Kawasaki is recalling 4,170 units of its  ZX-10R motorcycle for an oil leak that may come out from the crankcase. The recall only affects 2011 & 2012 Kawasaki Ninja ZX-10R models (ZX1000 JBF / JBFL / KBF / KBFL / JCF / JCFL / KCF / KCFL), and deals with leaking that occurs at the mounting point for the starter motor, which then causes the oil to pool at the top of the crankcase.

Kawasaki’s obvious intent with the recall is to address the possibility that the leak could increase the American market’s dependence on foreign oil, due to the needless amounts of petroleum that would be lost because of the leak. In addition to that hot-button topic, the issue of the oil dripping onto, or in front of, the rear tire is a serious safety concern, which is being addressed by Kawasaki’s recall since it could cause a lack of adhesion.

The quarter-liter sport bike market is about to get more interesting, as photos of the 2013 Kawasaki Nina 250R have sprung from Kawasaki Japan’s corporate site, ahead of the bike’s presumed late-fall international launch. Revising the long-time tested aesthetic of the previous generation Kawasaki 250R, the 2013 model takes more than a few cues from the current generation Kawasaki ZX-10R.

One of the best selling motorcycles in the United States, the Kawasaki Ninja 250R is surely feeling the pressure from Big Red, as the Honda CBR250R came to market last year, and has been a strong seller locally and internationally. With KTM to bring a 350cc sport bike to the USA in 2014, and other manufacturers eyeing the learner-bike model segment, Kawasaki has surely been feeling its dominant position in this space coming under fire, and has acted in response.

For the next model year, Kawasaki is giving a modest update to its flagship model, the 2013 Kawasaki Ninja ZX-10R. Mostly touching up its work from 2011 with a dollop of new paint, the one intriguing feature of the 2013 Kawasaki ZX-10R is its new electronic steering damper, which adjusts the level of steering damping based on how fast the motorcycle is traveling.

Kawasaki developed the damper with the help of a little Swedish company named Öhlins, and is the first manufacturer to use the new suspension from the famed suspension brand, which is sure to be a standard item on the bikes of other OEMs in the coming years — just like the Honda Electronic Steering Damper (HESD) that Big Red debuted circa 2004.

With MotoGP adopting a CRT rule for the 2012 season, a provision that allows production motors to be used in a prototype chassis, the World Superbike Championship has been feeling its production-racing turf a bit infringed upon. Now whether or not the latest rule change from WSBK has anything to with what is going on between the two series is up for debate, but regardless for 2013 and onward, World Superbike teams will have to run faux-headlight decals on their race bikes — in some sort of attempt to link what is on the track to what is sitting on dealership showroom floors.

First to adopt the rule is the factory Kawasaki Racing Team, which has added the headlight decals to the Kawasaki Ninja ZX-10R race bikes that are being ridden by Tom Sykes and Loris Baz this weekend at Aragon, Spain. In addition to the headlight sticker rule, teams will have to run 17″ wheels starting in 2013, which is being pitched as a cost-savings measure, but is more likely grounded in the idea of further making the illusion that what is raced in WSBK is somehow remotely linked to what motorcyclists purchase.

If you believe the motorcycle rumor mill, the now long-in-the-tooth Kawasaki Ninja ZX-6R is set to get an update next model year. Now four years old, the ZX-6R has long shared a common thread with its 1,000cc brethren, the Kawasaki Ninja ZX-10R. With the ZX-10R now two-model-years-old though, the clock has been ticking as to when Kawasaki would give the ZX-6R a similar makeover. While still simply an internet rumor, there does seem to be some logic to the idea that we could see a new Kawasaki ZX-6R by the end of the year, though nothing can be for certain.

Talking to a few of the Bournemouth Kawasaki Racing mechanics this afternoon in the Isle of Man TT paddock, unfortunately it looks like the the team’s electric entry, the Kawasaki-Zytek ZX10ev, is going to be a scratch for the 2012 SES TT Zero race.

When asked why the Kawasaki-Zytek entry would not be racing, the team cited the bike not being ready for the 2012 Isle of Man TT, intoning that the Kawasaki-Zytek ZX10ev’s first laps ever would be on the Isle itself. Considering that the Kawasaki electric racing effort has been in the works for over a year now, the news is a bit surprising that it hasn’t been as extensively tested as its Honda Mugen counterpart.

