Heads up GP fans, as the MotoGP Championship is set to close two crucial loopholes in its rulebook for the 2019 season, which the Grand Prix Commission says in its press release are needed in order to keep the sport within the spirit of the rules. The first loophole blandly affects the spec-ECU and its CAN protocol and connection, which is fairly innocuous until you read between the lines of it, while the second concerns the regulation of aerodynamic bodywork, which should be more obvious to regular MotoGP fans.If you will allow us to Tarantino these two rulebook changes, the MotoGP Championship will impose more regulation on aerodynamic bodywork, namely it will remove the loophole that allows manufacturers to change the internal structure of their don’t-call-them-winglets.
The Triumph Thruxton line is getting recalled today, for an issue that can cause the engine to stall. The recall affects 2,824 Thruxtons (both base model and R models), built for the 2016 through 2018 model years.
Specifically, the engine stall occurs when the throttle is opened or closed quickly, while the clutch lever is pulled in. Updating the bike’s ECU fixes this problem, according to Triumph, and helps stabilize the engine idle speed in this situations.
The most adorable motorcycle in Kawasaki’s lineup is getting a recall, as 9,914 units of the Z125 Pro and Z125 Pro KRT Edition motorcycles are being recalled for a faulty ECU setting.
According to documents filed with the National Highway Traffic and Safety Administration (NHTSA), the electronic control unit (ECU) may have an improper setting (ignition timing) for the fuel injection system, which would allow the engine to stall.
Momentum for a technical shake-up in WorldSBK has increased, but the manner to instigate that change is a big question. As such, the Imola paddock was full of rumor and discussion about changes to the technical regulations for 2018.
With Kawasaki and Ducati having shared all but four wins since the start of the 2015 season, there have been calls to grant other manufacturers some avenues with which to improve performance. Discussions between the manufacturers took place once again in Italy to lay down a framework for the future.
No answers were forthcoming but with Yamaha and Honda having brought all-new Superbikes to the series in the last year, and struggled to compete with the front-runners, it is clear that the winds of change may be in the air.
For 2017, Aprilia increased its involvement with the Milwaukee Aprilia bikes built and prepared in Italy. The former title-winning marque has thus far failed to live-up to preseason expectations.
The FIM is taking further steps to contain the cost of aerodynamics. The banning of winglets decided earlier this year was made on two grounds: removing the danger of being struck by a protruding wing, and reducing the potentially astronomical cost of an aerodynamic war beginning.
Banning winglets would prevent the first issue from being a problem, but would do nothing to address the second point. Indeed, with the aerodynamics cat well and truly out of the bag, the factories have already hinted that their focus would switch to fairing design.
The Grand Prix Commission have moved to stop that war starting before it begins. From 2017, factories will have to homologate fairing and front mudgard designs, with only one upgrade to each allowed per season.
The idea behind it is to allow factories to continue to develop aerodynamics, but to limit the amount of time and money spent in search of wheelie prevention.
The rules do leave one loophole open, however. The aerodynamic homologation rules apply to each rider separately. In theory, each rider on a Yamaha, Honda, or Ducati could start with a different fairing, the results of which could be assessed by the factory to help develop the next homologated version of the fairing for use in mid-season.
BMW of North America is recalling certain model year BMW G650GS & BMW G650GS Sertao motorcycles, manufactured March 8, 2013 to October 12, 2015. In total, 1,398 motorcycles are affected by this recall.
The recall centers around a software issue in the bikes’ engine control unit (ECU), which cause an affected motorcycle to stall, thus increasing the risk of a crash.
To rectify the situation, BMW will notify affect G650GS owners, and BMW dealers will update the ECU software, free of charge. This recall is expected to begin November 18, 2016. Owners should note that this recall supersedes recall 15V-537.
The Kawasaki Ninja ZX-10R is a perfectly capable superbike on the track, but as with any bike available for the street, compromises have to be made. That’s why Kawasaki always makes special factory racing parts, available right from your local Kawasaki dealer. For the 2016 Kawasaki Ninja ZX-10R, things are no different, and now Kawasaki has released this year’s go-fast parts catalog. If you are a privateer, looking for some factory-backed performance, this should be your first stop before your racing season begins. Tasty items include an adjustable ECU that optimizes fuel, ignition, timing, over-rev, traction control, launch control, etc. There is also an ABS dongle that can disable anti-locking brakes for one or both of the wheels.
MotoGP’s Technical Director has rejected KTM’s claim that Honda exceeded the official Moto3 rev limit during the 2015 season.
In an official statement issued today, Danny Aldridge said that he and his technical team had examined the official rev limiter used in Moto3 and verified that it was operating correctly, and that although there had been overshoots of the rev limit, these were very small and very brief.
Aldridge went on to confirm much of what we had found when we investigated the issue at the end of February. Speaking to Peter Bom, crew chief of 2015 Moto3 world champion on a Honda Danny Kent, Bom explained that the issue had been about the way in which Honda had optimized the point at which the rev limiter cut in, and this is what had caused the confusion.
Were Honda exceeding the Moto3 rev limit in 2015? This is the accusation made by KTM Sports Director Pit Beirer in a story on the German-language website Speedweek. Beirer alleges that KTM came across the issue when talking to riders who switched from Honda to KTM this year, who were complaining of how abruptly the KTM hit the rev limiter. Beirer further claims that KTM were able to look at the data of the Honda Moto3 machine held by a former Honda mechanic. In that data, he alleges, the Honda ran flat out to the 13,500 RPM rev limit, then gradually tailed off to 13,600 RPM. These claims, if they are true, would be a massive breach of the Moto3 regulations. The insinuation was that this may have been a factor in a Moto3 title that ended up being decided by just six points.
When the minutes of the latest meeting of MotoGP’s ruling body, the Grand Prix Commission, were unveiled, there was one passage which confused many who read it.
The press release included a paragraph on the spec software which is to be adopted for all MotoGP bikes from the start of the 2016 season. The passage read as follows:
It was already announced that Factory teams in the MotoGP class must move to using unified software with effect from 01 July 2015. It has now been confirmed that different teams, using machines from the same Factory, may use different versions of the unified software.
The wording seemed to suggest that from 2016, factory teams would still be allowed to use a different version of the ECU software to that used by satellite and private teams.
