Kawasaki Motors Corp., U.S.A. issued a statement this weekend saying that the company was placing a technical hold on all 2011 Kawasaki Ninja ZX-10R sportbikes because of an undisclosed problem found to exist with the current design. While Kawasaki has been tight-lipped on what exactly is the issue with the new ZX-10R early indications seem to suggest a problem with the engine, which is an equally nebulous reason. As a part of the technical hold, Kawasaki dealers will be returning all unsold ZX-10R sportbikes to Kawasaki’s warehouses, and all sold units to customers will be bought back with a full refund.
There’s be some trouble brewing in the MotoGP/WSBK camp after news hit that MotoGP would be switching back to a 1000cc format by the 2012 season. In that story, several possibilities on how that format would work were put forth by various sides, one such proposal being the running of production based motors in MotoGP.
These motors, which would be based off those found on streetbikes, could be tuned to any degree, provided it met the criteria in the MotoGP rule book (1000cc & four-cylinders are the only regulations agreed upon currently). This news of course drew the ire of World Superbike promoter, Infront Motor Sports, in the form of Paolo Flammini, who believes that format would infringe on his license to exclusively run a production based race series.
Refusing at first to define what a production engine is, Dorna’s Carmelo Ezpeleta is now switching gears and saying the term “production engine” won’t even appear in the new MotoGP racing regulations.
One of the cooler things on display at EICMA this year was BMWs S1000RR engine cutaway. The cutaway showcases everything from airbox to exhaust, and if you look really closely you can spot the unicorns secret responsible for BMW’s 193 claimed crank horsepower. More pictures for the engineering minded after the jump.
The 2010 Honda VFR1200F is the most advanced motorcycle ever to come out of Honda’s factory, and is probably one of the most innovative motorcycles ever. A large portion of the technology that separates the VFR from the rest of the pack is the all new V4 power-plant that Honda engineers say is a trickle down product from their MotoGP racing efforts. Features and photos after the jump.
Motor manufacturer and tuner, Ilmor Engineering, has branched out from its Indy Car, Formula One, NASCAR, and MotoGP duties, and produced what they call a five-stroke motor. With dual camshafts and an asymetrical three-cylinder configuration, the Ilmor is more than intriguing with its design, and promises to bring real benefits both to the race track, and to road-use. Most notably is a 10% increased fuel efficiency, and 20% weight reduction in power-plant weight.
While not exactly “street bike” news, we thought the A&R readership would find this latest press release from KTM interesting nonetheless.
KTM owners of current SX, XC, XC-W, and EXC model dirt bikes can now have their motorcycles tuned by KTM factory technicians to the exact same specifications as the KTM factory supported race bikes.
At Jerez this weekend, the Permanent Bureau (FIM & Dorna) was light on the details when it announced that Honda would be the sole motor provider for the new Moto2 series. However after the announcement, Shuhei Nakamoto, VP of HRC, revealed more information about the engine that will be used in Moto2.
A lot of talk has gone on about who will be providing the single spec motor to the new Moto2 series. First, it was rumored that Kawasaki was promised the deal, as a part of their condition to stay on in MotoGP. Then the Grand Prix Commission opened up the contract to bidding from third-parties, which seemed to run-counter to the previous rumor, so there was a new rumor that the announcement was merely a formality. While that seemed a little ludicrous, it didn’t take long for the rumormill to start saying that the winning bid had been chosen, and was from either Honda or Yamaha (read, not Kawasaki). And now, all this talk can finally be put to rest as the GP Commission has announced that Honda will provide the motors for the Moto2 season, which is slated to start in 2010, and replace the 250cc GP class.
There’s a rumor going around that Harley-Davidson is working on a water-cooled, four cylinder, v-twin motor with a displacement somewhere between 1,300cc and 1,600cc. The good, the bad, and the ugly after the jump.
It has been confirmed, 2010 will see the debut of the Moto2 racing class, which will replace the 250cc GP. Moto2 comes about in an effort to make racing more affordable by having a second racing class that is more analogous to the bikes being built for the road, namely the middleweight 600cc segment. The Grand Prix Commission in its announcement has also revealed that Moto2 will have a single engine design, meaning all competitors will be running the same spec motor, the manufacturer of which has yet to be appointed.
