Detailed Overview Riding the Jawa 42 FJ feels like you’re commanding a machine that strikes a rare balance — it’s rugged without being raw, modern without giving up its classic soul. Under its skin lives a 334 cc, single-cylinder, liquid-cooled DOHC engine that’s tuned to generate about 29.17 PS of power and 29.62 Nm of torque. That power figure isn’t about wild acceleration; it’s about usable, confident torque right in the midrange — the kind that lets you surge past slow-moving traffic or carry speed comfortably once you’re out on open roads. Because the engine is liquid-cooled, it resists overheating even in stop-go traffic or during longer rides, which is a big plus for both city commuters and weekend travellers. Paired with that engine is a 6-speed constant-mesh gearbox, which gives the 42 FJ a flexibility that many retro-inspired bikes lack. In the city, lower gears help you navigate tight turns and slow zones; crank into the higher gears on the highway, and the bike relaxes into a smooth, sustained rhythm — it doesn’t feel stressed or out of breath. The assist-and-slipper clutch makes downshifts lighter and safer, especially when you’re slowing down hard or tackling steep terrain. This kind of setup means you don’t have to wrestle with clutch levers constantly — the bike does a lot of the work for you. On the road, the frame’s double-cradle design gives the bike a stable backbone. The front suspension is handled by telescopic forks (41 mm), while the rear uses twin shock absorbers with 5-step preload adjustment. In real-world terms, that means potholes and rough patches don’t slam into your spine — there’s just enough give to absorb most imperfections without turning the ride into a mushy mess. Once the road smooths out, the brakes — dual disc with floating calipers and dual-channel ABS — give strong, predictable bite. You feel secure braking hard, even when you’re leaning into a turn or coming down from highway speed. The motorcycle’s dimensions also contribute to its confidence-in-motion: a wheelbase of 1,440 mm gives it stability, while a seat height of 790 mm makes it accessible for many riders without feeling too compact. Ground clearance sits at 178 mm, which helps when you’re navigating over uneven terrain or clearing speed breakers — something very relevant in real-world road conditions. At a kerb weight of around 184 kg, it’s not feather-light, but once moving, it feels planted rather than ponderous. In city traffic, the weight is manageable; on highways, it adds to the sense that the bike is confident and steady. Fueling comes from injection, and though the claimed tank capacity is 12 litres, the real-world balance likely leans toward practicality over long-range touring. For regular commuting and moderate weekend rides, that tank paired with the efficient engine should work well, though it may not give you motorway-range without a stop. Riders who expect to do long-haul touring might need to plan fuel stops more carefully. The wheels are wrapped in road-friendly tyres (100/90-18 up front, 140/70-17 at the rear), which, along with the disc-brake setup, reinforce good grip and handling. The brakes feel responsive — not grabby, but confident. That’s exactly what you want when your speed is building or when traffic messes up your smooth ride. Electronics on the 42 FJ are minimal but practical: there’s a fully digital instrument cluster that shows speed, gear position, fuel, and trip details — all clearly visible so you don’t have to squint or guess. No flashy connectivity gimmicks, but the essentials are covered well. The exhaust comes in a twin layout, which gives the FJ a good exhaust note — neither too loud to be annoying in residential areas, nor too soft to sound uninspiring. In terms of design, the 42 FJ stands out. The brushed aluminium cladding on the tank gives it a distinctive, premium look. It’s not just retro for retro’s sake — the styling feels purposeful, with a bold, modern twist. Colours range from deep matte shades to dual-tone finishes, giving riders a variety of looks to express themselves. Price-wise, the ex-showroom figure starts at around ₹1.93 lakhs and can go to about ₹2.2 lakhs depending on variant and location. Riding one means committing to a machine that’s not just about show: you’re getting a bike with real substance — capable of daily commuting, capable of enjoyable weekend rides, and capable of delivering a retro-modern experience without too many compromises. Overall, the Jawa 42 FJ feels like a well-rounded partner on two wheels. It doesn’t demand constant attention or aggressive riding, but it rewards smooth, thoughtful throttle control and confident road use. For someone looking for a neo-classic bike that’s equally at home in city traffic and on open highways, it’s a choice that marries character with practicality. 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.
