foot down at signals. The 9-litre fuel tank is larger than what most scooters offer, so you don’t need to refuel frequently — something daily commuters will appreciate. A big part of the SR GT 125’s personality comes from its tyres. With a 110/80-14 tyre at the front and a 130/70-13 at the rear, the scooter gets a slightly rugged stance while also benefiting from better grip and cornering feel. These wider tyres add stability when leaning through curves or navigating slippery monsoon roads. Alloy wheels help keep things light and responsive, making the scooter feel nimble without compromising ride comfort. On the features front, it includes fuel injection, an electric starter, and a modern instrument cluster that gives clear information without clutter. Everything is laid out to focus on real usability — nothing flashy for the sake of it, just features that make everyday ownership effortless. The seating is comfortable, the ergonomics encourage an upright, confident riding posture, and the overall build quality hints at durability. In real riding, the SR GT 125 feels like a scooter that wants to do a bit more than the typical city hop. It handles daily commutes with ease but doesn’t shy away from slightly longer rides or patchy roads. It’s the kind of machine that suits a rider who enjoys a little adventure in everyday life — someone who wants refinement, stability, and the feel of a well-engineered scooter rather than a basic runabout. It strikes a balance between practicality and fun, making it not just a commuter tool but a companion that engages the rider every time the road twists or roughens. | The KTM 390 Adventure X is a scaled-down, lightweight adventure motorcycle designed to give riders a taste of serious off-road experience without stepping into the realm of big-bore ADV bikes. Built to be agile yet capable, the 390 Adventure X combines rugged design, modern technology, and a peppy engine to deliver a balanced and versatile package. The motorcycle is powered by a 398 cc single-cylinder, liquid-cooled engine that makes about 46 PS and 39 Nm of torque, which gives it the right punch for both highway rides and trail days. One of the most appealing aspects of the Adventure X is its chassis and suspension setup. With WP APEX 43 mm USD front forks and a capable rear monoshock, the motorcycle offers good travel and suspension compliance. Its ground clearance of approximately 228 mm makes it suitable for mild to moderate off-road terrain, while its relatively light kerb weight improves maneuverability. Riders can confidently tackle gravel roads, broken trails or even slower forest paths, thanks to the suspension and lightweight design, making it a true entry-level adventure bike with real trail capability. KTM has equipped this motorcycle with modern electronics to back up its rugged design. A 5-inch TFT display serves as the cockpit, giving the rider access to useful ride data like gear position, speed, trip information, fuel, and more. The bike also supports Quickshifter+ for clutchless upshifts and downshifts in favorable conditions, enhancing the sporty feel. While the 390 Adventure X omits some high-end electronics like cornering ABS or full stability control, it includes switchable off-road ABS to allow controlled rear-wheel sliding for better off-trail control. Ergonomically, the Adventure X leans into KTM’s adventure-riding DNA with a tall seat, wide handlebars, and an upright riding position. This setup allows riders to stand comfortably on the footpegs—a critical feature when riding on uneven terrains. Despite its adventure-focused build, the 14.5-litre fuel tank gives it enough range for weekend touring or mixed terrain trips, particularly when coupled with the engine’s efficiency. In terms of design, the 390 Adventure X is rugged and purposeful. It features adventure-ready styling with skeletal fairing, broad fuel tank covers, an adjustable windscreen, and robust graphics that align with its off-road intentions. The slim bodywork and adventure-inspired elements give it an aesthetic that is as functional as it is stylish. While the 390 Adventure X is capable in a variety of conditions, it’s not without trade-offs. The tall seat height can be a hurdle for shorter riders, and the firm suspension may feel a bit harsh on smooth city roads. The lack of advanced rider aids like cornering ABS may deter some who ride aggressively on twisty roads. Vibration from the single-cylinder engine at high revs is also a possibility, especially when pushed hard. Despite these compromises, the KTM 390 Adventure X remains a compelling choice for riders who want real adventure capability in a manageable, lightweight frame. It’s ideal for new or intermediate dual-sport enthusiasts who want a rugged bike that excels off-road but doesn’t feel overkill on the pavement. With a strong balance of performance, technology, and capability, the 390 Adventure X reinforces KTM’s position in the adventure motorcycle segment by offering substance without overwhelming complexity. |
