MV Agusta is returning to its racing heritage next season, as the Italian company has announced that it will be fielding a factory World Supersport effort with the venerable ParkinGO team in 2013. Forging a three-year contract, ParkinGO will race the MV Agusta F3 675 in WSS, with MV Agusta providing technical support on the F3 from the factory in Varese.

Inked on what would have been Claudio Castiglioni’s 65th birthday, the agreement sees the return of MV Agusta to the World Superbike Championship series, and could be a stepping stone for the Italian brand back into the Superbike class at a later time.

A prudent ally, ParkinGO is no stranger to WSS or WSBK, having won the World Supersport title in 2011, and making a strong showing in the 2012 World Superbike season, both with Chaz Davies.

HRC has announced that it has signed Stefan Bradl as a “factory-supported” rider through the 2014 season. The move is surely a reward for Bradl, who easily claimed MotoGP’s “Rookie of the Year” distinction, and perhaps more importantly, showed extreme talent aboard the Honda RC213V.

Said to already have been using a factory-spec frame (Dani Pedrosa’s rejects) for the latter part of the season, it is not clear how much this announcement will change Bradl’s true support from HRC, but it certainly can’t hurt the young German’s chances. Bradl will stay within the LCR Honda team in 2013 & 2014.

All the conjecture about Ducati’s factory World Superbike team can now come to a halt, as the Italian brand has announced that Francis Batta’s Belgian organisation, Team Alstare will take over the reigns of the company’s new WSBK effort.

At the helm of the Ducati 1199 Panigale RS13 will be former WSBK Champion Carlos Checa, who will be joined by Ayrton Badovini. Handling Ducati’s World Superbike campaign for the next two years, Alstare takes over from Althea Racing — a move that made headlines just a week ago.

Forced to go to World Superbike for the 2012 season, Hiroshi Aoyama will return to the big show for the 2013 season, with the Avintia Blusens team. Trading his Honda CBR1000RR superbike for a Kawasaki-powered CRT entry, Aoyama will perhaps miss the days when he was on a Honda RC212V prototype, but certainly won’t miss the Pirelli-shod production machine, which he only managed to race to a 18th place championship points finish.

Entirely unimpressive in WSBK, Aoyama has something that many CRT riders do not: experience on the tricky Bridgestone tires. That fact alone should make Aoyama a potent weapon for the Avintia Blusens squad, which has struggled to develop its CRT entry — due partially to the talent on the machine. With the help of Aoyama’s MotoGP experience, and 250GP Championship title behind him, the BQR team might find some more traction and direction with its work — having Hector Barbera along for the ride as a teammate won’t hurt either.

Fresh off the heels of him wining the 2012 World Superbike Championship, question marks surround Max Biaggi — will he stay with Aprilia for another season and defend his title? Or, will he end his motorcycle racing career on a high, having just collected his sixth world title?

The crystal ball on this subject is uncertain. Though still not re-signed with the factory Aprilia squad for the next World Superbike Championship season, Biaggi did take part in the latest WSBK test at Aragon, which certainly lead to some believing the Roman Emperor would race for at least another season.

It was a strange day in Malaysia. Part of the strangeness was down to the weather. The familiar pattern of disrupted sessions as the rain fell, but not hard enough to allow the MotoGP riders, in particular, to spend much time on the track in the afternoon.

There was a twist, however, a particularly Malaysian one at Sepang: the heavy shower which passed over the track at the start of the afternoon session for MotoGP left part of the circuit soaking, with water a couple of centimeters deep at turns 1 and 2, while the rest of the circuit quickly dried out almost completely. It at least added a little novelty to the disruption, along with the frustration of another wasted practice.

The real strangeness came at the start of the day, however. It took about 10 minutes for observers to notice that Maverick Viñales had not gone out on track and there was suspiciously little activity in the Avintia Blusens garage. Once they noticed, low-level pandemonium broke out: within seconds, a throng of Spanish journalists crowded out of the media center and hastened on their way into the paddock, to find anyone and everyone and learn what they could.

