Three years of unparalleled success has seen Jonathan Rea notch up 39 victories, 70 podiums, and 3 WorldSBK titles. To put those numbers into context, only Carl Fogarty, Troy Bayliss, and Noriyuki Haga have won more races in their WorldSBK careers. It truly has been a historic run of form for Rea and Kawasaki. For WorldSBK though the achievements have been outweighed by the reaction of fans to these results. Feeling that significant changes were needed to ensure a more competitive balance for the field, WorldSBK has introduced a wide range of new regulations to curtail the Kawasaki dominance. The goal isn’t to stop Rea and Kawasaki winning but simply to allow other manufacturers to get on an even keel.

Scott Smart has been tasked with writing and rewriting the rule book for Superbikes around the planet. The FIM Superbike Technical Director has been instrumental in bringing about the recent regulation changes for WorldSBK, and speaking at the season ending Qatar round he explained the philosophy behind the changes. “There’s a lot of benefits to these changes, but the biggest factor is that we want to find a way to have more exciting racing in WorldSBK,” explained Smart. “With the new regulations each team on the grid has the chance to run the same specification as the factory teams or to develop their own parts. This gives a private team the chance to have a bike with development work already having been completed by simply buying the relevant parts for their bike.”

The World Superbike championship has moved to address the performance disparities that have seen Kawasaki and Ducati dominate in recent seasons.

The Superbike Commission, the rule-making body for the WorldSBK series, today announced a series of measures to ensure greater parity among teams and factories.

The measures, which will enter into force in 2018, see rev limits replacing weight penalties and air restrictors as a performance balancing mechanism, and a performance-based concession point system for allowing engine updates during the season.

The changes fall into three main categories: the performance balancing system, a system of concession points, and the price capping of a range of suspension, chassis, and engine parts related to performance.

The performance balancing system and the concession points system are aimed at creating more parity between different manufacturers, while the price capping of certain parts is aimed at both limiting costs, and of ensuring that all teams have access to the same parts.

Yamaha have issued an official explanation for the problem they suffered at Mugello, which saw Valentino Rossi’s engine blow up during the race, and Jorge Lorenzo’s engine blow up during warm-up on Sunday morning. The cause given is exactly in line with the reasoning in our Mugello Sunday post-race round up: the engine overrevving as the rear wheel lifted at the end of the Mugello straight. At that point in the track, with the bike hitting 350 km/h and nearing peak speed at top gear and at full throttle, when the rear wheel lifts over the crest at the end of the straight, the engine spins up too quickly for the rev limiter to catch.

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.

The news that 340mm carbon brake discs are to be allowed once again in MotoGP has rekindled a debate that has been going on behind the scenes for some time.

The move to allow the discs at all tracks, and not just Motegi where they are already compulsory, has come as both power and weight of the MotoGP machines has grown over the past three years. But the real solution lies in reducing the minimum weight.

There was a certain irony in the moment chosen by the Grand Prix Commission to ban carbon discs larger than 320mm. The move – made for reason of cost savings and rationalization – came just as MotoGP was to return to 1000cc, meaning the bikes were about to reach higher top speeds.

Compounding the problem, the minimum weight was also increased. The initial proposal was to raise the minimum from 150kg, the weight of the old 800cc machines, to 153kg. However, to make life easier for the CRT machines, the weight limit was raised even further, in two steps, to 157kg in 2012 and 160kg in 2013.

In the space of two years, engine capacity had been increased by 25%, leading to a power increase of around 10%, while weight had also been increased by nearly 7%. It was a recipe for brake problems, and that is precisely what occurred.

After a week of debate and discussion, the Grand Prix Commission has finally reached an agreement on the Factory 2 class. It took many hours of phone calls, and full agreement was not reached until late on Monday afternoon, but the agreement contains some significant changes to the long-term future of the MotoGP championship.

The Factory 2 proposal has been adopted in a slightly modified guise, with any manufacturer entering in the Open class liable to lose fuel and soft tires should they win races. But the bigger news is that the full MotoGP class will switch to use the spec software and ECU from the 2016 season, a year earlier than expected.

The proposals adopted by the GPC now lays out a plan for MotoGP moving forward to 2016. In 2014 and 2015, there will be only two categories – Open and Factory Option – with the set of rules agreed at the end of last year.

The new proposal sees manufacturers without a dry weather win in three years to compete as Factory Option entries, but with all of the advantages of the Open class – more fuel, more tires, no engine freeze and unlimited testing. However, should they start to achieve success, they will start to lose first fuel, and then the soft tires.

If Ducati – for it is mainly Ducati to which these rules apply, as they are currently the only manufacturer who are eligible at the moment – score 1 win, 2 second place finishes or 3 third places during dry races, then all bikes entered by Ducati will have their fuel cut from 24 to 22 liters for each race.

Should Ducati win 3 races in the dry, they will also lose use of the softer rear tires which the Open category entries can use. If Ducati were to lose the extra fuel or tires during 2014, they would also have to race under the same conditions in 2015.

Much was expected of this Friday’s meeting of the Grand Prix Commission, but in the end, the decisions taken were relatively minor. Dorna, IRTA, the FIM, and the MSMA agreed on a number of proposals which had widely been expected, but made no real progress on the major rule changes expected for the 2014 or 2015 season.

The rule change with the biggest immediate impact was the dropping of the Rookie Rule, as we reported during the Silverstone round of MotoGP. The dropping of the Rookie Rule, which prevents new entries into the MotoGP class from going straight to a factory team, opens the way for Marc Marquez to join the factory Repsol Honda team next season. Contrary to popular opinion, however, the rule was not dropped at the request of HRC, but rather of the Honda satellite teams themselves, both Lucio Cecchinello and Fausto Gresini fearing the disruption that Marquez would bring for just a single year.

Jerez saw another round in the game of bluff poker being played between Dorna and the manufacturers over the future of MotoGP’s rules, and both sides took another step closer to an agreement. Reports emanating from the discussions suggest that Dorna has made a concession to the MSMA over the rev limits, while the factories are pushing through a single-bike rule, and an agreement should be ready by the middle of the year.

Ever since the MSMA lost their monopoly over the rules at the end of 2011, when the contract between the MSMA and Dorna lapsed, Dorna has had the stronger hand, and Carmelo Ezpeleta has been pushing the factories hard for changes. The pressure is starting to pay off for Ezpeleta, as by a combination of cajoling, threats and promises, he has also reached an agreement over the future shape of the sport. MotoGP is to undergo a radical transformation from the pure technology exercise that was the 800cc era, and become a sport focused on entertainment, where costs are kept in check.

We just got off the phone with Kawasaki HQ, and it’s official: the 2011 Kawasaki ZX-10R will inadvertently get a power decrease when it comes to the United States because of the EPA’s regulation of noise pollution, confirming earlier rumors from this week. Because of the EPA’s new methodology for measuring exhaust noise levels, the 2011 Kawasaki ZX-10R passes the Euro III standards, but fails the EPA standards in its unadulterated form. To come into compliance with the EPA’s Noise Control Act, Kawasaki has lowered the rev-limit on the 2011 Kawasaki ZX-10R by 750 rpm in order to meet the new criteria.
