Now, the question yet to be answered is whether the American market will continue its bone-headed aversion to any sportbike without a full fairing. If they do, they will be missing out on one of the best performance bargains available.
I once had a first-gen Z1000 as a long-term project bike, which gave me plenty of time to learn its strong points and its deficiencies. Its distinctive styling and hooligan demeanor gave it an enthralling personality, but those positive attributes were countered by an unbalanced suspension and a vibey motor. The old Z had its fans, but there weren't enough of them. A 2007 revision calmed the annoying vibes and had midrange-enhancing tricks to go along with its freshened cosmetics, but continued slow sales caused it to be dropped from Kawi's 2009 lineup.
No matter, because the 2010 model is new from the ground up. Improvements are so vast that comparisons to the previous iteration are pointless. It's a well-engineered street-fighting machine that will be difficult to humble by any of the illustrious naked sports bikes from Europe.
The new Zee begins with a completely new chassis and motor. Aluminum now makes up the frame (and swingarm), lighter and stronger than the previous steel frame. Rake and trail (24.5 degrees/4.05 inches) are identical to the old bike, but it handles with poise the original could only dream about.
Wheels spaced nearly an inch further apart add stability, yet a weight reduction and improved mass centralization contributes to exceptional agility for its displacement. With its smallish 4.0-gallon tank full, it scales in 22 lbs lighter (481 lbs) than its 4.9-gallon progenitor, for a net reduction of 16 lbs, 9 lbs of it solely from the new alloy frame.
The Z-Thou's engine is a completely new inline-Four, sharing nothing with the old Zee or the ZX-10R Now displacing 1043cc, the fuel-injected mill gains 90cc and a secondary balancer from previous. The stressed-member engine now mounts to the frame in four rather than three mounting points, with a rubber mount above the transmission to reduce the, er, transmission of vibration.
A cold-air induction system is fed by intakes on each side of the fuel tank and through the frame to a non-pressurized airbox. A tuned “howl” is designed in by using a specifically shaped resonator chamber – a strategically placed hole functions similar to blowing over a bottle's mouth. Oval-shaped 38mm throttle bodies are fed by differential-length intake snorkels to assist a torquey, broad powerband
Header pipes are linked with crossover tubes then into a large chamber beneath the engine. As such, each controversially styled muffler doesn't require as much volume, reducing weight by 1.5 lbs each. A valve in the exhaust exists only in the right-side muffler (like the 2007-and-up versions).
Kawi says the engine spits out 138 crankshaft horsepower at 9600 revs, which will likely convert to nearly 125 ponies at the rear tire. Torque is rated at a considerable 81.1 ft-lbs at 7800 rpm. After wringing the Zee's neck (and later my rain gear) romping around the soggy Cambria, California, I can say that not many people will be wishing for more power.
Suspension is by Showa. The 41mm inverted fork now includes compression-damping adjustability to the previous preload and rebound, while the horizontally placed monoshock lacks only compression-damping control. Rear preload, sadly, is by finicky locking rings rather than the easy-to-tweak ramp-style collar.

Japanese European Style
In Europe, the Zee is Zed, and it's been a hot seller on the Continent. As such, the bike's new avant-garde styling is directed at a Euro tastebud, as interpreted by a Japanese company. Trying to avoid being called a “standard,” the Zed's appearance is Italian MV Agusta Brutale blended with Japanese anime inspiration. It is an edgy, future-forward design that has polarized pundits after seeing the first pictures.
The Zee comes off more attractive in person, looking muscular and distinctive. The central area of the bike is densely packaged, leaving the blunt front end and tidy tailsection appearing relatively diminutive. The black-anodized cast-aluminum frame spars wrap tightly over the engine and narrow around the bike's waist for a slim fit for a rider.
Although not fully faired, the Zee incorporates small side panels that wrap around the radiator, plus an angular chin fairing that bleeds into a black exhaust cover. Dual twin-exit mufflers continue the bike's quad-exit theme seen on the Z1000's previous two generations. Its cast-aluminum wheels receive machined edges on the rims and spoke ends for a custom look that adds some bling.
|A Naked Sportbike: Will it sell in America this time around?|
Albert Einstein's definition of insanity is doing the same thing over and over again and expecting different results. After two underwhelming attempts to peddle a streetfighter-style naked sportbike, one wonders if Kawasaki Motors Corp USA might be a little demented. They say the Z1000 is different this time around.
“This really is one bike that a lot of people at Kawasaki are excited about,” commented Karl Edmondson, KMC's Product Manager.
KMC had been frustrated by the sales performance of the previous Z1000s, especially since the bike was perennially near the top of the sales charts in Europe. Like other OEMs in America who had been burned by tepid response to naked sportbikes, Kawasaki had nearly given up hope on category, evidenced by the recently revised 2007 edition being dropped from the lineup in '09.
When word came from Japan that a new Z1000 was being prepared for a 2010 launch, KMC yawned – thanks but no thanks. However, that was before Edmondson and his boss rode the pre-production development Z1000 at Kawi's racetrack in Japan. They enjoyed the Z more than they ever thought possible, causing KMC to make an abrupt about-face and deciding to give the much improved Z another chance at the North American market.