As they drifted back in, and as TV pictures started to appear showing an empty Blusens garage, Viñales walking through the paddock accompanied by his father and the Dorna media officer, and team managers Raul Romero and Ricard Jové gathered in discussions, it was clear that there was something very wrong.

When it was revealed what that was – that Viñales had decided to quit the team with immediate effect – it sent a shockwave through the paddock. Riders quitting teams with races left in the championship is unusual; to do it while that rider is second in the title chase and still in with a shot at the championship is unheard of in motorsport.

Some more controversy is brooding for World Superbike rider Sylvain Guintoli, as Paul Denning and the FIXI Crescent Suzuki have slammed the British-living French-born rider for backing out of his 2013 commitments with the team. Issuing a statement to the press, Crescent Suzuki states that Guintoli and the team came to a “full and final agreement” at Magny-Cours, which was singed by the Frenchman.

According to Crescent Suzuki, Guinters made significant steps with the team to test at Aragaon starting today, but since that agreement, Guintoli has informed the team that he has to back out of his testing obligation in order to consider a new offer from a rival team. That rival team is heavily rumored to be Aprilia Racing, which may be scrambling to find a replacement rider for the still undecided Max Biaggi, the now-current World Superbike Champion.

For devout WSBK fans, the statements from FIXI Crescent Suzuki sound similar to those made by Liberty Racing, when the Czech team let Guintoli go mid-season, citing a number of reasons, including the Frenchman’s on-track results. Starting strong early on, Liberty Racing’s swan song started at Monza, and ultimately saw the team release its riders one-by-one, before finally missing the last race at Magny-Cours altogether.

For added Drama Llama, the press statement from FIXI Crescent Suzuki and Paul Denning is after the jump.

The mystery of the final MotoGP prototype seat has been solved: after months of negotiations, Alvaro Bautista has finally retained the Honda RC213V ride with the San Carlo Gresini Honda team. The Spaniard will remain with the Italian team for another season.

The contract extension has come at a cost, however: Bautista has had to take a drastic cut in his salary to stay with the team. According to the Spanish website Motocuatro.com, Bautista’s wage has been slashed to five figures, with the amount of 90,000 euros being passed down the paddock grapevine.

The Twin Ring Motegi circuit is to be home to the Japanese round of MotoGP until at least 2018. Dorna today announced that a contract had been signed with the circuit for it to host the Japanese Grand Prix from 2014 to 2018. Motegi has been on the calendar since 1999, first running the Pacific Grand Prix before taking over the Japanese Grand Prix when Suzuka was axed from the calendar following Daijiro Kato’s death.

There had been some doubt about the future of the circuit in the aftermath of the 2011 earthquake and tsunami. Motegi is just over 120km away from the Fukushima Daiichi nuclear plant which was badly damaged by the tsunami, and caused a massive leak of radiation.

The Power Electronics Aspar Team confirmed today that it has extended the contracts of current riders Randy de Puniet and Aleix Espargaro for the 2013 season. Both the Frenchman and the Spaniard are to remain with Aspar for another year, and will once again contest the season on Aprilia-built ART machines under the Claiming Rule Team regulations. The two teammates are currently battling it out to take the honors as top CRT rider for 2012.

The Aspar team has been the showcase for the CRT rules this season, with both De Puniet and Espargaro closing the gap on the prototype bikes. How the team will fare next year when most of the other CRT bikes will start to use the highly advanced Magneti Marelli ECU, while they stick with Aprilia’s electronics package developed in World Superbikes remains to be seen, and will provide a good yardstick by which to measure the spec ECU on offer.

With the prototype rides all filling up quickly, remaining with Aspar was the best option for both men. With a year of development on them, the Aprilia CRT bikes should be even closer to the prototypes next year, allowing De Puniet and Espargaro to put themselves in the shop window for the 2014 season, when Suzuki makes a return to MotoGP, and more factory rides should be available.

After the jump is the press release from the Aspar team announcing the re-signing of its current riders.