Encircled by the gorgeous Wasatch and Oquirrh mountain ranges, Miller Motorsports Park has some of the most dramatic backdrops out of all the World Superbike venues, though coupled with the track’s 4,000+ foot elevation, the weather can be wet and cold at times. Such words were probably an understatement for the conditions on Sunday, as frigid temperatures and rain prevailed in the day’s earlier sessions. Realizing that some Superpole qualifying was scheduled for later though, the weather gods appeased the American crowd, who had been braving the conditions, and quickly dried the track for World Superbike qualifying.

Down on power at the very fast track, the Ducatis of Smrz and Checa surprised everyone with their dominance on the time sheets. Of course, Tom Sykes could not be counted out from the qualifying fun, as the Englishman has taken four of the past five pole positions. One of only two stops on the WSBK calendar that is outside of Europe, American fans were treated on this Memorial Day weekend to some fine qualifying, which included some upsets. Results after the jump.

With Honda’s electric motorcycle racing effort thinly disguised as the Mugen Shinden and getting a tremendous amount of attention, the motorcycle racing press missed the very subtle joint-entry by Zytek Automotive and Bournemouth Kawasaki Racing into the 2012 TT Zero. Already incorporating one of the most advanced technology groups in electric and hybrid automotive technology, as well as one of the top Isle of Man TT racing teams, the Kawasaki-Zytek ZX10ev race bike also benefits from another important element: the backing of Kawasaki Motors UK.

Using one of Zytek’s 100 kW (134 hp) permanent magnet oil-cooled KERS motors for its power plant, the Kawasaki-Zytek ZX10ev has the added benefit of a six-speed gearbox, which like the bike’s chassis, is a recycled component from the Kawasaki Ninja ZX-10R donor bike the electric racer is built from. Using the firm’s automotive racing experience to its benefit, Zytek’s motor design has previously been used on the company’s Hybrid Le-Mans 24 hour race-winning car, and uses technology similar to Zytek KERS system used in the 2009 Formula 1 Championship.

Powering the motor will be four 15Ah LiFeP04 cylindrical cell battery packs, which have been located in the ZX-10R’s fuel tank, airbox, radiator, & exhaust for a total of 11.8 kWh in energy storage. “The shape of the Ninja ZX-10R frame is designed to curve around a conventional engine, and does not lend itself naturally to the fitment of a battery,” said Zytek Project Manager Des Hill. “We have ended up filling the area normally use by the tank, air-box, radiator and exhaust with four sculpted packs. In total we have 240 power cells carefully distributed around the bike.”

Let’s play a game for a minute. Who is the third largest motorcycle manufacturer in the world? One of the Big Four maybe (Honda, Kawasaki, Suzuki, & Yamaha), that is after all what their name implies, right? Maybe you think it is a European manufacturer, like BMW or Triumph? If these were any of your answers, thank you for playing, but please try again.

Hitting over 210 mph down the front straight at Monza, Tom Sykes became the fast two-wheeled man in World Superbike history. Setting the speed on his Kawasaki Ninja ZX-10R, Sykes got a bit of help from Aprilia-man Max Biaggi, as the Brit slip-streamed behind the Italian part of the way down the track. Making the effort on rain tires, Sykes will have to start tomorrow’s races from the second grid position, unable to take advantage of the drying track on slicks, as pole-setter Sylvain Guintoli did.

“When I hit the new record top speed I could feel that the rpm was higher and I knew from the note of the engine that it was more than on previous laps,” said Sykes. “I could not have timed my run to get into Biaggi’s slipstream any better. I had a fantastic run out of Parabolica and I used Max’s draft all the way down the straight. If we had more time we could have come back in and gone with a slick rear or intermediate rear and made the difference, but it wasn’t to be.”

“We did a great last lap on wet tyres and starting from second on the grid is not too bad. It is a front row start and that is the main thing,” the Brit continued. “The competitive side of me for sure is disappointed not to keep the run of Superpole wins going but tomorrow is the one that counts. It’s great for Kawasaki and myself to be on the front row and it is a lot better starting slot for tomorrow. We have good pace in the dry and I do not think the wet will be an issue either. A dry race would be better for everybody.”
