Kawasaki Z650

There’s something undeniably appealing about the idea of a middleweight naked that manages to balance approachability, versatility, and real-world thrills. The Kawasaki Z650 has, over the years, found its own set of loyalists precisely because it makes stepping into the big bike league seem less intimidating. I’ve spent some meaningful time with the latest generation Z650 BS6, and what stands out right away is its intent to inject a bit more premium flavor without losing the qualities that made it such a favorite among riders breaking into the 650cc club for the first time. But the real question is, with a raft of updates like the LED headlights and a snazzy TFT dash, does the new Z650 finally feel as “big bike” as its price tag suggests, or does it still miss the mark on desirability? Let’s dive deep.

The Z650 now wears Kawasaki’s “Sugomi” design philosophy. If you’ve gotten a glimpse of its siblings, the Z400, Z900, or the intimidating Z1000, you’ll spot the similarities right away. This update dresses the Z650 with sharper, more assertive lines. The newly sculpted headlamp is blatantly aggressive, complemented by tank extensions and a set of darkened tail lamp accents that add an extra hint of menace. 

The Kawasaki Z650 is offered in just one colour option: Metallic Matte Dark Gray / Metallic Spark Black. This focused choice means you won’t be overwhelmed by multiple shades or confused over what suits you best.  

The Kawasaki Z650 rides on five-spoke alloy wheels with a webby, star-like pattern. The spokes themselves look surprisingly slim compared to the norm, but if Kawasaki thinks they suit this high-performance machine, we have no reason to doubt it. There’s also subtle red pinstriping on just under half of the wheel rim, adding a faint touch of red to the otherwise almost all-black bike. 

I’ve always appreciated the way Kawasaki handles fit and finish, and the Z650 is no different. The panel gaps are consistent and tight, lending the bike a genuinely upmarket aura. The switchgear, while robust and tactile, is beginning to show its age from a design standpoint. Yet operating them, with their satisfying clicks and solid resistance, gives that low-key pleasure which only well-crafted controls can provide. Overall, the Z650 feels far more premium than earlier iterations, a shift that’ll be appreciated by riders who demand more than just spec-sheet value.

The headlight update deserves a mention. Now running a full-LED cluster up front, the Z650 sheds its dated halogen bulbs for something brighter, whiter, and, importantly for Indian monsoon nights, more focused. It’s genuinely impressive how much of a difference a properly-engineered LED unit can make in everyday safety, especially during late commutes or when rain turns city roads slick and unpredictable. Out back, the Z-shaped LED tail-light is an eye-catcher both for its looks and for the visibility it offers other road users.

Curiously, the bike skips LED turn indicators, retaining the somewhat chunky bulb units. When models in lower segments are already offering complete LED packages, this omission feels odd, a minor blemish on an otherwise well-kitted-out feature list. Kawasaki sticks to its ethos of “less is more” when it comes to electronic rider aids. On paper, that keeps the ride pure. In practice, apart from ABS, don’t expect a variety of riding modes or traction control.

The previous Z generations slightly shortchanged owners when it came to modern instrumentation. That’s changed. The new Z650 wields a 4.3-inch colour TFT dash, a marked leap upward from the digital LCD console it replaces. The interface feels modern, crisp, and, most importantly, legible even on blinding summer afternoons. The absence of customisable layouts is more than compensated by the dash’s clarity and font size. It also brings Bluetooth connectivity into play using Kawasaki’s Rideology app, for logging rides, call notifications, and even parked bike location. However, there are pain points: all interactions with the menu are clunky, requiring use of two buttons beneath the screen. After using premium switchgear controls on rivals, it feels clumsy and slow. More annoyingly, the Rideology app fails to offer real-time call or SMS pop-ups on the console, nor does it allow riding navigation.

For me, comfort begins at the saddle, and the Z650 doesn’t disappoint, within reason. The 790mm seat height is welcoming for riders of even my modest height of 5.5 feet, making it easy to get both feet on the ground at stops. Once on the seat, the bike’s ergonomics settle you into an upright but slightly forward-biased posture, striking a great balance between aggression and comfort, whether in city traffic or on a winding highway. The tank cutouts are generous, offering solid support for your knees during spirited rides. 

The pillion saddle is a mixed bag. While space is adequate for casual city runs, the stiff rear suspension means that your passenger will feel every sharp pothole and bump, sometimes with more intensity than the rider. Over longer journeys or less-than-smooth surfaces, expect your pillion to voice some complaints. 

Beneath all the visual drama is a 649cc, liquid-cooled, parallel-twin engine. Kawasaki’s work to make it BS6 compliant comes with little penalty: maximum power remains unchanged, though peak torque dips slightly (down by 1.7Nm). With the weight nudging up by a mere kilogram, performance figures on paper take a small hit. But in reality? There’s barely a hint of it. The Z650’s engine feels utterly tractable, pulling cleanly from as low as 2,000rpm, with a build-up that becomes positively urgent around 3,500 to 6,500rpm—precisely where urban riding and Indian highways demand their punch.

