It remains to be seen what effect American Suzuki Motor Corporation's Chapter 11 bankruptcy has on its motorcycle business in the U.S. It's possible that freed from the dead weight of the car business in the U.S., Suzuki's motorcycle (and ATV and Marine) segments will flourish again. Of course, it's also possible that Suzuki's car division was helping to defray some of the motorcycle division's overhead. Either way, the motorcycle division will have to live or die on its own.
Meanwhile, I note that the other day, Dorna told Suzuki -- which had expressed an interest in a testing-the-waters return to MotoGP in 2014 -- that there was no coming back for a single season. It would have to commit to three years (2014-'16) which would bring their contracts into line with Honda, Yamaha, and Ducati. All of them are presumably contracted to compete through 2016.
Leaving aside the questionable strategic wisdom of having everyone's contract end at the same time (which wouldn't be my choice, if I was Ezpeleta) there didn't used to be much leverage in such contracts. Remember that Kawasaki basically blew MotoGP off at the beginning of the recession, and Dorna basically had to take it. Aggressively going after a manufacturer claiming, essentially, force majeure would not make the Spaniards seem like attractive business partners to any future OEMs considering entering the series.
When Kawasaki bailed out of MotoGP, it maintained a minimal presence in World SBK that started to show results last season and which really blossomed this year, with 16 podium finishes. But Dorna's hard line with Suzuki looks very different now that it also controls World SBK.
Ezpeleta hasn't said, "If Suzuki crosses us in MotoGP, we'll fuck them over in World Superbike." But you have to wonder if that's been implied. Suddenly, there really is only one game in town...
