| Cons | The Weight Is Impossible to Ignore – Parking, reversing, or making tight U-turns requires more effort than on most motorcycles. The bike feels considerably lighter once moving, but the weight is always present at low speeds. Not a Motorcycle That Enjoys Tight Corners – The Fat Boy is happiest on flowing roads. When the road becomes tight and twisty, its size and geometry become more noticeable. Wind Hits You Directly at Highway Speeds – Without a fairing or windscreen, long highway rides can become tiring because the rider takes the full force of the wind. Can Feel Warm in Traffic – Sitting in slow-moving traffic on a hot day makes the large V-twin's heat more noticeable around the legs. Passenger Comfort Is Average – The stock setup feels more focused on the rider. For frequent two-up riding, many owners look at accessory seats and backrests. Not Built Around Practicality – There is no meaningful storage space, and carrying luggage usually requires additional accessories. Running Costs Are Higher Than Average – Tyres, servicing, insurance, and genuine accessories can all add up compared to smaller motorcycles. Requires Some Experience to Get the Best Out of It – The combination of weight, engine size, and physical dimensions can feel intimidating for riders who are new to large-capacity cruisers. Floorboards Touch Down Earlier Than You Might Expect – Riders who push harder through corners will eventually find the limits of the cruiser-style setup. | Relatively heavy for a dual-sport / off-road bike: 177 kg kerb weight. Low-end torque is not very strong; engine feels dull at low RPMs. Rear shock only has rebound adjustment, no compression adjust limits its tuning for aggressive off-road use. Kickstand safety switch design issue: possible accidental shutdown if kickstand is nudged. Some reports of stalling when using the quick-shifter, especially at lower revs. TFT screen is small and lacks some info (e.g. no fuel gauge, per reviews). High price: considered a bit premium for an “entry‑level” off-road-focused machine. |
| Detailed Overview | Even among Harley-Davidson’s own motorcycles, the Fat Boy has always been difficult to mistake for anything else. The solid-disc Lakester wheels, broad fuel tank, chunky tyres, and low stance give it a silhouette that looks substantial from every angle. While many cruisers rely on chrome and visual complexity to create an impression, the Fat Boy’s design is built around simple, oversized elements that have remained part of its identity for decades. The motorcycle is based on Harley-Davidson’s Softail platform, which uses a hidden rear suspension arrangement beneath the seat area. From the side, the frame still resembles the rigid hardtail cruisers that inspired it, but underneath there is a modern monoshock setup responsible for absorbing road imperfections. The front suspension uses telescopic forks designed to support the motorcycle’s considerable weight while maintaining stability over varying road surfaces. A 1,923cc Milwaukee-Eight 117 V-twin engine sits prominently in the center of the motorcycle. Rather than encouraging riders to explore the upper reaches of the rev range, the engine develops much of its performance lower down, which influences how the Fat Boy behaves in everyday riding. The motorcycle can accelerate with relatively little throttle input, and the six-speed gearbox allows the engine to remain relaxed during highway travel. The large displacement and V-twin configuration are also major contributors to the motorcycle’s mechanical character and riding feel. Dimensionally, the Fat Boy is a substantial machine. Wide tyres at both ends, a long wheelbase, and a low seat height all contribute to its proportions. The low seating position places the rider close to the ground, while forward-mounted foot controls create the stretched riding posture commonly associated with large American cruisers. Combined with the wide handlebar, the rider’s position is very different from what would be experienced on a roadster or sport motorcycle. The Lakester wheels remain one of the defining visual features of the Fat Boy. Unlike conventional alloy wheels, their solid-disc-inspired design creates a unique appearance that has become closely associated with the model over the years. Alongside the broad tyres and muscular bodywork, these wheels play a significant role in shaping the motorcycle’s overall identity. Technology is present, although it is integrated more discreetly than on Harley-Davidson’s touring motorcycles. Modern versions include selectable riding modes, traction control, and ABS, with certain markets also receiving cornering-sensitive rider-assistance systems. Instead of a large touchscreen display, the Fat Boy uses a compact instrument setup focused primarily on essential riding information. An 18.9-litre fuel tank sits above the engine and forms one of the largest visual elements of the motorcycle. Lighting throughout the motorcycle uses LED technology, while the overall design remains intentionally uncluttered. There are few body panels, minimal visual distractions, and a clear emphasis on exposing the mechanical components that define