KMC knows it has a potential hit on its hands if American sport riders can get over their irrational fear that a sportbike without a fairing can't really be a sportbike. They – like the staff at Motorcycle.com – believe in the versatility and reasonable comfort offered by a naked roadster like the Z.
In 2002, Kawasaki announced a tighter focus on racetrack abilities for its sportbikes. But the ultra-sporting ZXs aren't optimum for sportbike riders who don't ride on the track. It's a simple fact that a racebike will be compromised in terms of its street performance, but race-replica 600cc sportbikes nevertheless make up about 50% of the American sportbike market.
Kawi notes that sport riders want the best of everything and that the common perception is one needs to buy a premium sportbike to get “the best.” The Z1000 intends to obliterate that perception.
“I was one of those who wasn't really a fan of the old bike,” Edmondson admitted, “but nothing on this bike is carried over from the old bike. “Now, for a lot of people at KMC, this is their favorite bike.”
“It's not your father's Z1000,” added Jeff Herzog, Senior Media Relations Coordinator for KMC. “It's a Versys on steroids.”
Despite a bulky appearance, the Z proves to be quite slender between a rider's knees, making for a straight shot at the ground for short legs to feel secure despite the seat located 32.1 inches off the pavement, and it broadens further rearward for better support. The upright riding position feels just about perfect, with the solid-mount (previously rubber-mounted) tubular handlebar neither too far forward nor too far back. Tall riders might wish for a bit more space between the seat and pegs for their legs, but a generous amount of fore/aft room on the seat aids comfort for all.
Controls are easily accessed, and an adjustable front brake lever fits every hand. The cable-actuated clutch requires a medium-effort pull at the non-adjustable lever, and gear changes are kicked with minimal effort. Images from the diamond-shaped mirrors aren't great for a naked roadster, as forearms partially obstruct the unblurred view behind.
Kawi cleverly made the compact gauge package tiltable to three positions, but instrumentation isn't the Z's strongest aspect. While the LCD speedo is easy to read and a fuel gauge and clock are convenient, the bar-graph tachometer display is too small to read at a glance, and we're continually bemused why some manufacturers don't bother including a gear-position indicator – the ECUs of all modern bikes know what gear the transmission is in, so why can't its rider? We also think the yellow tinted gauge face is a little goofy.
However, instrument efficacy will be far from your mind once the big Z is set into motion. Locomotive torque and a wide clutch engagement bring you quickly up to whatever speed may be required. Cat-quick steering response allows the streetfighter to carve traffic and canyons with equal aplomb. I was surprised by how it was able to be maneuvered fairly handily with only leg inputs, tossing it back and forth between the knees without aid from the handlebar.
With an open road ahead of us, feeding in a handful of throttle elicited even bigger grins. It pulls strongly from anywhere in the seemingly lumpless powerband. Compared to the old Z, it has more power from top to bottom. Acceleration in the lower gears is so intense that the Z feels like it wants wants to headshake but doesn't. Hooligan types will be happy to learn that wheelies in first gear are effortless, and just slightly less so in second. Smooth throttle response assures a rider gets exactly the power wanted, and a soft rev limiter cuts in gently if you accidentally over-rev it past its 11K redline.
"It pulls strongly from anywhere in the seemingly lumpless powerband."
The new Z's suspension proves to be compliant yet controlled, a huge improvement from the unbalanced system of the original Z. Brakes weren't tested much on our cold and wet day, but the radial-mount 4-piston calipers and 300mm petal-shaped rotors promise good power. Initial bite isn't intimidating, and feedback from the radial-pump master cylinder is quite good. Dunlop D210 tires supplied reasonable grip in the potentially treacherous condition we rode in.
Vestigial side panels offer a moderate amount of wind protection for legs plus a location for the integrated front turn indicators, but a rider's torso receives little deflection from the elements – this is a naked bike, dummy. A taller flyscreen would be welcome on cold days or long trips. Passengers will feel secure thanks to integrated grab handles cleverly built into the die-cast aluminum subframe. The addition of a counterbalancer drastically damps out the annoying vibrations of the previous model.
We could whine about the Z1000's gauges or lack of rear compression-damping adjustability, but those minor demerits add up to nearly nothing when factoring in the dynamic experience of piloting the fervid yet manageable Z1000. This truly is a sportbike that can entertain a hardcore sport rider yet be a dextrous and multifaceted motorcycle for real-world riding conditions.
In these days of rapidly escalating prices, sporting motorcycles don't come much more value packed than the Z at its $10,499 MSRP. In fact, the 2010 ZX-6R stickers at an identical price, which works out to be $17.50 per cubic centimeter of engine displacement. The Z1000 costs only about 10 bucks per cc!
"...Motorcycles don't come much more value packed than the Z...The Z1000 costs only about 10 bucks per cc!"
We've been smitten by the Z in its previous nasty but flawed version, and now it's gotten all of its wrinkles ironed out and wields an even bigger punch. Now let's see if America is ready to throw down for one of the most entertaining sportbikes for the street we know of, fairing or not.