In city conditions, the engine’s refinement impresses. Traffic gaps disappear with a lazy twist of the throttle. The clutch is light, thanks to the slip-and-assist mechanism, and low-speed tractability means you’ll seldom need to hunt for first gear. However, this is a parallel twin that likes to express itself: twist hard, and the raspy intake, joined by a throatier exhaust note, gives the Z650 a character that’s much livelier than you’d expect for a middleweight. Heat management is good, with engine warmth evident but never reaching the point of discomfort, barring Pune’s notorious summer traffic jams.

Take the Z650 out on the highway, though, and it comes alive. The engine settles into an easy ride at 120kmph, with enough punch in reserve for quick overtakes. Cruising at these speeds is a delight, and that 10,000rpm redline feels far off, even as you wind it up for rapid progress. Long stints don’t feel stressful, and overtaking slow-moving vehicles rarely demands a downshift—just a little wrist action is all it takes.

The six-speed gearbox deserves some scrutiny. Shifts are positive and precise, satisfying in their mechanical engagement, but there’s no denying a certain clunkiness that has crept in compared to older versions. While this doesn’t ruin the riding experience, riders used to ultra-slick shifting bikes may feel a twinge of disappointment during stop-start traffic or hurried downshifts.

On the open road, fuel efficiency improves considerably. Coupled with the generous 15-litre tank, real-world range is more than 300km between fills—a solid number for touring. For city-only riders, expect that number to dip, but not dramatically so. That’s a testament to Kawasaki’s clever engineering: you get usable power without severely compromising mileage or refinement at a cruise.

Kawasaki retains the trustworthy steel trellis frame for the Z650, mated to 41mm telescopic front forks (125mm travel) and a preload-adjustable monoshock at the rear (130mm travel). On paper, it’s not a revolutionary setup, but the tuning makes all the difference.

Braking comes courtesy of twin 300mm petal discs up front and a 220mm rear disc. On paper, this should translate to stopping power you can bank on. In the real world, while the hardware is robust, the over-intrusive ABS does rear its head a little too quickly, especially during hard stops. The feeling is that of being gently pushed forward, rather than coming to a determined standstill. Much of this comes down to the choice of Dunlop Sportmax Roadsport 2 radials, which our test unit came with too. They provide adequate grip in the dry but feel less secure on wet or slick surfaces. For riders prioritizing braking performance, a swap to stickier rubber will be transformative.

Despite its 191kg kerb weight, the Z650 is easy to ride through city traffic. The leverage offered by the wide bar and the quick steering combine to make the bike feel much smaller and lighter than it actually is. Parking lot maneuvers, U-turns, and filter lane sprints become second nature in no time.

Highway behavior is reassuring. The long wheelbase and sorted weight distribution mean directional stability is excellent. At speed, the bike never feels skittish or nervous, and even windy days fail to unsettle it.

For newer riders, the willingness with which the Z650 tips into a corner is genuinely confidence-inspiring. Despite the stiffer ride, it feels poised and planted when leaned over—at least until the road turns damp or polished, where the tyres quickly reveal their limits. Seasoned riders will find room for improvement here but, straight out of the showroom, it is a competent, fun handling package.

Where the old BS4 Z650 offered a more forgiving ride, the new bike stiffens up its resolve. At low speeds, every sharp bump, pothole, and expansion joint communicates itself up the spine, especially to lighter riders. On less-than-perfect urban roads, you’re always conscious of the bike’s firmer damping, and if you habitually ride with a pillion, expect a few complaints from the back seat.

There’s some relief when you carry speed. Out on the highway, the Z650’s suspension feels more settled, absorbing undulations better at pace. Still, I found myself reaching for the rear preload adjuster (not the easiest to access, mind you) in pursuit of a plusher ride. Those who regularly traverse patchy city roads may find it worthwhile to dial back on preload, even if it requires minor disassembly.

It’s easy to see why the Z650 commands such loyalty among the middleweight naked crowd. The latest round of updates catapults its premium feel, thanks to features like the TFT dash, LED lighting, and a more engaging exhaust note. The bike is comfortable, reasonably fast, and friendly—without intimidating newer big bike riders. It’s not a showstopper in any single area, but it’s the sum of these carefully considered parts that makes the Z650 such a complete motorcycling experience. The ride is now stiffer, which will irk some, but you trade off that comfort for a sharper, more rewarding dynamic package. The only thing missing is a real sense of excitement from the engine, and some electronic aids would be nice given today’s competition.

The Kawasaki Z650 sits in a competitive middleweight naked segment, facing stiff competition from motorcycles like the Honda CB750 Hornet, and Triumph Trident 660. Each rival brings something unique. The Honda CB750 Hornet blends aggressive styling with a potent 755cc engine, aiming for riders who want a sporty naked with modern performance. The Triumph Trident 660 impresses with its premium build, triple-cylinder engine character, and sophisticated tech, positioning itself as the more refined but pricier option. Compared to these, the Z650 stakes its claim through a strong balance of approachable power, sharp Sugomi design, and a no-nonsense feature set, making it a solid all-rounder for riders stepping into the 650cc naked class.