the motorcycle. The Fat Boy’s specifications reveal a motorcycle shaped around traditional cruiser principles: a large-capacity V-twin engine, long-wheelbase chassis, low seating position, and substantial physical presence. Although modern electronics and engineering have been incorporated over time, the underlying layout remains closely tied to the formula that has defined the model for decades. | The KTM 390 Enduro R is a motorcycle designed mainly for riders who want to explore off-road terrain while still having the option to ride on regular roads. It sits somewhere between a proper dirt bike and a small adventure bike, but its overall design leans more toward off-road use. The bike has a tall stance, slim body, and minimal body panels, which help reduce weight and make it easier to move around on uneven surfaces. The riding position is upright, with a wide handlebar and narrow seat, allowing the rider to stand comfortably while riding on trails. It is powered by a 399cc single-cylinder, liquid-cooled engine that produces around 45 bhp. The engine feels smooth and predictable, which helps when riding on loose surfaces like mud, sand, or gravel. The power delivery is linear, so it does not feel too sudden or difficult to control. This makes it easier for riders to manage the bike in technical conditions, especially when traction is limited. The gearbox is well-spaced and works well in both low-speed trail riding and moderate road speeds. The suspension setup plays a big role in how the KTM 390 Enduro R performs. It comes with long-travel suspension at both ends, which helps absorb bumps, rocks, and uneven terrain. The bike also uses 21-inch front and 18-inch rear spoke wheels, which are commonly seen on off-road motorcycles. These larger wheels help the bike roll over obstacles more easily and provide better stability on rough surfaces. On paved roads, however, this setup can make the bike feel less sharp compared to road-focused motorcycles. When it comes to everyday usability, the KTM 390 Enduro R can be used in the city, but it comes with some compromises. The tall seat height can make it difficult for shorter riders to manage, especially in traffic. The seat itself is firm and narrow, which is helpful for off-road movement but not very comfortable for long rides. Wind protection is minimal, so riding at higher speeds for long durations can feel tiring. The fuel tank is also relatively small, which limits the overall range of the bike. In terms of features, the KTM 390 Enduro R includes modern electronics such as traction control, riding modes, and switchable ABS. These features help the rider adjust the bike based on different riding conditions, especially when switching between road and off-road use. The display is digital and provides basic riding information in a clear format. Overall, the KTM 390 Enduro R is built with a clear focus on off-road riding while still offering some level of road usability. Its design, engine, and suspension setup all reflect its purpose as a bike meant for trails and rough terrain rather than long-distance touring or daily commuting. |
| Expert Review | The Fat Boy has always been a motorcycle that prioritizes presence as much as performance. Even by cruiser standards, it feels substantial, whether you're looking at it parked or riding it down the road. The Milwaukee-Eight 117 engine suits the character of the bike perfectly, producing the kind of effortless torque that allows you to ride without constantly thinking about gear selection or engine speed. What stands out most is how planted the motorcycle feels once it's moving. The wide tyres, long wheelbase, and considerable weight create a sense of stability that encourages a relaxed riding style rather than an aggressive one. At the same time, those same traits mean the Fat Boy asks for a bit more effort in slow-speed situations and doesn't feel particularly eager when the road becomes tight and technical. The riding experience is less about chasing performance figures and more about the way the motorcycle delivers its power, carries its weight, and settles into a steady rhythm on open roads. Modern electronics have improved safety and usability, but they remain secondary to the traditional cruiser character that continues to define the Fat Boy., 4.4, MotoAutiv Team | The KTM 390 Enduro R is a dual-sport motorcycle that leans heavily toward off-road performance. It is powered by a 399cc single-cylinder engine that delivers smooth and linear power, making it manageable across both city roads and trails. The lightweight chassis, long-travel suspension, and 21/18-inch spoke wheels help it handle rough terrain with stability and control. On the road, it remains usable for short rides, but the tall stance, firm seat, and lack of wind protection make longer highway journeys less comfortable. The ergonomics are clearly designed for standing and moving during off-road riding rather than relaxed touring. Features like traction control, ride modes, and switchable ABS add modern functionality. Overall, it is focused more on off-road capability while still offering limited everyday usability., 4.3, MotoAutiv Team |
